摘要
Abstract
This study establishes a simulation model of singlephase gridconnected photovoltaic non-scheduling system by using Matlab software. This model includes photovoltaic module, dcdc power converter, PWM inverter and its current hysteresis feedback control, maximum power point tracking （MPPT） module, and phase-locked loop （PLL） module. Then PV system with and without gird connected are simulated and analyzed.关键词
