The increasing number of distributed new energy and electric vehicle (EV) charging and discharging stations provide convenience for humanity, but also impose tremendous pressure on the distribution network (DN), resulting in a synchronous decrease in the power quality and economic benefits of DN. However, traditional methods such as adjusting reactive power compensation devices and transformer tap changers cannot keep up with the pace of the intelligentization of DN, and are difficult to adapt to the characteristics of recent DN with multiple changes and faults. Therefore, it will greatly alleviate the pressure brought by the high-penetration of new energy connected to DN when the reactive power regulation (RPR) potential of new energy can be reasonably developed. In this paper, RPR models for wind power, photovoltaic, EV charging and discharging piles are constructed. Optimization objectives include line loss and voltage deviation. Simulations have analyzed cases with different environmental parameters and various DN topologies, and five algorithms are applied to solve the above models. The simulations present that the models proposed above can obtain better solution sets that approximate the actual Pareto front.
