Optimized Scheduling and Capacity Evaluation for Li-Ion Batteries in a PV-Enriched Modern Distribution Grid from a Techno-Economic Performance and Reliability Enhancement Perspective

Renewable energy generation (REG) gradually contributes more to modern power distribution systems to fulfill the increasing load demand. Modern distribution grids can improve power distribution performance and distribution grid reliability by integrating energy storage devices. This research suggests a methodology considering both AIC for Li-ion battery energy storage systems (BSSs) and the distribution grid dependability. In this paper, the proposed methodology aims to maximize the reliability of the distribution grid with techno-economic performance improvement by minimizing the AENS, DD, and AIC on BSSs through optimal capacity and CDS operation of BSSs through the PSO technique. The projected work has been performed in the solar-integrated 28-bus Indian distribution grid with yearly analysis. Reliability and demand profile improvement can be observed through the reduction in SAENS and SADD, which express that 16% reliability enhancement and 12% improvement in technical performance have been achieved with a minimum AIC of INR 30.22 lakhs in the considered power delivery grid.
