A Microgrid Optimization Method That Comprehensively Considers Demand Response and New Energy Consumption

In view of the difficulties faced by the consumption of new energy and the problem of flexible dispatch of high proportion of renewable energy into the distribution network, this paper first considers the complementarity of multiple energy sources, and establishes a model for the subsystems including wind, solar, diesel and storage energy by combining wind energy, solar energy and local load in the microgrid. Secondly, in view of the uncertainty of the user-side operation of the microgrid system, the price demand response (DR) mechanism is introduced, and the strategies of interruptible load, transferable load, and translational load are used to respond to the peak regulation problem caused by the new energy access to the power grid. Then, the minimum cost and the maximum renewable energy utilization efficiency are taken as the objective functions and their constraints are determined. Finally, the Pied kingfisher optimizer(PKO) with chaotic motion and adaptive weight improvement is used to solve the multi-objective, and the final optimization results are obtained.
