Hybrid microgrid system is regarded as the part of the core network of electricity system and can also be separated alone from the main grid. According to the load fluctuation such as from 150kW to 250kW and from 250kW to 200kW, the modeling and simulation of a standalone hybrid microgrid system with photovoltaic, wind and battery is analyzed in this paper. For the photovoltaic system, PV array which has total numbers of 580 PV modules is connected with a boost converter. In order to obtain the maximum amount of power from PV array, the Maximum Power Point Tracking (MPPT) technique is used. In the wind energy system, a permanent magnet synchronous generator (PMSG) is with the d-q reference frame used. The wind energy system control is determined by using the Maximum Power Point Tracking (MPPT) technique to obtain the maximum power from continuously varying wind speed. Battery is used as the energy storage device to absorb excess of power and cover shortage of power. The proposed standalone hybrid microgrid system performance is carried out with MATLAB Simulink simulations under standard test condition in which 1000w/m2 radiation, cell temperature 25? and wind speed is 10m/s.
