A load flow analysis for distribution system under various mathematical load models of electric vehicle

This paper presents the load flow analysis for different mathematical models of electric vehicle (EV) load based on the recursive equation. For calculation of power loss (active and reactive loss), load voltage deviation (LVD) and voltage profile, the loads are considered as voltage-dependent loads. The IEEE 33 node radial distribution network is used to test the efficacy of algorithm. Compared to the CP case, the penetration level of EVs 26.88% is considered. Results show the impact of the EV load models on a distribution system. The EV2 load model has the highest impact while EV1 load model has the lowest impact on the distribution system losses and LVD. The results indicate that the mathematical modelling of EV2 has the highest impact on total active and reactive power losses, and LVD. Hence, the load modelling of EVs is an important factor to investigate the system performance and load flow analysis. © 2022 Inderscience Enterprises Ltd.
