Load Power Tracking Control of PV Cells Based on Integral Adjustment Algorithm
With the widespread application of photovoltaic power generation systems and microgrids,the problem of mismatch between photovoltaic generation power and load rated power is becoming increasingly prominent when operating in isolated mode.A load power tracking control strategy for photovoltaic cells based on integral adjustment algorithm was proposed by studying the output power characteristics of photovoltaic cells.In the island mode,the output power of the photovoltaic power generation system can automatically track the rated power required by the microgrid load within the capacity range,thus meeting the requirements of power balance in the island operation mode of the microgrid.Finally,the feasibility of the proposed control strategy was verified through the construction of a dynamic simulation experimental platform for a photovoltaic microgrid with a rated power of 100 kW.The research results obtained can provide technical reference for using solar power generation to solve the stability problem of load power supply in areas without electricity.
