Abstract:
In order to reduce the risk of distribution network operation, this paper calculates the power flow of distribution network based on the equivalent circuit diagram of distribution network, studies the calculation method of circulating current caused by loop closing operation of distribution network is studied, and puts forward a load control strategy to reduce circulating current, then uses the MATLAB/Simulink simulation software to build a simulation model of the operation of the distribution network, and the proposed control strategy to reduce the circulating current is simulated. The results verify the effectiveness of the proposed method.
