Coordination control method of photovoltaic and energy storage for distribution network based on virtual substation

In view of the low reliability of power supply in rural distribution network and the problem of voltage overrun and power flow reversal caused by large-scale distributed photovoltaic access under the policy of photovoltaic poverty alleviation, a coordinated control method of optical storage based on Virtual Substation mode is proposed. Combining with the actual engineering case of Yinglixiang distribution network in Hebei Province, the steady-state performance of the system under different operation schemes, such as voltage level and network loss, is analyzed. The effectiveness of the proposed method to improve the reliability of rural distribution network is verifed by Monte Carlo simulation.
