In recent year's renewable energy sources have become a useful alternative for the power generation. The power of photovoltaic is nonlinear function of its voltage and current. It is necessary to maintain the operation point of photovoltaic in order to get the maximum power point (MPP) in various solar intensity. Fuzzy logic controller has advantage in handling non-linear system. Maximum power ...

Recent advancements in photovoltaic (PV) system technologies have decreased their investment cost and enabled the construction of large PV farms for bulk power generations. The output power of PV farms is aaected by both failure of composed components and solar radiation variability. These two factors cause the output power of PV farms be random and diierent from that of conventional units. The...

The stability of power production in photovoltaics (PV) power plants is an important issue for large-scale gridconnected systems.
