Abstract

Rooftop distributed photovoltaic （PV） has been widely used as a power source for "self-generation" and "surplus online", and with the strong support of national policies, PV power generation technology and energy storage technology are gradually becoming a major industry. First, this paper starts from the support policy and pilot application of rooftop distributed PV, and then proposes the core technologies of energy storage in the development of rooftop PV for the whole county system according to the analysis of the current problems of rooftop distributed PV development： scenario generation and evaluation of rooftop PV and energy storage, coordinated power generation control of rooftop distributed light and storage system, economic efficiency, convergence technology, and rooftop distributed PV security technology. Finally, the outlook on future rooftop distributed PV and energy storage technologies is carried out which provides suggestions for the development of rooftop PV and energy storage industries in China.
