A Review of the Optimal Configuration of the "PV-Energy Storage-Direct Current-Flex" System

In the context of large-scale new energy applications and "carbon peak" and "carbon neutrality", Photovoltaic power generation because of its clean and easy large-capacity storage characteristics. It can improve the utilization rate of new energy and the stability of power system operation, and further reduce carbon emissions, so photovoltaic power generation has become one of the future energy sources that are vigorously developed. The capacity configuration model and solution method are the focus of the current research. This paper summarizes the research status of optimal scheduling of integrated energy systems from two aspects: scheduling model and method. According to the difference of research priorities, the basic optimal scheduling model and the optimal scheduling model considering the randomness of the system are discussed respectively. The solution methods are divided into analytical method and artificial intelligence method. Finally, a vision for the future is put forward based on the existing problems.
