To address the issue of significant energy loss due to the mismatch in power generation methods following the integration of new energy sources into the power grid,this paper proposes a method for controlling energy loss.Based on the calculation results of distribution network losses,the paper analyzes the factors affecting unexpected energy loss when new energy sources are connected.It then obtains the optimal control objective function for energy loss in the distribution network,establishes control constraints,and constructs an optimal control model for energy loss in the distribution network.The particle swarm optimization algorithm is utilized to solve the control model,obtaining the optimal control value of electrical energy loss,and thus achieving the electrical energy loss control of the distribution network under new energy access.The experimental results show that using this method for power loss control,the loss of active and reactive power at the head of the transmission line can be controlled within the expected range.
