Comprehensive energy system operation optimization device considering user demand response characteristics under carbon emission cost

Abstract

According to the comprehensive energy system operation optimization device considering the user demand response characteristics under the carbon emission cost, based on a computer system, the carbon emission characteristics of a coal-fired power generation unit and a gas-fired boiler are analyzed, a comprehensive energy system carbon dioxide emission model and a stepped carbon emission cost model are constructed, and the user demand response characteristics of the coal-fired power generation unit and the gas-fired boiler are optimized. Calculating the carbon dioxide emission cost of energy consumption at each moment; on the basis, a user demand response model guided by double signals of the carbon emission cost and the energy purchase price is constructed, and an integrated energy system operation scheduling model is constructed with the purpose of minimizing the energy purchase cost and the carbon emission cost of the integrated energy system. The system can fully reflect the environment cost of operation of coal electricity, fuel gas and other equipment, more effectively encourages a user to use more energy in the clean energy output peak period, promotes the consumption of clean energy, reduces the wind and light abandoning conditions of the system, and reduces the degree of dependence on external energy at the same time.

Description

technical field [0001] The invention belongs to the technical field of comprehensive energy system optimization operation, and in particular relates to a comprehensive energy system operation optimization device that considers user demand response characteristics under carbon emission costs. Background technique [0002] Energy is a necessity for today's economic and social development. Due to the problems of non-renewable fossil energy and environmental pollution, improving the utilization efficiency of clean energy under the premise of safe energy supply has become the focus of the current energy field.
