ČEPS Innovation Projects Respond to Changes in the Power Industry Environment

ČEPS, a.s., is implementing a variety of innovative projects focused on new solutions for to ensure the reliable operation of the Czech electrification system. As parts of the THÉTA program, which is conducted by the Technology Agency of the Czech Republic and dedicated to supporting research in the power industry, these projects include SecureFlex, MAFRI and Dflex, aimed at the topics of power flexibility, moderation and aggregation. The BAART research project deals with the topic of utilizing energy accumulation battery systems to provide power balance services.

“ČEPS has been active in the field of innovation, research and development for a long time. The need to innovate comes naturally from the fundamental changes of the present power industry environment,” says Karel Vinkler, director of the Innovation and R&D section of ČEPS.

SecureFlex, MAFRI and Dflex

ČEPS is already involved in project funded by the THÉTA program of the Technology Agency of the Czech Republic in the project draft preparation phases and remains active through to the implementation and wrap-up. In case of the SecureFlex and MAFRI projects, ČEPS, as the application guarantor, provides necessary or unique input, contributes its know-how, participates in the research method, pilots the output and provides feedback. This contributes to the subsequent utility of the project in practice.

“The THÉTA program is one of the tools that implements the state energy production concept, which makes it especially important in the research and development and eventual implementation of new technologies necessary to transform the Czech energy industry in relation to the technology changes that are currently underway. Connecting state subjects in the supported research projects, such as ČEPS, is a key part of the program implementation,” says Martin Bunček, the head of the office of the Technology Agency of the Czech Republic.  

SecureFlex and Power Flexibility

The energy sector is undergoing a series of changes that bring with them the need to innovate and look for means to ensure the reliable operation of the electrification system. As a result of the gradual transformation of the source mix, power flexibility (i.e., the option to alter power profiles on the consumer side) may eventually become one of the key stabilization tools in the future. The goal of the SecureFlex project is to create analytical, computational and optimization tools and targeted studies that contribute to the system of safe network utilization of power flexibility connected with the integration of new technologies and market subjects in the Czech environment.

The project includes detection areas and the quantification of power stability, the limits of its safe activation and algorithms of optimal activation of power flexibility, along with recommendations for legislative measures.

The SecureFlex project has been entrusted to the ZČU FAV NTIS consortium, the Masaryk University C4E and the Czech Institute of Informatics, Robotics and Cybernetics (CIIRC CTU).

MAFRI – Adequacy and Reliability of Power Policy

The goal of the MAFRI project (Mid-term Adequacy Forecast – Regional Indicators) is to develop new reliability characteristics that can serve as a basis for network operators and especially the responsible institutes (MPO). These characteristics can be used to make decisions regarding measures and investments at facilities that are at risk of insufficient power production. They will be helpful when choosing optimal solutions in terms of reliability and costs.

The requirement of production capacity adequacy evaluation is implied by the European Parliament and Council (EC) regulation No. 714/2009 on conditions for access to the network for cross-border exchanges in electricity. The results of the MAFRI project may be a contributing factor when making decisions regarding infrastructure investments and rectification measures with emphasis on the energy self-sufficiency of the Czech Republic.

The project adapts the current and develops new reliability characteristics for the Czech electrification system in the context of the Europe-wide system. It utilizes and expands the indicators based on the Mid-term Adequacy Forecast, localizes the reliability indicators for power supplies at given times and places, in the volumes and durations of detected production capacity deficiencies. The output of the project will include a methodology for adjusting reference (critical) values of reliability characteristics in order to reflect the power shortage risks and impact of shortages on specific consumer groups or civil units with maximum reliability. It will also include the methodology to compare the indicated power shortage risks to individual rectification alternatives.

MAFRI has been entrusted to a team of power industry specialists from the Department of Intelligent Systems at the Czech Institute of Informatics, Robotics and Cybernetics (CIIRC CTU).

Dflex and Aggregation

The Dflex project is implemented in collaboration with the Czech Institute of Informatics, Robotics and Cybernetics (CIIRC CTU), Pražská Energetika and Digital Energy Services. ČEPS assumes the role of the main recipient, and the Ministry of Industry and Trade is the application guarantor. The goal of the project is to verify the option of active involvement of small sources, thus providing flexibility for the operation and control of the electrification system, and subsequently using aggregation and active decentralized control systems to transform the production of those sources into products usable for system stabilization. The project will involve assessment of system requirements, definition of terms for aggregator access to the flexibility market and creation of algorithms for evaluation of provided flexibility and delivery management.

“The main contribution of the project is to verify the applicability of the flexibility aggregation in the conditions of the Czech power industry in the initial concept phase. The implementation of this project will bring the knowledge and experience necessary to introduce the aggregation into practice within the time horizon required from the Czech Republic by the European commission,” says Karel Vinkler.

The BAART Research Project and Accumulation

The gradual development of battery system accumulation of energy (BSAE) technology brings with it the potential to use this technology in the provision of supporting services, specifically in the category of power balance service (SVR). As the operator of the Czech distribution system, ČEPS has been using SVR to control the differences between power production and consumption via altering one or the other. Looking to test BSAE in power balance serviced under the conditions of the Czech electrification system and real operation, ČEPS and ČEZ have been conducting the research project named BAART.

The primary purpose of this project, which utilizes a 4 MW battery located in the Tušimice power plant, is to create, adjust and modify the services of the BSAE power balance and even more importantly the practical verification thereof. The pilot operation of BSAE will involve testing the individual modes of frequency control, the quality of provided services and charging strategies.

“Fundamental changes to the power sector bring with them the development of new technologies, as well as the need to adjust the conditions of their integration into the Czech electrification system. The implementation of the BAART research project allows us to deepen our present knowledge on the integration of battery systems into the power system under the conditions of the Czech electrification system with regards to providing support services,” says Svatopluk Vnouček, deputy chairman of the board of ČEPS responsible for strategy, innovations and development of the distribution system.

Innovation, Research and development in ČEPS

ČEPS’s research and development priorities are defined on a long-term basis and are based on the Company’s medium-term strategy. In the field of research activities, ČEPS has been conducting numerous projects and studies, both on their own or in collaboration with other subjects in the Czech Republic and abroad. ČEPS has been actively involved in work associated with the NAP SG plan coordinated by the Czech Ministry of Industry and Trade. ČEPS is also an active member of the Sustainable Energy Technology Platform (TPUE), where research topics concerning the Czech electric power sector are discussed and prepared.

The company is represented on the Research, Development and Innovation Committee under the ENTSO-E association. The main mission of this committee is the preparation of drafts for projects dealing with electricity transmission on the European scale.
