Brunner H., Martini L. An European Integrated Research Program on Smart Grids and the ELECTRA Web-Of-Cells Concept
The electricity grid plays an important role to achieve Europe's 2020 and 2050 targets and visions on greenhouse gas emissions, renewables and energy efficiency. To foster related research the European Energy Research Alliance (EERA) organized a Joint Research Programme (JP) on Smart Grids (SG), involving 40 research organizations from 17 different European countries. The EERA JP SG addresses a medium- to long-term research perspective for the effective acceleration of smart grid development and deployment. The ELECTRA Integrated Research Programme (IRP) is one of the operative tools of the EERA JP SG promoting new control solutions for the 2030 power system real-time operation, utilizing flexibility from across traditional boundaries (e.g. voltage level, stakeholders). This paper introduces the ELECTRA IRP and the proposed decentralized control scheme for reserves activations in the future (2030+) power system. The ELECTRA Web-of-Cells concept, based on splitting the power system into a web of subsystems, or cells, is following the paradigm of solving local problems locally. It is focusing on local inter-cell tie-line power flow deviations – comparable to the well-known Area Control Error, but at cell level– rather than system frequency, where the responsibility for detecting and correcting such real-time deviations is delegated to local (i.e.cell) operators. Obviously, local voltage problems will become more important as well, and must – due to their local nature – be dealt by a local operator anyway. The paper describes in detail the Web-of-Cells concept and the associated control scheme.
