Sugeno fuzzy logic control-based smart PV generators for frequency control in loop interconnected power systems
This paper proposes a smart photovoltaic (PV) generator equipped with the Sugeno fuzzy logic controller (SFLC) for load frequency control (LFC) in a loop interconnected power system. With high computation efficient and without time consuming in defuzzification, the SFLC is used to quickly control the AC power output of the PV inverter so that the system frequency deviation is alleviated. Since the solar insolation change and system frequency deviation are used as the input signals, the SFLC can suitably adapt its control performance. Simulation results in a three-area loop interconnected power system confirm that the PV with the proposed SFLC not only effectively alleviates the fluctuation of system frequency and tie-line power flow, but also supply output power near the maximum power point during frequency control. Besides, the control effect of PV with SFLC is superior to that of the PV with maximum power point tracking control under random solar insolations and load changes.
