Selecting Energy Storage Systems with Wind Power in Distribution Network

In distribution systems, load demand can exceed the feeder thermal limit during peak demand periods and cause system damage. This situation can be prevented by load shedding, which results in financial losses to utilities and customers. The problem can be countered by utilizing energy storage systems (ESS) properly. In this paper, we formulate an optimization problem combining the utilization of ESS and wind power in a typical distribution system, whereby real power is optimally scheduled in an electricity market under the constraint that the load demand cannot exceed feeder thermal limit. This approach ensures the reliable operation of the power distribution system and prevents outages. The developed optimization problem is solved for a typical distribution system. The results clearly demonstrate the economical operation of ESS with wind power in distribution systems to prevent outages and maximize the ESS profit.
