Impact of Electric Vehicle Charging Load on Power Supply Systems: Analysis and Optimization Strategies

Abstract

A wave of electric vehicle (EV) adoption is revolutionising contemporary transportation systems and in parallel, creating tremendous demands on the power supply infrastructure. Large-scale charging loads from electric vehicles (EVs) cause problems of voltage fluctuation, peak demand growth, and overloading of the transformer in distribution networks. This study analyzes the global effects of EV charging on power systems and how such impacts can be countered through optimizing strategies. The proposed methodology involves successively evaluating charging features, load behavior as well as grid infrastructure limits and at later stage provides the development of optimized charging model integrating demand-side management and intelligent scheduling. Results of Load balancing and Peak Demand Reduction is simulated and the analysis shows better grid stability. Researchers also emphasized the need for smart grid technologies and coordinated charging strategies to alleviate such impacts on power systems, as mentioned in their conclusions.
