Abstract

The invention discloses a robust optimization scheduling method and device for a comprehensive energy system, and the method comprises the steps: carrying out the clustering of a wind power predictionerror sample set through an infinite-dimension Gaussian mixture model, and obtaining a data-driven wind power prediction error uncertainty set; establishing a robust optimization scheduling model ofthe electrical comprehensive energy system according to the wind power prediction error uncertainty set, wherein the robust optimization scheduling model comprises a day-ahead plan scheduling stage and a real-time operation scheduling stage; solving a day-ahead plan scheduling stage to obtain a decision-making unit start-stop and output interval and a natural gas supply amount interval; solving the real-time operation scheduling to obtain the output value of the decision-making unit and the gas supply amount of the natural gas. According to the invention, the problem of IEGS coordination optimization in an uncertain environment of wind power output is solved.

Description

technical field [0001] The present application relates to the technical field of electric power dispatching, in particular to a method and device for robust optimal dispatching of an integrated energy system. Background technique [0002] In recent years, with the introduction of concepts such as "Energy Internet", the integration and transformation of various energy forms has become a research hotspot at home and abroad. Integrated electricity and gas system (IEGS) refers to a modern energy system that takes electricity as the core and integrates natural gas systems. Compared with other primary energy sources, natural gas is clean and environmentally friendly, so it is of practical significance to study the interaction between it and the power system. In recent years, scholars at home and abroad have done some basic research on the optimal operation of IEGS. The current research mainly focuses on the IEGS planning method considering various energy storage such as electric...
