Regional Integrated Energy System Control Strategy Considering Orderly Charging and Discharging of Electric Vehicles

The integration of large-scale Electric Vehicles (EVs) into Regional Integrated Energy Systems (RIES) poses new challenges to the optimization of RIES dispatch. This paper proposes a RIES day-ahead scheduling strategy that considers the bidirectional interaction between ordered charging sources and EV charging. Firstly, the unordered charging of electric vehicles is simulated, and on this basis, the orderly charging of the load side is guided by the user. Then, based on the power market summary, the uncertain factors in the process are fully considered, such as the wind power output at the source and the price demand response at the load side, and the system optimization scheduling is carried out to achieve the lowest daily economic cost of the system. Finally, through the analysis of simulation examples, it can be concluded that the optimal scheduling strategy proposed in this paper can effectively reduce the difference of peak and valley load of the system, improve the satisfaction of users on power consumption, increase the economic benefits of the system, and realize the orderly charging of electric vehicles.
