| Summary: | This study presents an optimal control strategy for a load aggregator (LA) with demand response. The LA can provide consumers with time-of-use electricity price which could be different with the selling price of electricity by power grid. At the same time, LA has some distributed photovoltaic power generations, several diesel generators and energy storage devices to ensure user reliability and improve benefits. The LA's objective is to maximum its benefits without infringing the interests of consumers. A model of quadratical constraint quadratic programming is established to describe the above issues, and the generator-battery control strategy with demand response (DR) under optimal economic operation of the system is solved by CPLEX. The results show that the proposed management strategy and DR strategy improves the operational economy of the system.
