Advances in coordinated microgrid management

​In research conducted for the EU m2M-grid project, CEA-Liten, a CEA Tech institute, developed advanced microgrid coordination tools that were successfully tested on a real grid operated by electric utility SOREA.

​Microgrids produce, store, and distribute energy, generally at the scale of a neighborhood. These grids integrate advanced functions that enable them to operate either on the main grid, or independently if the main grid goes down. Plus, microgrids offer a wide range of advantages, like greater reliability, a more sustainable, higher-quality energy supply, and lower costs and transmission losses.

CEA-Liten developed innovative tools to coordinate grid management and ensure coherent interaction of grid subsystems. These tools are designed to meet the needs not only of individual microgrids, but also of transmission and distribution (T&D) grid operators. One of the goals of the project is to increase the penetration of renewable energy, of course. However, the tools developed will also support greater grid stability in virtually all operating conditions and help maintain sufficient voltage and energy quality to meet demand.

The coordinated voltage control (CVC) strategies and algorithms developed by CEA-Liten were successfully implemented on an actual grid. Sensors installed at a SOREA facility transmit real-time data on the status of the grid to the INES SCADA system. The data are used to calculate the CVC optimizations on site; commands are then sent to the solar switches and inverters at SOREA in real time.
