Application Model of Photovoltaic Energy Storage System in Rural Low-voltage Distribution Network

Photovoltaic power generation is environmentally friendly and easy to maintain. It can effectively suppress its random fluctuation characteristics and eliminate the peak-to-peak difference between day and night by using energy storage technology. It provides technical support for solving power supply reliability problems in remote rural areas. This paper introduced the current status of the operation mode of the optical storage model in the power system at home and abroad, and studied the application mode of the photovoltaic energy storage system (PESS) in the rural low-voltage distribution network from the aspects of grid investment, user investment, third-party investment, and shared investment. The storage model provides feasible ideas for the promotion and application of low-voltage rural power grids.This work is supported by Science and Technology Project of Guangdong Power Grid Co., Ltd.
