The results show that the optimized photovoltaic and energy storage system can effectively improve the photovoltaic utilization rate and economic of the microgrid system. The model can provide an effective method for the design of photovoltaic and energy storage configuration schemes for microgrids in rural areas. 1. Introduction
The optimal configuration model of photovoltaic and energy storage is established with a variable of the energy storage capacity. In order to meet the optimal economy of photovoltaic system, reduce energy waste and realize peak shaving and valley filling, the economic index and energy excess percentage are included in the objective function.
According to the analysis of the distribution of renewable energy in rural areas, a typical photovoltaic microgrid power supply system is established as shown in Fig. 1. The microgrid includes a photovoltaic power generation system, energy storage devices, rural industrial loads, rural agricultural loads and rural resident loads. Fig. 1.
The popularization of photovoltaic microgrid mode can reduce the dependence on fossil resources, and has significant energy saving and environmental protection benefits, , . The power grid in rural areas has the disadvantages of weak grid structure, scattered load and large peak-to-valley difference.
Firstly, we construct a spatial-temporal dynamic distribution model of rural EV charging load coupled with distribution network - transportation network, and on this basis, we consider the
