This project intends to study the coordinated optimization control of distributed photovoltaic power generation and reactive power based on the optimal voltage source. First, a two-level mathematical model consisting of a distributed photovoltaic grid-connected system, a gridconnected inverter and a reactive power compensation unit was established. The high-level model uses a global optimization method to conduct an overall design and design of the coordinated control of grid-connected photovoltaic power generation and reactive power; the low-level model accurately adjusts the system based on the instructions of the high-level model and in connection with the actual operating conditions of the power system. The two-layer structure can ensure the overall optimality while maintaining local flexibility and realtime performance. This project proposes a new fuzzy adaptive PI control method that can adjust the controller parameters as the grid operation and external conditions change, to achieve the purpose of coordinated control of photovoltaic grid connection and reactive power regulation. This method has good dynamic performance and stability under the premise of ensuring dynamic performance.
