Research on Hierarchical Optimization Modeling and Scheduling Technology of Distributed Photovoltaic Cluster

The high density of distributed photovoltaic power generation has brought great challenges to the original economic and stable operation of the distribution network. In order to reduce the network loss caused by the access of distributed photovoltaic power generation to the distribution network and improve the economy of photovoltaic power generation, the concept and characteristics of distributed photovoltaic cluster are analyzed and summarized firstly. Then, according to the regulation characteristics of distributed photovoltaic power generation and reactive power regulation equipment in microgrid, a hierarchical optimal scheduling method with distributed photovoltaic cluster is proposed. Finally, the actual test system is used for modeling and simulation analysis under MATLAB mathematical software. The results prove the feasibility and effectiveness of the proposed optimal control method.
