Distribution System Reliability, Voltage Profile, and Power Losses Affected by EVCS Deployment

Electric vehicles are anticipated to play a vital role in transportation in the future because of their dependability and lower CO2 and greenhouse gas emissions. However, the advancements in battery technology, combined with rising concerns about environmental pollution, have prompted the electrification of transportation. Electric vehicles (EVs), which take the place of internal combustion engine-driven vehicles, have a negative impact on power system operating parameters. The high charging load of fast EV charging stations degrades the power systems utilizing the parameters. Customer dissatisfaction will result from the degradation of the reliability of the distribution network’s critical operating parameters. The research aims to quantify and investigate the deployment effects on the voltage profile, reliability, and power losses of EVCS load of standard IEEE 33 bus Radial Distribution test system using the MATLAB programming interface.

I. Introduction

A major concern for protecting the environment is the reduction of emissions of greenhouse gases from conventional engine-type vehicles. Excessive use of such vehicles leads to human health problems and degrades the planet’s ecosystem. Many researchers and policymakers worldwide are pushing for alternative modes of transport, such as electric vehicles, to minimize greenhouse gas emissions. The EVCS load is essential for the widespread adoption of electric vehicles. The wrong location of the EVCS negatively impacts the operating parameters and efficiency of the radial power distribution system. Therefore, researchers concentrated on enhancing system reliability to improve system efficiency and voltage stability. These goals can be achieved by investigating the optimal position and size of his EVCS within the distribution system [1]. Optimum and practical strategies describe the location and size of the energy storage equipment in a radial distribution grid. The proposed method aims to maximize grid reliability while maintaining safe grid operations.
