Smart fuzzy logic control of photovoltaic system: case study Kingdom of Saudi Arabia

Robust controls of photovoltaic (PV) system applications that include modular multilevel inverter (MMI) for interfacing stand-alone and gridconnected operating modes are investigated in this paper to overcome problems two-level three-level inverters. The MMI provides high-quality voltage, current, power signals without additional filters, which reduces complexity cost interface circuits. A new control method active reactive has been introduced PV systems get maximum point (MPP) various climatic circumstances. steady-state dynamic performances using MATLAB/Simulink. fuzzy logic is proposed track the MPP utilizing perturb observe (P&O) technique. fair comparison between proportional integral (PI) was conducted controller obtaining MPPT by P&O fast accurate results. obtained results obvioused quick accessing than PI controller. simple LC filter can achieve minimum harmonics provided total harmonic distortion (THD) within IEEE limit. standalone grid-connected being tested under conditions city Tabuk, Kingdom Saudi Arabia (KSA).
