摘要：
The energy router (ER), as a key device of Energy Internet, can flexibly control the power flow distribution, increase the voltage level, and realize the functions such as regional interconnection, energy mutual aid, and fault isolation. Studying the application of ER to achieve the optimization of AC-DC interconnected distribution network operation is of great significance. In this paper, the coordinated operation of ER and multiple active and reactive power regulating devices is taken into consideration, and a dynamic scheduling model of active and reactive power coordination under the dual time scales of day-ahead and intraday is proposed. This model takes the overall system cost and voltage deviation as the objective function. Discrete equipment scheduling and intraday continuous equipment adjustment cooperate with each other to achieve coordinated dynamic optimization. An improved multi-objective particle swarm algorithm (MOPSO) is proposed to solve the model. The improved IEEE 33-node AC distribution network and 13-node DC distribution network system are used as simulation samples. The results show that ER access has a positive impact on reducing power distribution system losses, improving power quality, optimizing operating strategies, promoting renewable energy consumption, and reducing overall costs, and the effectiveness of the algorithm is verified. © 2023 Science Press.
