摘要
构网型光伏表现出电压源特性,可以在弱电网中稳定运行.本文提出一种基于直流电压同步的构网型光伏控制策略,分析了光伏并网变流器利用直流电压按照构网型控制策略运行的原理.基于直流电压同步的构网型控制策略可以使光伏工作在最大功率点.最后通过控制器硬件在环实验验证了所提控制策略的有效性.
Abstract
The grid-forming photovoltaic exhibits voltage source characteristics and can operate stably in the weak grid.A grid-forming photovoltaic control strategy is proposed based on the DC voltage synchronization and analyzes the operation principle of the grid-connected photovoltaic converter utilizing DC voltage to operate in the grid-forming control strategy mode.The grid-forming control strategy based on the DC voltage synchronization allows the photovolta-ic to operate at the maximum power point.Finally,the effectiveness of the proposed control strategy is verified by con-troller hardware-in-the-loop experiments.
