Recent advances in energy storage technologies and their increased deployment in power systems have improved the network flexibility and brought a number of economic benefits. Apart from typical energy storage applications during the network nominal operation, energy storage can significantly improve the quality of service under fault conditions and increase principal reliability indices. However, economic aspects of energy storage operating under these conditions have been seldom studied. This

A novel methodology is proposed that calculates both technical and economic reliability indices for a distribution network and then uses them to determine the benefits of energy storage integration. Technical parameters and investment cost of different energy storage technologies are considered. Finally, a benefit-cost ratio index is defined to analyse and quantify the investment proportion that can be recovered by this specific reliability improvement.
