Demand Side Management Strategies for the Introduction of Electric Vehicles: A Case Study

Electric vehicles (EVs) offer a promising solution for urban mobility, providing a clean alternative for energy consumption and contributing to the reduction of CO2 emissions, which aligns with global environmental objectives. The growth of electric vehicles brings with it new challenges and restrictions for users in terms of active contracted power. In the face of these challenges, demand-side management studies are necessary to avoid criticalities in the grid for the concessionaires as well as penalties for exceeding the contracted demand for users with composite tariffs. This study evaluates the impacts of EV integration on the contracted demand of a medium voltage consumer, based on power flow studies monitoring the voltage at the busbars and the total power in the system. In this way, different charging scenarios are considered, as well as management strategies to optimize EV charging considering recharging criteria and restrictions to meet the defined power and voltage requirements. The results validate the proposed methodology for its use in the analyzed consumer.
