Stability coordination control of multi-resource integrated microgrid considering demand response

Abstract

Fully exploit the demand-side resources to build a multi-energy complementary microgrid system, which can improve the stability control of multiple indicators and save system operating costs. Based on the microgrid architecture including gas turbine generator set, energy storage system and central air-condition, each part of the system model is constructed to study the complementarity between resources, and a multi-resource integration multi-user regulation configuration method is proposed. Based on the principle of reverse thrust control, the multi-objective stability coordination control strategy of the microgrid system in off-grid mode is proposed, and the stability of the controller is proved theoretically. The control algorithm is verified by a simulation example. The result shows that the coordinated controller can ensure the tracking and adjustment of multiple controlled quantities such as power angle and frequency of the microgrid system during control, and the system can be quickly pulled back to stable operating state after the control is over. The participation of demand response resources in micro-network regulation can effectively improve the dynamic response of each state quantity of the system, and improve system stability, and reduce system control expenditure.
