Scheduling of Energy Storage System (ESS) for Electricity Distribution Companies (DISCOMs)

With the growth of distributed energy resources (DERs), there has been an overall increase in power generation. Because of this, the type of power produced fluctuates, contributing to grid instability. To lessen this unplanned power outage and avoid system disruptions, the electricity distribution companies (DISCOMs) give their schedules for 96-time blocks daily. The present study investigates the amount of Deviation Charges (DC) administered by DISCOMs in 15-minute time blocks due to the Deviation Settlement Mechanism (DSM). After examining the power deviation curve, it was observed that implementing Energy Storage System (ESS) at the distribution side and then facilitating their energy scheduling is the best practice to minimize the overall financial impact of the DISCOMs. Therefore, a simulation-based tool was proposed that includes Battery Control Algorithm (BCA) and Battery Degradation Model (BDM) for Kolkata DISCOM using real-time deviation data of 29 days. The results indicate that the proposed simulation-based model of ESS increased the project’s financial viability and the battery’s expected lifetime.
