Research on cluster operation optimization of multi‐port energy routers

Abstract The penetration rate of distributed new energy and DC load increase in the distribution network improve the new energy consumption rate and the reliability of power supply. This paper proposes an AC/DC hybrid system structure with multi‐port energy router (ER) cluster, and compares the advantages of this structure over the AC/DC hybrid microgrid with multiple conversion links. In order to realize the stable, economic, and reliable operation of this structure, the multi‐layer and multi‐time scale control method and communication mode are established. According to the non‐linear characteristics of energy consumption of ER port, the optimization model of the cluster control layer and the control mode of each port in the cluster system are studied. By setting several examples, the rationality of the proposed ER cluster operation control mode and the optimization method and the effectiveness in improving the total energy efficiency of the ER cluster system are verified; the advantages of ER cluster operation in improving the operation energy efficiency of key devices in the distribution network are illustrated.
