摘要：

With the wide application of distributed energy resources and electric vehicles in the distribution network, the power imbalance in the distribution area (DA) and the problem of light and heavy load operation have become increasingly severe, threatening the safe and stable operation of the distribution network. Thus, a soft open point (SOP) regulation strategy considering transformer economic operation area applied to the interconnection of DAs is proposed to achieve load balance between DNs. Further, aiming at the voltage fluctuation of DC bus caused by the load regulation, a fast energy balance control based on the regulation strategy is proposed. It can effectively improve the voltage recovery speed and the fluctuation suppression ability of the DC bus and ensure the effective implementation of the regulation strategy. Finally, the simulation and experimental results show that the proposed regulation strategy can effectively solve DAs' power imbalance and heavy load problems. Moreover, the fast energy balance control has excellent power response and fluctuation suppression ability. The proposed method has strong engineering practicability and popularization value. © 2023 Power System Technology Press. All rights reserved.
