Optimal capacity configuration of photovoltaic-storage microgrid considering flexible load

Under the background of continuous growth of renewable energy penetration and continuous transformation of energy industrial structure, how to effectively balance photovoltaic consumption and economic benefits of power grid has become an important challenge for the future development of new power system. Based on the perspective of improving photovoltaic consumption capacity and reducing the comprehensive cost of power system, this paper proposes a capacity configuration method of photovoltaic-storage microgrid considering flexible load response. An optimization model of optical storage capacity with the goal of minimizing the total annual cost of optical storage microgrid is established, and the constraints of flexible load response, user satisfaction, power balance and energy storage operation are comprehensively considered for example simulation. The results of the example show that considering the flexible load response can effectively improve the economy of the optical storage microgrid and enhance the flexible adjustment ability of the system.
