A Method to Estimate the Yield of Photovoltaic Power Plant Solely in MATLAB/Simulink

The Yield of photovoltaic power plant grid-connected depends upon seasonable variation of solar radiation, system loss, soiling loss, and loss of inverter. This paper presents a method to estimate the yield of photovoltaic power plant solely in MATLAB/Simulink. The yield of photovoltaic power plant grid-connected has been developed based on the photovoltaic model, loss model. In this case, the 1MW solar power plant connected in the grid in three locations in Vietnam have been simulated with the weather season variable and compared with PVGIS software. From the result, the total yield of photovoltaic power plant connected into the grid is range 1180.16 to 1247.42 MWh/Year with the losses system is 28% including losses of system and irradiance losses. Furthermore, the gap between this systems compared with PVGIS software is range -1.47 to 4.64 MWh/Month.
