An innovative technique for energy storage system management based on vanadium redox batteries

In this paper, a management strategy to be used in the scheduling of insular electrical systems with energy storage system (EES) is presented. Integration of ESS allows reducing generation costs and greenhouse gases (GHG) emissions, as well as improving wind power penetration levels. The methodology presented in this paper is particularly useful for those systems provided with battery ESS, due to it is ability to include the effects of the most relevant components, such as thermal and renewable generation, bidirectional power converter, and charge controller operation. From the analysis of a case study considering a diesel-powered system and a Vanadium Redox Flow Battery (VRFB), it is possible to estimate the potential reduction on fuel consumption and wind power curtailment, in comparison with a case without EES.
