A synergistic operation optimization model with supply and demand sides considered for micro-grid(MG)containing household cluster loads was proposed in this paper.The model was composed of demand response(DR)optimization and MG optimization.In the DR optimization,time-of-use price was utilized to guide users to regulate loads and participate in DR,energy consumption behavior was improved and demand curve was optimized on the basis of meeting the daily electricity demand.In the MG optimization,DR and supply side resources were synergistically optimized as a whole,output power of distributed energy resources and grid-connected interactive power were optimized based on the interaction balance between supply and demand to minimize the integrated operation cost of MG.Binary particle swarm optimization algorithm was used to solve the model.The simulation results of system calculating example showed the effectiveness of the proposed model.
