In this paper, reactive power adaptive control system of photovoltaic inverter for stable operation of distribution network is studied. This paper presents an adaptive hysteresis control algorithm for grid-connected solar photovoltaic inverters to improve the stability and response speed of grid-connected solar photovoltaic systems. Based on the hysteresis control mathematical model, the algorithm dynamically adjusts the hysteresis control threshold and bandwidth through real-time monitoring and analysis of the photovoltaic array output power, to achieve accurate reactive power control. In order to verify the effectiveness of the proposed algorithm, a simulation model of grid-connected PV inverter system is established in MATLAB/Simulink environment and a detailed simulation experiment is carried out. The simulation results show that the proposed adaptive hysteresis control algorithm can significantly improve the dynamic response speed and steady-state accuracy of the system, effectively reducing the fluctuation range of reactive power, and thus improving the stable operation level of the distribution network. This study provides a new idea and method for reactive power control of grid-connected photovoltaic inverters, which is of great significance for promoting the development of solar photovoltaic power generation technology.
