Optimized scheduling simulation method and system for regional integrated energy system

Abstract

The invention discloses an optimal scheduling simulation method and system for a regional integrated energy system. The method comprises the following steps: acquiring parameters of the regional integrated energy system; taking the parameter upper limit and the parameter lower limit of the regional integrated energy system as inputs of a pre-constructed optimal sub-model and a pre-constructed worst sub-model respectively, and solving by adopting a two-stage decomposition method to obtain the optimal energy consumption efficiency and the worst energy consumption efficiency of the regional integrated energy system respectively; constructing an optimal value range based on the optimal energy consumption efficiency and the worst energy consumption efficiency, forming an optimal scheduling scheme by the operation parameters of the devices corresponding to the numerical values of the optimal value range, and performing scheduling by adopting the optimal scheduling scheme; wherein the optimization model is constructed by taking a target function constructed by taking maximum energy consumption efficiency as a target and a constraint condition set for the target function. According to the method, the optimal sub-model and the worst sub-module are solved by adopting the two-stage decomposition method, the uncertainty of the distributed power supply and the load is considered, and the obtained optimization scheme is more reasonable.

Description

technical field [0001] The invention relates to the field of simulation optimization, in particular to an optimization scheduling simulation method and system for a regional comprehensive energy system. Background technique [0002] In the face of worldwide energy and environmental constraints, many countries have put energy conservation and energy efficiency at the top of their strategic positions. The application of renewable energy, multi-energy interconnection, and energy marketization are effective ways to promote efficient and clean energy utilization. At present, the biggest highlight of the new electricity reform plan is the release of the "electricity sales market", which has laid a solid foundation for the establishment of the Energy Internet and the promotion of energy marketization. The diversity of loads and energy types makes energy interconnection an inevitable trend, and the integrated energy system (IES) is a typical form of energy interconnection. With the...
