Research on an Orderly Charging Strategy for New Energy Charging Stations Based on Dynamic Electricity Prices and a Reservation Charging Mechanism for Electric Vehicles

With the advancement of the economy, the issue of energy supply and pollution has grown increasingly critical. Electric Vehicles (EVs) and innovative energy sources are progressively gaining popularity as a means of reducing the environmental damage caused by societal development. Photovoltaic charging stations can help integrate renewable energy and electric automobiles, and they have a promising future. This paper proposes a reservation charging model based on EV owners' willingness from the perspective of aggregator profitability and reducing the load peak-to-valley difference, as well as pre-consumption of PV for real-time charging EVs without advance reservation, which reduces the negative impact of direct PV access to the distribution network. The model is independent of PV power generation and EV charging data predictions, and it provides a theoretical foundation for how PV charging stations can achieve orderly charging management for EVs according to the peak-valley tariff and grid load characteristics. It can effectively reduce the load peak-valley difference and improve aggregators' net profit through the analysis of calculation cases.
