With the increasing role of distributed photovoltaic energy storage systems in power systems

the research on energy management and coordinated control strategies of optical storage microgrids becomes more and more important. First of all

research is carried out from the initial investment

operation and maintenance of the optical storage microgrid system

photovoltaic system power generation subsidies

grid power purchase costs

and power sales revenue to obtain the maximum economic benefit as the goal. Secondly

combining the time-of-use electricity price and load curve

a coordinated control strategy of optical storage power based on the peak-valley price difference is proposed. Finally

the optical storage microgrid system model is built in the simulation software to simulate the optical storage microgrid system at peak. The output characteristics of energy storage batteries under the valley electricity price difference mechanism verify the effectiveness of the power coordination control strategy based on the time-of-use electricity price mechanism proposed in this paper in the optical storage microgrid system
