Research on application of photovoltaic-energy storage micro-grid in 500kv substation station power system

Traditional substation station power are taken from the grid system, power consumption is relatively large, not only increases the power loss, but also the consumption of nonrenewable energy. With the development of micro-network technology, more power users tend to use the new micro-grid power supply mode to improve power supply reliability. In this paper, the power supply system of 500kv substation in Leezhou is taken as an example, and the scheme of using optical storage micro-grid system as supplementary power supply for UHV station is designed respectively. The distributed power capacity and energy storage System capacity for joint solution, while optimizing the configuration.
