With the development of demand response technology, demand-side resources with flexible regulation characteristics such as temperature-controlled loads and electric vehicles can be used as generalized energy storage to participate in the control of power fluctuations in island distribution networks. This paper is oriented to two types of generalized energy storage, air conditioners and electric vehicles, and proposes a collaborative control strategy for distribution network that considers the participation of generalized energy storage clusters. Firstly, the load aggregator is used as the control center to build a multi-dimensional generalized energy storage cluster control architecture. Secondly, the generalized energy storage control model for the air-conditioning cluster and the electric vehicle cluster is established separately, and the number of controlled times of each air-conditioning is considered in the air-conditioning group. In the electric vehicle group, a power distribution strategy based on the state of charge is proposed. Then, according to the power response characteristics of the air-conditioning cluster and the electric vehicle cluster, a low-pass filtering-based multiple generalized energy storage coordinated control strategy is given. Finally, the simulation results based on Matlab/Simulink verify the effectiveness of this control strategy.

Key words: power fluctuation suppression, generalized energy storage, air-conditioning load, electric vehicle, cooperative control strategy
