| Summary: | Voltage stability is a very serious concern in power systems because many equipment are connected to it; ranging from inexpensive one to a very expensive equipment. At distribution level trend nowadays, other kind of generation like Photovoltaic (PV) system, micro Combined Heat and Power (CHP) plants and wind turbines are connected to it. The purpose of this research is to study the behaviour of AC output of the grid connected solar photovoltaic (PV) during grid low and high voltage. The grid’s low/high voltage tests are conducted at three different period of time namely, morning, noon, and afternoon. This is because the irradiance and ambient temperature magnitude are distinctively different among these time zones. In the experiment it can be concluded that the output of solar is maintained at maximum level during the low and high voltage periods because the inverter’s Maximum Power Point Tracking (MPPT) algorithm reacted to ensure the maximum power is delivered to the grid. This is achieved through the current variation with respect to voltage change in maintaining maximum power. |
