Voltage Coordination Control Strategy for Distributed Optical Storage Systems in Low Voltage Distribution Networks
In order to solve the problem of voltage exceeding limits in distributed optical storage systems in low-voltage distribution networks,this paper conducts research on voltage coordination control strategies.Firstly,establish a distributed optical storage system grid connection model.On this basis,a voltage control strategy based on the remaining capacity of the photovoltaic inverter,a control strategy for energy storage par-ticipating in voltage regulation,and a voltage control strategy for coordinating the photovoltaic inverter and energy storage are proposed.Finally,analyze the application effects of three control strategies.Analysis shows that the new control strategy is effective in practical applications,which can solve the problem of voltage ex-ceeding limits and improve the stability of low-voltage distribution network operation.
