Park integrated energy system economic configuration method for promoting renewable energy consumption

Abstract

The invention relates to a park integrated energy system capacity economic configuration method, which comprises the following steps: building a park integrated energy system equipment steady-state model according to the energy supply architecture of a park integrated energy system; analyzing renewable energy output and load characteristics of the park, and constructing an excitation type demand response program; establishing an objective function of a park integrated energy system capacity economic configuration model considering demand response to promote renewable energy consumption, wherein the objective function considers an economic benefit objective and an environmental benefit objective; setting constraint conditions of the park integrated energy system capacity economic configuration model considering demand response to promote renewable energy consumption; and solving the park integrated energy system capacity economic configuration model by using an optimizer, and outputtingan optimal planning result. According to the method, economic and environmental objectives are considered, the demand response is considered to promote renewable energy consumption to improve the economy and environmental protection objectives of system capacity configuration, and a theoretical reference is provided for park integrated energy system planning considering the demand response.

Description

technical field [0001] The invention belongs to the technical field of park comprehensive energy system planning, and in particular relates to a method for economically configuring the park comprehensive energy system to promote the consumption of renewable energy. Background technique [0002] Global warming and energy crisis are two major problems and challenges facing mankind at present. The integrated energy system is based on the theory of multi-energy complementarity and energy cascade utilization, and can vigorously develop renewable resources, effectively control energy consumption, and improve energy utilization efficiency. It is of great significance to deal with severe challenges such as surge in energy demand, environmental pollution, and climate change. The integrated energy system at the park level is the basis for comprehensive energy services. Taking the park construction as the starting point, it is necessary to build a new energy production and consumption ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a comprehensive energy system economic allocation method to promote the consumption of renewable energy, which is used to solve one of the technical problems in the above-mentioned prior art, such as: many existing planning methods ignore environmental factors, but environmental problems It has been paid more and more attention by the government departments. Therefore, it is very necessary to incorporate environmental indicators into the planning objectives; in addition, under the development of the electricity market, demand response has great application potential, but many existing planning methods fail to Fully consider the potential value of demand response to further improve the rationality, economy, environmental protection and other goals of the system planning scheme
