Abstract : The rising demand for energy invites the contribution of renewable sources as alternative sources of energy. The major drawback of these sources is their inherently varying nature. They depend mostly on power converters for energy conversion and maximum power point tracking (MPPT). The increased penetration of such power converter based generation is degrading the stability of the existing grid, since synchronous generators based conventional energy generation is no longer capable of maintaining the grid stability. Synchronverter technology is a promising solution to this problem. To contribute to the stability of the system, here, synchronous machine dynamics is used to control the grid connected inverter. This paper aims to integrate a Solar Photovoltaic (SPV) system into the grid using synchronverter technology. It also reviews the modelling of the converter controller and analyses its performance under continuously varying input conditions. The capability of the converter to maintain synchronism under extreme conditions were also investigated. The results presented were based on a simulation study done in MATLAB/Simulink.
