【 摘 要 】

In spurring towards a lower-carbon and renewable energy dependent future, this paper considered the requirements of the Malaysian climate and transmission network in designing a system that extracts maximum power from photovoltaic (PV) and provides AC source-side reactive power compensation. In modelling a system appropriate for energy demands of Malaysia, solar irradiance is varied from 1.25 kW/m2 to 5 kW/m2 and temperature between 25°C and 50°C. An average simulation model is first designed, incorporating the control elements demonstrated by the selected maximum power point tracking (MPPT) algorithm and static synchronous compensator (STATCOM) control scheme for balanced loading conditions. To justify the results obtained, a second detailed model is designed to account for inclusion of harmonics. Power factor of 0.8 was employed for the average and detailed models before the providence of reactive power compensation. Ultimately, both simulation results obtained were consistent with each other, thus validating the robustness of the system in maximum power extraction and reactive power compensation even under varying solar irradiance and temperature.
