Abstract

Use of photovoltaic (PV) panels in power generation is the most widely used renewable energy source today. But this solar power energy source is highly susceptible to fluctuations and easily affected by variations in weather conditions over the area. At such times, solar forecasting models play a key role for operators to manage the operations of generation units such as balancing the fluctuations and extracting, supplying and maintaining maximum output power. Maximum Power Point Tracking (MPPT) technique is the technique offently preferred in photovoltaic (PV) systems to extract the maximum power inspite of climatic variations. In this paper various solar forecasting methodologies are discussed. Out of the various MPPT methods, the perturbation and observation (P&O) method is widely used.
