Research on Grid-connected Power Quality of Distributed Energy Storage Photovoltaic Grid-connected Based on Integrated Terminal in Distribution Network Area
In order to solve the power quality fluctuation problem of the grid-connected photovoltaic power generation system,a design scheme of photovoltaic energy storage grid-connected power quality system based on the integrated terminal in distribution network area was proposed.The basic framework of distributed energy storage photovoltaic grid connection is analyzed,and the basic parameters of power qual-ity monitoring are explained.The power management scheme of fusion terminal in distribution area is de-signed,which is divided into three schemes:fusion terminal with energy storage system power manage-ment,fusion terminal with energy storage PCS power management and fusion terminal with smart photo-voltaic disconnecting switch power management.The design of the battery energy storage PCS system il-lustrates the main technical principles of the smart photovoltaic disconnecting switch and the overall archi-tecture of the micro-application.Finally,the application analysis of the actual photovoltaic grid-connect-ed power grid in a certain area of China is carried out.
