The electric power supplied by a photovoltaic power
\r\ngeneration systems depends on the solar irradiation and temperature.
\r\nThe PV system can supply the maximum power to the load at a
\r\nparticular operating point which is generally called as maximum
\r\npower point (MPP), at which the entire PV system operates with
\r\nmaximum efficiency and produces its maximum power. Hence, a
\r\nMaximum power point tracking (MPPT) methods are used to
\r\nmaximize the PV array output power by tracking continuously the
\r\nmaximum power point. The proposed MPPT controller is designed
\r\nfor 10kW solar PV system installed at Cape Institute of Technology.
\r\nThis paper presents the fuzzy logic based MPPT algorithm. However,
\r\ninstead of one type of membership function, different structures of
\r\nfuzzy membership functions are used in the FLC design. The
\r\nproposed controller is combined with the system and the results are
\r\nobtained for each membership functions in Matlab\/Simulink
\r\nenvironment. Simulation results are decided that which membership
\r\nfunction is more suitable for this system.<\/p>\r\n","references":"[1] J. Applebaum, \u201cThe Quality of Load Matching in a Direct coupling\r\nPhotovoltaic System \", IEEE Trans.
