Scheduling method of electrical integrated energy system based on information gap decision theory

Abstract

The invention discloses an electrical comprehensive energy system dispatching method based on the information gap decision theory, which includes: establishing a theoretical model for information gap decision-making; establishing an optimal economic benefit operation model after combining wind power-pumped storage units; considering wind power output uncertainty Establish a wind-storage combined unit scheduling model based on the information gap decision theory; establish a deterministic electrical integrated energy system scheduling model; consider load uncertainty and establish an electrical integrated energy system scheduling model based on the information gap decision theory; combine the bacterial population The chemotaxis algorithm solves the model; the solution result is sent to the energy dispatching center, and the energy dispatching center dispatches the energy system according to the solution result. The scheduling strategy proposed by the invention can effectively reduce the intermittency and volatility of wind power, increase the consumption of wind power and increase the economic benefits of the electrical comprehensive energy system, and provide different scheduling strategies for decision makers with different risk preferences.

Description

technical field [0001] The invention relates to the energy field, in particular to an electrical comprehensive energy system scheduling method based on information gap decision theory. Background technique [0002] Since traditional fossil fuels are non-renewable, improving the utilization rate of renewable energy has become a key issue, and the key to increasing the high proportion of renewable energy penetration in the power system is to increase the operational flexibility of energy consumption measurement, thus proposing the concept of "integrated energy system" a concept. In the comprehensive energy system, the electric-gas comprehensive energy system is the top priority, and the electric power system and the natural gas system are two energy systems that operate independently of each other. However, due to the fast start-stop and fast load adjustment characteristics of gas turbines, the consumption of natural gas has increased rapidly worldwide. It is estimated that ...
