An integrated approach for scheduling electric vehicles and distributed generators in a smart distribution system

An increase in the utilisation of electric vehicles (EVs) and their irregular patterns usage creates a greater impact on electric distribution system performance. In this paper, an effective method of scheduling EVs, optimal location, and sizing of Distributed Generators (DG) is implemented. A novel smart charging method is proposed and implemented for scheduling the EVs in both grid to vehicle (G2V) and vehicle to grid (V2G) modes in this work. Also, a combined approach of voltage stability index (VSI) and grasshopper optimisation (GOA) method is implemented on the IEEE 33 bus system in the presence of EVs. The results are carried for three different cases with and without considering EVs in both V2G and G2V modes. The proposed smart charging method provides a better solution in managing the system peak demand thereby reducing the power loss of the overall network and improving the voltage profile.
