Abstract: Now a days, photovoltaic (PV) system finds extreme interest as alternative source of energy and they are integrated with grids forming distributed generation (DG) systems. But, the output of PV system is dependent of irradiance and temperature. As these parameters changes location to location in a very unpredictable way due to weather and shading and also for some other reasons, it effects the overall performance of DG system. Here such three PV systems of each 255 KW was considered to be located in different locations. These PV systems feed power to the grid and acts like a DG system. But what if the insolation and temperature change in random behavior in these different locations and what will be their impact on the total system. The model was designed in PSCAD and the possible scenarios are considered and also the effect of it is analyzed. The comparison study is done with normal condition and varying condition. The study reveals the effect on PV, inverter and transformer output. The stability of overall system is affected and also harmonics are injected and also the differences in phase and amplitude are observed which degrades the system performance.
