Can a battery energy storage system shave peak load hours?
This is in addition to the peak load hours witnessed by the system. A potential solution to the problem is using battery energy storage system (BESS) to shave the load peaks the load peaks and store the surplus electricity from RES when needed. This project studies a system with and without the local generation by wind and solar power plants.
What is peak load?
Peak load is a sensitive factor in distribution network, which happens periodically only for a small percentage of time per day. To provide peak load, a conventional approach involving capacity increase (small gas power plants and diesel generators) is traditionally used.
How to provide peak load?
To provide peak load, a conventional approach involving capacity increase (small gas power plants and diesel generators) is traditionally used. However, this approach is not economically feasible and inefficient in the use of generators because it is used to maintain production capacity for only a few hours a day .
