BATTERY STORAGE INFLUENCE ON ELECTRIC SYSTEMS WITH EMBEDDED RENEWABLE: A TECHNOLOGY OUTLOOKFOR ROMANIAN POWER NETWORK IMPROVEMENT

Abstract

High penetration of variable renewable energy sources (especially wind and solar) in electrical grids rises o series of balancing and regulating issues. One of the most important one is the need for increase of grid flexibility. Battery storage systems represent a mature technology for enhancing grid flexibility by managing electricity supply fluctuations both at electrical systems and insulated week grids.This paper analyzes the influences of this technology from technical point of viewto an international level, conclusions referring to the Romanian national grid level being drawn at the end.
