Evaluation of the reliability of the deregulated radially distribution network with consideration of vehicle to grid

The necessity of reducing fossil fuels and environmental pollutants has led to consideration of Electric Vehicles (EVs). EVs can participate as a manufacturer in the electricity market through Vehicle to Grid (V2G) technology. This greatly improves the reliability of distribution systems. Therefore, it is necessary to plan the charging and discharging processes in the parking lot. This paper investigated different strategies for planning the charging and discharging processes of EVs considering the random and unpredictable nature of various parameters, as well as the limitation of the power exchange between the distribution system and parking, to evaluate the impact of V2G-equipped parking lots on reliability. An appropriate strategy is the strategy that increases the owner's interest in the parking. Therefore, the strategies are designed independent of the duration of EVs presence in the parking and considering the limitations of power exchange with the distribution system. In addition, the improvement of the reliability of the distribution system and the economic benefits of V2G are examined simultaneously. The results indicate that V2G and charge-discharge strategies increase the parking revenue by an average of 21.6% and improve reliability (System Average Interruption Frequency Index (SAIFI), System Average Interruption Duration Index (SAIDI), Average Service Availability Index (ASAI), and Energy Not Supplied (ENS) indices) of the distribution network by 8.8%.
