An EU team addressed the issue of renewably sourced bidirectional power flow on electricity grids. The study recommended management solutions in low- and medium-voltage networks, in order to provide additional services and reserve capacity.
The rise of distributed renewable energy sources (DRESs) places the secure operation of national electricity grids under great strain. The problem is bidirectional power flow, which electricity suppliers must control in order to provide service at acceptable quality and cost.
