Synchronverter based photovoltaic inverter

摘要

We present a research of a possibility of constructing a photovoltaic DC to AC inverter based on a synchronverter operation principle. A possible area of an application for this inverter is in a photovoltaic power plant that is connected to the low voltage grid. We give a brief explanation about a theoretical control algorithm that governs an operation of the inverter including Maximum Power Point Tracking (MPPT). A Simulink average model verifies the performance of the algorithm. We also present a brief explanation of the experiments that are in progress in Smart Grid Interoperability Laboratory of the European Commission Joint Research Center in Ispra, Italy. The main goal of these experiments is to verify a performance of the control algorithm by using an external PCB uploaded with the control algorithm and connected to the Real Time Digital Simulator (RTDS).
