iGREENGrid focuses on increasing the hosting capacity for Distributed Renewable Energy Sources (DRES) in power distribution grids without compromising the reliability or jeopardizing the quality of supply. Based on the experience of six world class DRES integration Demo Projects in low & medium voltage grids (led by some of EEGI members; Distribution System operators –DSOs-) and other EU initiatives in this field, the main final result will be a set of guidelines:
Most promising solutions, Recommendations for appropriate integration of small & medium size variable DRES in distribution grids, Methodologies and tools, Criteria to establish hosting capacity and to manage curtailment procedures, and Technical requirement to DRES, equipment manufacturers & technology providers iGREENGrid is the first analytical approach according to functional Demo Projects defined in the Roadmap and Implementation plan developed by EEGI. The assessment will include in the scope the following main functions:
DRES connection; Evaluation framework defined according EEGI KPIs; Distribution system balancing: ancillary services, operation criteria, reverse power flows and active demand management, storage, curtailing, smart metering; Signaling: data exchange with DRES and consumption, signals among sensors, metering; Simulation & Evaluation environment.
Strong coordination with EEGI, GRID+ project and other relevant initiatives will be established during the Project to receive appropriate feedback and to maximize the project impact. Beside, iGREENGrid encourages sharing knowledge and promoting the best practices identifying potential solutions in Demo Projects for the effective integration of DRES and validating them via simulation in other environments to assess the scalability and replicability at EU level (technical, regulatory and economic assessment).
