MPPT Simulation of Cluster Photovoltaic Power Stations for New Power System Planning

Under the background of peak carbon dioxide emissions and carbon neutrality, the new power system has been developed rapidly. With the development of new power systems, more and more photovoltaic power generation will be connected in the future. It brings new challenges to the planning of the power system. In order to improve the voltage gain of photovoltaic power generation systems, this paper proposes a maximum power point tracking method (MPPT), which is applied in the front-end DC/DC boost circuit. And propose a constant DC voltage constant reactive power inverter control applied in the back-end DC/AC inverter circuit. It controls the maximum power point voltage of the photovoltaic power generation system by adjusting the conduction duty cycle of the Boost switch. This technology can improve sensitivity while ensuring reliability. The final example verifies the effectiveness of the proposed method.
