Stand-Alone Solar PV System using MPPT Technique in Simscape

Abstract


the stand-alone solar photovoltaic (PV) system mostly used by the islanded power electricity needed for rural area that located far away and unreachable from the national grid. Due to operate the system, the multiple power point tracker (MPPT) technique is used to support PV system to operate at its maximum power. The way the MPPT algorithm works is by calculating the output of PV module, then compares it to battery voltage then fixes what is the optimum power that PV module can produce to charge the battery and converts it to the optimum voltage to get maximum current into battery. It can also supply power to a DC load, which is connected directly to the battery. MPPT is very useful in cloudy days. This paper deploys the use of MPPT technique within the stand-alone solar PV system by simulating the designed Simscape model. Two MPPT techniques, which are the incremental conductance and perturbation and observation (P&O) have been chosen to be run as the system simulated. The parameters that have been observed are DC bus voltage, the PV power, the PV voltage, and the PV current, respectively. The results showed that the DC bus voltage raised and steady at the 377.3 V, the solar power increased to 2 kW, and the PV current decreased to approximately 7 A. The DC load is connected across the boost converter output. The solar PV system operates in both maximum power point tracking and de-rated voltage control modes. To track the maximum power point (MPP) of the solar PV, the two MPPT techniques incremental conductance and P&O might have been chosen.
