Enhancement of the distribution network in the presence of EV charging stations augmented by distributed generation

With the exponential growth of electric vehicles worldwide, integrating fast electric vehicle charging stations into the distribution system has become crucial. However, this integration can lead to adverse effects such as high power loss and poor voltage profiles. To address these challenges, this research focuses on two strategies: optimal placement of charging stations and allocation of distributed generation within the distribution system. The study investigates the negative impact of charging stations and the positive effects of distributed generation on an IEEE-25 unbalanced radial distribution system. The objective is to reduce active power loss, enhance voltage profile and improve the voltage stability index. The research employs a transient search optimization algorithm to optimize a multi-objective function. MATLAB simulations validate the proposed algorithm, showcasing its convergence characteristics across various scenarios. By exploring the effects of charging stations and distributed generation, this research contributes insights into mitigating negative impacts and utilizing distributed generation for enhanced distribution system performance.
