光伏市电互补系统建模及其运行特性
Modelling and Operation Characteristics of Photovoltaic-Grid Complementary System
摘要
Abstract
Dynamic analysis model of the photovoltaic-grid complementary system is established in this paper.Maximum power point tracking method based on variable step without input-voltage detection and control strategy based on reverse blocking diode control DC bus entrance are proposed.Comparing with the disturbance observation method,the effectiveness of the maximum power point tracking method proposed by this paper is proved.Simulation results of the photovoltaic-grid complementary system verifiy the effectiveness of the model.The fluctuation characteristic of the load current and voltage are tested.Experimental results further show that power supply switch from photovoltaic to grid automatically when solar radiation reduces.In the process of the power switch,distortion rate of the load voltage and current is small and system running smoothly.Realizing the purpose of using photovoltaic generation in real time and in place to dissolve.关键词
