Abstract

The invention discloses a comprehensive energy system optimization method and system considering the demand side response uncertainty, and the method comprises the steps: establishing the regional comprehensive energy system energy coupling matrix considering the demand side response, proposing the comprehensive demand response linear model, exploring the relationship between the excitation priceand the demand response range, describing the uncertainty of demand response by adopting an interval method, obtaining an interval in which a user participates in the demand response by only needing asmall amount of data, establishing an optimization model taking the lowest operation cost as a target and taking network constraint, equipment constraint, demand side response constraint and power balance constraint as constraints, and providing a solution scheme. According to the method, the energy utilization efficiency of the system can be effectively improved, the operation cost of the regional comprehensive energy system is reduced, the benefit maximization of supply and demand sides is realized, and help is expected to be provided for research of regional comprehensive energy demand response.

Description

technical field [0001] The invention relates to the technical field of demand-side response of an integrated energy system, in particular to an optimization method and system for an integrated energy system considering the uncertainty of the demand-side response. Background technique [0002] At present, the global energy crisis and environmental problems are becoming more and more serious, renewable energy has been vigorously developed, and the regional integrated energy system has become a key link in the transformation and development of the energy structure.
