Description
The intermittent nature of renewable energy supply systems coupled with the variation in the terminal voltage supplied by these systems either due to variation of wind speed or solar irradiation makes it necessary to have an automated means of switching between these systems when the terminal voltage supplied by any one of them falls below a rated minimum value. The public utility can thus be regarded as a standby power supply systems which is only activated when both the solar and wind supply systems fail. This system coupled with the high solar radiation and the high wind speed of the Middle East and is capable of eliminating the need for public utility as inverters and battery systems can be used to provide backup power in the event of a failure of both renewable energy sources. This system provides an opportunity for the development of standalone power supply systems in rural areas without public utility. It also provides an opportunity for the minimal reliance on public utility by users in urban areas.
