Retired Electric Vehicle Battery untuk Security Constrained Dynamic Economic Dispatch dengan Mempertimbangkan Pembangkit Energi Baru Terbarukan

Abstract

In the era of rapidly developing electric vehicles, new issues arise regarding electric vehicle batteries reaching 80% of their initial capacity and becoming waste (REVB). However, these batteries can be reused as Battery Energy Storage System (BESS). The objective of this final project is to investigate the impact of REVB on SCDED with PV integration in reducing generation costs using General Algebraic Modeling System (GAMS) software and Linear Programming (LP) methods. Based on the the simulation results, it was found that the utilization of REVB contributes to reduction in thermal generation costs. In the IEEE 30 bus systems, there was a cost reduction of 10.79%. Meanwhile, in the 118 bus systems, there was a cost reduction of 11.05%. These reductions help optimize the use of thermal generations and reduce fuel cost. Additionally, the integration of REVB also plays a role in maintaining system security. In the IEEE 30 bus system, the integration of REVB allowed testing of transmission capacity reduction up to 45% from normal conditions, an increase from the previous limit of only 45%. In the IEEE 118 bus system, the limit for transmission capacity reduction also increased from 25% to 35%. In this context, REVB contributes to improving system security by expanding the limits for testing transmission capacity reduction.
