摘要
Abstract
Grid current with single closed-loop control is one of the effective means to the photovoltaic(PV)grid-connected inverter.However,it also results in issues of low control precision and poor stability.A hybrid grid current instantaneous value control method with PI control and repetitive control was carried out as the outer loop,and the LCL filter capacitance current instantaneous value control method with PI control which could improve damping as the inner loop of the double closed loop control strategy was proposed.The hybrid control algorithm was simulated by Matlab/Simulink,and a 6 kW inverter was built to verify the system′s effect.Simulation and experimental results verifiy that the control strategy not only improre the dunamis performance,but also improve the stability precision of the system.关键词
