Since the existing distribution network technology increases the active power loss of distribution network system,problems such an increase in the network loss value and a lower penetration rate will arise.To solve these problems,the research on the optimal control method for the flexible soft switch in distribution network considering demand-side response is proposed.First,a demand-side response model and an optimal control model of flexible soft switch are established.Then,the particle swarm optimization algorithm is used to solve these models,and the design of load transfer in distribution network is completed.Finally,the constraint conditions such as the operation of flexible soft switch,power flow in distribution network system and output from renewable energy power generation are set,thereby realizing the optimization of the control of flexible soft switch in distribution network.Experimental results show that after the application of the proposed method,the load of distribution network system can be effectively transferred,the active power loss of distribution network system and the overall network loss can be greatly reduced,and the penetration rate of distribution network system and the consumption of renewable energy power generation can be improved.As a result,the operation optimization of distribution network system is realized,providing a guarantee for its safe and economic operation.
