Abstract :
This paper presents maximum power point tracking (MPPT) simulation for a photovoltaic (PV) system. The MPPT is used to find and maintain operation at the maximum power point. Algorithm used is perturb and observe (PO). There are four blocks in this simulation i.e. PV, boost converter, hysteresis PWM, and PO algorithm. The output of PO algorithm block is reference voltage. Hysteresis PWM block generates switching pulse for IGBT in boost converter that regulate PV output voltage tracks reference voltage. The simulation is carried out by PSIM. Simulation result show that PO algorithm can find and maintain operation of PV at maximum power point. The increase in irradiation causes PV power generated will be increased. But the increase in temperature will cause the generated PV power decreased slightly.
