A Novel Newton Raphson-Based Method for Integrating Electric Vehicle Charging Stations to Distribution Network

Electric vehicle sales are rising due to numerous factors such as government policies, falling prices, advanced, and eco-friendly technology. Built-in battery packs are charged using the energy from the distribution network. When a large number of electric vehicles are simultaneously charged with high power, the distribution network can be adversely affected. Differences in electricity supply and demand on the distribution network, voltage imbalance, and power losses are among the examples of effects. In this study, a mathematical model has been proposed in order to properly handle the effects of charging stations on the distribution network. According to the model, the optimum placement of electric vehicle charging stations is achieved within the constraints of the distribution network. In order to prove the robustness and validity of this model, the proposed model is applied to IEEE 33-bus radial test system. Results are discussed in cases.
