The volatility and intermittency of renewable energy output,and the stochastic uncertainty of customer power loads make energyscheduling for microgrids very challenging.Thus,to coordinate and optimize microgrid energy scheduling,a motivation dueling double deep Q-network(MD3QN)algorithm was proposed in this paper.Simulation analysis results demonstrated that the MD3QN algorithm for microgrids energy scheduling could obtain maximum economic benefit,and the peak shaving and valley filling of microgrids was achieved.Compared with the other four algorithms,the MD3QN algorithm had a higher composite performance.Therefore,the MD3QN algorithm was effective.
