Abstract

The invention discloses a regional comprehensive energy system operation optimization method considering comprehensive demand response. The method comprises the following steps: S1, establishing renewable energy, energy conversion equipment and energy storage equipment models; S2, establishing a comprehensive demand response model based on three loads of electricity, heat and gas; S3, establishinga regional comprehensive energy system operation model considering comprehensive demand response; and S4, substituting the electricity, heat and gas load prediction results in the future 24 hours into the model in the step S3, and solving in a Cplex optimizer. According to the characteristics of energy supply and demand response of the regional comprehensive energy system, energy is converted mutually, the phenomena of wind curtailment and light curtailment are reduced, energy storage and supply are increased, and the regional comprehensive energy system operates stably and economically.

Description

technical field [0001] The invention belongs to the field of energy optimization operation, and in particular relates to an operation optimization method of a regional comprehensive energy system considering comprehensive demand response. Background technique [0002] As an important component of the development of the Energy Internet, the regional integrated energy system is of great significance to the development, consumption and improvement of social energy utilization efficiency of renewable energy, as well as national energy conservation and emission reduction. In order to reduce the inherent intermittency and volatility of renewable energy in the energy system, methods such as deep peak shaving technology, energy storage technology, and demand-side response have been proposed. Among them, Integrated Demand Response (Integrated Demand Response, IDR) means Or the incentive mechanism stimulates demand to adjust energy production and consumption patterns to achieve the co...
