Abstract

A grid-connected photovoltaic power system in-loop real-time simulation platform based on a virtual synchronizer comprises three portions consisting of an upper computer, a PXI real-time simulation system and an external measurement controller. The upper computer is connected with the PXI real-time simulation system and the external measurement controller through an Ethernet, and the PXI real-timesimulation system is connected with the external measurement controller through an I/O interface. The grid-connected photovoltaic power system in-loop real-time simulation platform based on the virtual synchronizer can rapidly develop and verify a control strategy in a laboratory environment, can simulate operation features of a photovoltaic array and can allow the controller to achieve comprehensive closed-loop verification prior to actual condition test so as to greatly save the test cost, shorten the development period, improve the operation safety and provide a basic research platform forthe virtual synchronizer control technology research and development and the optimization control of the grid-connected photovoltaic power system.

Description

technical field [0001] The invention relates to renewable energy grid-connected power generation, in particular to an in-loop real-time simulation platform for a photovoltaic grid-connected power generation system based on a virtual synchronous machine. Background technique [0002] With the depletion of fossil fuels such as oil and coal and the increasing environmental pollution, energy crisis and energy pollution have become the main problems facing human society. The development of renewable energy such as photovoltaics and wind power has become an effective means to solve this problem. Among them, photovoltaic power generation has become the main form of renewable energy power generation due to its unique characteristics. However, unlike traditional synchronous generators, photovoltaic power generation converts the direct current generated by the photovoltaic array into alternating current through an inverter and sends it to the grid. It does not contain rotating elemen...
