System contributions of residential battery systems: New perspectives on PV self-consumption

France aims to boost the share of solar power generation in its electricity mix by 2030. When PV self-consumption systems become economically competitive, end-users will be willing switch instead using from grid. However, high penetration distributed provokes a significant impact on stability electricity. The major systemic issues concern seasonal back-up system associated with variable integration. Policymakers thus need work solutions (e.g. load management, peak shaving) support large-scale integration power. In this regards, study propose an innovative management model based secondary application residential batteries already installed for self-consumption. We performed prospective economic analysis identify potential contribution French PV-battery aim is reduce thanks collective use when they are not winter. A sensitivity has been conducted different projections 2030 (RTE, Enedis). Our then concludes key messages and policy recommendations.
