Abstract:

This paper proposes an intelligent control technique using a fuzzy logic controller (FLC) to obtain the maximum available power of PV module under unstable conditions. Control of the presented system is based on instantaneous power theory (p-q theory) and adaptive hysteresis band control (AHBC). According to this strategy during sunlight the system sends active power to the grid and at the same time compensates the reactive power of the load. In case there is no sunlight the inverter only compensates the reactive power of the load. Variable switching frequency due to fixed hysteresis bands known as a drawback of hysteresis method used in power system applications. To solve this problem, adaptive hysteresis current control (AHCC) has been introduced. Simulation results using MATLAB/SIMULINK verifies effectiveness of the system in injecting of maximum power and compensating of the harmonic currents and reactive power of the nonlinear load.
