Forecasting methods used for performance's simulation and optimization of photovoltaic grids

The energy-efficiency statistical model presented below is an acceptable and quickly method of photovoltaic grid behavior forecasting, for specific photovoltaic energy producing application. Using the standard method of efficiency evaluation, a statistical model for photovoltaic grids is proposed, transposing collected data in the specified model pattern of the exponential smoothing and autoregressive integrated moving average statistical techniques. These aims were included in a prospective software program (EnergOptimizer), which provide advanced features of designing, forecasting and three-dimensional shading prediction tool. Therefore, a systematic analysis of the photovoltaic grids, in energy-efficiency respect, following this conception will bring benefits in the simulation and optimization background of photovoltaic projects.
