Document Type and Number:
WIPO Patent Application WO/2024/077667
Kind Code:
A1
Abstract:
A security zone construction method for an electro-thermal integrated energy system, relating to the fields of energy system modeling and operation analysis. The method specifically comprises: establishing an electro-thermal integrated energy system dynamic model, wherein the electro-thermal integrated energy system dynamic model comprises an electric power system model, a quality adjustment thermal system dynamic model, and a combined heat and power unit dynamic model; according to operation security constraints, establishing an electro-thermal integrated energy system security zone model related to heat dynamics; and for non-linear and non-convex characteristics of a security zone of the electro-thermal integrated energy system, solving the boundary of the security zone by using a convex hull method based on optimization and verification, and delineating the security zone. The operation characteristics of the electro-thermal integrated energy system are accurately delineated by comprehensively considering the heat dynamics of device and network sides in the electro-thermal integrated energy system. A limit operation point is solved by means of a convex hull method based on optimization and verification, so that the absolute security of the security zone obtained by solving is guaranteed, thereby providing theoretical guidance for operation analysis of the electro-thermal integrated energy system.
