The reliability assessment of central photovoltaic inverter in electric power system

The electric power system produced by Photovoltaic (PV) system is being gradually utilized in power system network with different Photovoltaic configuration. The central Photovoltaic inverter system is designed in large scale of solar power. This system has a different impact on system reliability than conventional generation due the intermittent nature of geographical locations and the availability of PV electronic system. It is therefore vital to evaluate the reliability contribution of central PV system in electric power system network taken into account entire PV system components. This project uses a probabilistic and Part-Count approach to develop the output power of central PV system. A developed model is then applied to Small Isolated Power System (SIPS) to study the system adequacy and the capacity credit of installing Photovoltaic units.
