PV, battery storage and energy conversion system for meeting peak load in a substation

Out of firm (OOF) conditions at a distribution substations may last for several hours and it is quite common in a rapidly growing distribution system like the one at Kahramaa (Qatar). Dealing with such a condition is a big challenge for network planners. Combination of renewable, power electronics and advent of more efficient storage systems can give innovative solutions to similar challenges. This paper describes a methodology of using energy storage system, including photo voltaic and battery storage, to provide energy during the peak hours of the day to avoid N-1 violation of reliability criteria. The methodology would be implemented at a selected substation, and the implementation process is also outlined in the paper. The application is inline with Kahramaa strategic plans to comply with Qatar National Vision 2030.
