摘要

The random access of the microgrids (MGs) to distribution network and disordered operation will result in high network loss. Aiming at this problem, a double-loop cooperative optimization strategy for optimizing network loss is proposed. This strategy builds an optimization model based on MGs with electric vehicles (EVs) and renewable energy sources (RES). The inner-loop model reconfigures the network structure of MGs through optimization to reduce the basic network loss of the MGs. The outer-loop model optimizes the node location of the MG accessed to the distribution network in the MGs to reduce the increased network loss of the MGs. The inner-loop and outer-loop synergistically reduce the total network loss of the MGs. Particle swarm optimization (PSO) is used to solve the model. Finally, four simulation cases are used to prove the rationality and feasibility of the proposed strategy.
