Through CAMPEM, Cepel participates in public hearings and legal proceedings, in the elaboration of technical standards, in the provision of consulting services to sector entities, such as Aneel, and also participates in the Electromagnetic Fields Project, conducted by the World Health Organization (WHO).

ANAREDE

It is the most used program in Brazil for the analysis of electrical power systems in a steady state, both in expansion planning studies and in operation planning. In addition to several network analysis functions, ANAREDE also provides the initial solution for other programs, such as ANATEM, ANAFAS and PacDyn. ANAREDE is widely used by public and private electric energy generation, transmission and distribution companies, sector entities, consultants, and universities. It is also used in other countries, such as England, Italy, Spain, Denmark, and Angola.

AnaHVDC

The AnaHVDC program simulates the dynamic behavior of large electrical power systems with multiple direct current links in a multi-infeed configuration (a condition in which multiple direct current links deliver power at electrically close points in an electrical power system). The program uses dynamic phasor-based models to represent electromechanical and electromagnetic transients via phasor modeling without loss of precision. It is an innovative solution, the only one in the world to enable this type of simulation in large systems. Among the many features of AnaHVDC is the possibility of considering the complete modeling of the power system, with all components represented in a stability study, and also the electromagnetic transients. An important feature that the program offers is obtaining the waveforms of the DC link valves that allow for representing commutation failures. The program has the potential for different applications in planning the operation and expansion of electric power generation.

The platform allows for the collection and analysis of data on the environment, sustainability, business performance, R&D+I, governance, risk, and compliance (GRC), helping to monitor goals and decision-making processes. The computed data also helps in meeting the demands of investors, whether in the responses to the questionnaires on the sustainability indexes of the stock exchanges (ISE/B3 and Dow Jones Sustainability Index) by the Eletrobras Companies or other reports aimed at these stakeholders.

Cepel Methodology for calculating uncertainties and estimating P90 energy production from wind farms

The entire process of contracting the purchase and sale of electricity from wind power requires that the estimate of energy production P90 be calculated from the identification and quantification of the uncertainties involved in the process of calculating this production. As the uncertainty values are given by specialized certifiers s, the classification and the methodology for calculating the uncertainties are not explained and, for a long period, only a number was provided. To make the procedure for calculating the uncertainties involved in estimating the energy production of a wind farm more transparent, Cepel developed a fully traceable methodology that contributes to a better assessment of the uncertainties and risks of the investment in question. The methodology also meets the new EPE requirements for the qualification of wind projects.

LCOH

Useful in the field of hydrogen technologies, LCOH is a calculator that provides the leveled cost of hydrogen. The tool has a friendly and interactive interface, making the LCOH result available immediately on the cell phone screen or the computer, and can be accessed via the web, free of charge. Using international parameters to carry out preliminary economic feasibility analyzes of green hydrogen plants, allow the comparison of the production cost of the latter with the cost of hydrogen produced based on other energy resources, such as natural gas.

SMARTe

The Remote Monitoring and Analysis System for Electromagnetic Transients is in the final stage of development. Unparalleled on the market, it is capable of measuring, recording, and carrying out a preliminary analysis of disturbances in the network, without interrupting the operation. It thus makes it possible to obtain information about the transient requests that the equipment suffers during its operation, contributing to management actions on the assets. The pilot installation is scheduled for 2022 in an 800 kV substation.

SCAN

Frequency Domain Characterization and Analysis System to identify physical changes in high voltage electrical equipment. The virtue of this system is that it is composed of hardware and software that are easy to maintain, interchangeable with other technologies and low cost in the market.

The analyzes carried out with SMARTe and SCAN are important to the monitoring of the operational performance of equipment and installations in the Brazilian electrical system, reducing the possibility of failures that cause damage to people and/or other equipment and installations, in addition to interruption of the energy supply.

Fidcorr

Computer tool for automating the diagnosis of corrosion in foundations of transmission line towers, without the need for excavation or disconnection of the line, avoiding interruption in the energy supply. The use of Fidcorr contributes to systematizing and reducing the costs of the inspection process of transmission tower foundations. Combining an electrochemical technique with a computer program, FidCorr optimizes the maintenance of transmission towers to check and evaluate the progress of the corrosive process in these structures. In this way, the solution has the potential not only to increase average productivity in terms of towers inspected per day (from 3 to 12 towers/ay) but also in terms of towers inspected per day per employee, reducing the average size of the team required from 6 to 3 professionals.

2021 Highlights

GRI 103-1, 103-2, 103-3: Innovation for energy transition

In 2021, Cepel inaugurated new facilities, restructured or created internal areas and developed or completed various products and solutions in its laboratories. Some of these actions were particularly noteworthy, whether for the institution itself or among clients and the market. Some of them can be known below.

New Cepel Structure to align with the Sector's new challenges

Brazil has an already consolidated and growing role in the energy transition process to renewable sources: more than 85% of the national electricity matrix comes from clean and renewable sources, as well as 48% of the country's total energy matrix. With its mission to carry out research and development projects for the Eletrobras Companies and other companies in the electricity sector, Cepel works in the search for clean and renewable solutions for electricity generation companies, minimizing environmental impacts.

In 2021, we carried out important actions related to the energy transition. In the wind energy area, we develop projects for CGT Eletrosul and Eletrobras; in the field of photovoltaic generation, for Chesf and Furnas, which also demanded projects related to heliothermic generation; together with Eletrobras, projects were developed related to green hydrogen technologies, sustainability indicators and assessment of the environmental impacts of transmission lines.

The scenario of the Brazilian electricity sector has been of high demand in the areas of energy transition and energy storage, with the decentralization of generation plants, the creation of new forms of commercialization, digitalization and implementation of smart grids, and the growth of mobility based on electricity. Aware of this scenario, Cepel has carried out internal changes to ensure a relevant performance in the face of new challenges. Thus, in 2021, based on our Strategic Planning, we implemented structural changes, establishing four areas for the Technology Board: Energy Transition and Sustainability, Electrical and Energy Systems, Systems Automation and Asset Management Technologies.

The new Energy Transition and Sustainability area develops research lines and projects related to decarbonization, decentralization and digitalization, with a vision of research and development integrated with innovation and the bases of sustainable development, considering aspects of economic, social development and preservation of the environment. The expansion of renewable sources, combined with more efficient and sustainable forms of energy generation, is a critical factor for achieving long-term environmental goals, such as reducing greenhouse gas emissions and those agreed upon the national and international spheres. In this way, the area develops projects ranging from technologies such as solar photovoltaic and heliothermic energy generation, hydrogen, and energy storage technologies to projects in the field of carbon pricing, carbon and water footprint, climate change, indicators of sustainability, socio-environmental impacts of energy generation and methodologies and systems for energy and socio-environmental studies of hydrographic basin inventories.

As a result of the merger of the Development of Electric Grid Models and Energy Optimization and Environment areas, the Electrical and Energy Systems area works with models in the fields of generation expansion, energy operation, energy storage, water and wind resources, transmission reliability and generation, among others. The integration of those areas in this new structure brings greater synergy to the models used by the electricity sector, with data exchange between energy and electrical models, which, among other aspects, is fundamental for the adequate representation of intermittence and uncertainty of renewable generation sources. As a first result, the variation of reservoir drop height was implemented in dynamic models of generators based on the determination of this variable by energy optimization models. This implementation was fundamental to adapting the simulations in a dynamic regime to the realities observed in the field during the water crisis period.

The Systems Automation and Asset Management Technology areas work in a complementary way to develop programs that control and monitor electrical systems and their assets. Easily adapting to the constant growth of the electricity system, these solutions make it possible to support the physical expansion of agents networks and the growing complexity of assets and regulatory rules. Increasingly aligned with the innovative technologies of Industry 4.0 and the internet of things, several products widely used by companies in the sector – such as IMA-DP, SAGE, SOMA and DianE – are continuously updated and improved to adapt to new demands and technologies, producing control results that are always faster and more reliable, avoiding failures that could have great consequences and avoiding great costs, through the diagnosis of critical assets condition. These areas have developed a product capable of integrating the entire electrical control ecosystem, the GAMMA Architecture for Asset Management, which provides financial indicators for decision-making in maintenance tasks and the prioritization of investments in the replacement of assets based on the analysis of failure probabilities and financial risks. They also supply Elektra and CAMPEM products, which allow the analysis of the technical, economic, and environmental performance of transmission lines, substations, and high voltage installations in general, helping user companies in the diagnosis and prescription of measures that meet the needs of safety and socio-environmental legislation.

With this structure that allows the development of a variety of products and solutions, Cepel can present high efficiency and assertiveness in complex studies and diagnoses demanded by the electricity sector. More than 300 companies use our products and services. Our goal is to continue expanding our market, always serving customers with excellence.

Survey of laboratories and restructuring plan, aiming at integration

In 2021, in line with the reorganization of Cepel's cost structure in SAP to improve cost stratification and enable more effective management of its areas of operation from an economic and financial point of view, the Center's laboratories were organized into High Voltage, High Power, Calibration, Materials, Mechatronics and Structural Dynamics, and Energy Efficiency and Certification business units. Through their laboratories, the business units work in specific technical areas, namely: High Voltage, Extra-High Voltage and Ultra-High Voltage; High Power, High Current and Smart Grids; Chemistry, Corrosion, Metallography and Mechanical Properties; Mechatronics and Dynamics of Structures; Refrigeration, Lighting, Washing Machines, Electrical Machines and Transformers, Photovoltaic Systems and Electromagnetic Compatibility; in addition to certification of electrical and electronic equipment for hazardous areas and low voltage installation devices.

Cepel's laboratory infrastructure is a national technological heritage, with a large base of laboratories installed at the Center's origin, in the 1980s, maintained in the state of the art according to its applicability, as well as with new installations implemented over time - examples of which are the inaugurations of the Smart Grids and of the Mechatronics and Structural Dynamics laboratories, in December 2021.

Through its up-to-date infrastructure of laboratories and teams of multidisciplinary specialists, who work with technical excellence in different areas of knowledge in an integrated way, Cepel can provide complete and innovative solutions for the most varied and complex demands of the electricity sector, acting in projects that require experimental research; in technological services and tests, both in the laboratory and in the field and certification of products and services. Following national and international standards and technical specifications as requested by the client.

To improve its productivity and efficiency, the Center implemented the concept of dynamic teams in the laboratories through awareness-raising and training and has sought to optimize the use of its laboratory facilities, taking into account aspects such as:

• Complexity of the activity to be performed;
• The lowest O&M cost infrastructure available, with the requirements for the proper performance of the activity;
• Possibility of carrying out the tests by a batch of equipment, which makes it possible to reduce up to 80% of the total time for carrying out the tests.

Finally, in 2021 Cepel carried out a series of actions aimed at establishing strategic partnerships to expand market opportunities for the laboratories to operate, as well as continuing the activities defined in Agreements signed with Eletrobras within the scope of PAR/PROCEL - Annual Plan for the Application of Resources (PAR) of the National Electric Energy Conservation Program (PROCEL).

Methodology for Live Line Maintenance for Ultra-High Voltage Direct Current Systems (UATCC)

In 2021, Cepel completed the last stage of the Aneel R&D project “Development of Live Line Maintenance Methodology and Reliability Assessment under Pollution of Insulator Strings with Damaged Units for UATCC Transmission Lines – 800 kV,” carried out by Cepel along 32 months having State Grid Brazil Holding as a proposer. This is an intensive laboratory project, which was only possible due to the existence of the Cepel Ultra-High Voltage Laboratory infrastructure at the Adrianópolis Unit, and its team of specialists.

The initial stages of the project included laboratory tests to define the dielectric withstand of the insulator string used in 800 kV direct current transmission systems, under different conditions: clean, under pollution, with broken insulators and with the installation of the live line material. After obtaining this information, it was possible to reach the final goal: the definition of the methodology for replacing damaged insulators.

The infrastructure set up in the laboratory for the technique's transfer had a real suspension tower, representative of the one used in transmission at 800 kVdc, two glass insulator strings and 200 meters of six conductors bundle at each pole. In addition, a 40 m high lift platform, a drone and a camcorder were used to record the images. The work involved the discussion of the programmed activities and training at low height, using Cepel's High Voltage Tests under Pollution Laboratory infrastructure for the application of the insulator replacement tool. On the occasion, aspects of assembly and the electrician's positioning to carry out the activity were observed. Subsequently, the replacement of insulators was carried out in four different positions of the chain: the pole-side insulator, ground-side insulator, lower section insulator and upper section of the insulator chain.

With this activity, which is related to the obligation, under Law 9991, of investments in R&D by concessionaires, permissionaires and authorized companies in the Brazilian electric energy sector, Cepel fully achieves the project's objective by providing a practical and safe procedure to enable such important work for the reliability of Ultra-High Voltage Direct Current systems in Brazil.

Live line maintenance is applied to minimize the need for interventions to repair the electrical network with system shutdown. Before the results of this project, for interventions like these, it was necessary to reduce the power of the line and, consequently, stop offering the maximum power that Ultra-High Voltage technologies provide.

Adoption of DESSEM for price definition at the Electric Energy Commercialization Chamber

Adopted in 2020 by the National Electricity System Operator for scheduling the dispatch of the Brazilian electricity system on a semi-hourly basis, in 2021 DESSEM officially started to be used to determine the Difference Settlement Price on an hourly basis by the Electricity Commercialization Chamber. The calculation offered by DESSEM involves simulations performed between periods of up to two weeks, with intervals of up to half an hour, integrating the Newave and DECOMP models.

Diagnostics of high voltage substation equipment

Along the lines of the awarded IMA-DP, Cepel developed a system aimed at monitoring partial discharges to assist in the diagnosis of equipment in high voltage substations, such as lightning rods, instrument transformers, reactors, and power transformers. The new solution, entitled IMA-DP SE (substations), was implemented within the scope of the IMA Project, which integrates the portfolio developed in partnership with the Eletrobras Companies and aims to be a decision-making support tool for the management of equipment in operation in the National Interconnected System. The tests and validation of the IMA-DP SE were carried out in four major FURNAS substations of paramount importance for the Brazilian electricity sector: SE Brasília Sul, SE Samambaia, SE Brasília Geral, in Brasília, and SE Tijuco Preto, in Mogi das Cruzes.

Adoption of the SAGE platform by Cemig-GT

Cemig-GT, one of the most important generation and transmission companies in Brazil, now has the SAGE platform as an energy management system for its main and backup control centers. In 2021, in a challenging project, Cepel completed the migration of the previously used system to SAGE without interrupting the real-time operation functions. This is followed, in 2022, by the deployment of advanced tools for real-time network analysis and simulation for operator training.

Launch of the methodology for calculating the declared physical guarantee of wind farms

The estimated annual energy production of a wind farm in Brazil is calculated using different methodologies, available in commercial computational tools, which can offer a calculation with a 50% probability of being exceeded (called P50). This capacity does not meet the current requirement of the Energy Research Company, which requires estimates with a 90% probability of being exceeded (P90) to enable the venture to participate in auctions – this level is considered the physical guarantee of the wind farm. Thus, Cepel launched an unprecedented methodology for carrying out this calculation, aiming to reduce subjectivity in the estimation of uncertainties in energy production, which will be open to users making known the adopted hypotheses. With this, entrepreneurs and investors gain confidence in the calculation of P90 energy production.

Main laboratory technological services

Cepel Immersion

Conceived to increase the alignment of our projects and actions with the needs of the Eletrobras Companies, the event provided immersion in all the Center's areas of activity and greater interaction with the institution's technical staff. Its main objective was to contribute to the construction of the PI Portfolio, more aligned with the businesses of each of the companies, as well as to identify demands for technological services and other technical activities carried out by Cepel. The initiative is part of our market strategy and will be extended to other associates and customers.
