Optimal Scheduling Of IES Under The Flexible Operation Mode Of Carbon Capture With Consideration Of Price Respons

With the"double carbon"target,reducing CO₂emissions has become a common goal in both traditional and new energy sources.Energy generation from new sources such as wind,hydrogen and biomass is safe and clean and plays an important role in the development of low-carbon electricity.However,due to differences in energy characteristics,it is important to choose energy rationally because of differences in the operation of the integrated energy thermal ITU supply system.Carbon capture and storage（CCS）technology can absorb the high CO₂ emissions from traditional coal-fired power plants and effectively transition from high to low carbon production.In addition,considering load side demand response can improve energy dissipation and reduce system operating cost,thus realizing the goal of economic operation of power system.Therefore,in order to promote the low-carbon and economic development of the Integrated Energy System（IES）,this paper,on the basis of conventional Combined Heat and Power（CHP）IES,considers energy diversity,introduces a price-for-electricity response to the low-carbon economic deployment of IES under different energy types,taking into account the joint operating model of carbon capture technology and wind power:Firstly,the basic structure and operating principle of IES are constructed and analyzed.On this basis,the operating characteristics of the energy supply unit model of biomass,hydrogen and CHP systems are analyzed in detail.The paper classifies the carbon capture technology,analyzes their operation characteristics,and establishes a mathematical model under the flexible operation mode of wind-carbon capture combined with wind power to lay a theoretical foundation for the research on the low-carbon scheduling of future IES.Secondly,aiming at the lowest operating cost of the system,the optimal scheduling model of CHP IES in wind-carbon capture flexible operation mode is constructed,and the CPLEX solver is called by MATLAB software to solve the example.Numerical results show that the efficiency and low carbon performance of IES are improved effectively under the operation mode proposed in this paper.Considering the influence of energy itself,carbon trading price and capacity of carbon capture equipment on the operational results of IES,different operating environments are set up,and the analysis of the applicable scenarios of different energy systems and the variation of operating results under different carbon prices and equipment capacity can provide important theoretical reference for the relevant IES to choose reasonable energy sources in the planning of low-carbon economy.Finally,by analyzing the demand response mechanism,this paper introduces the price response,takes into account the operating economy and low carbon of the system,and establishes the IES optimal scheduling model which combines wind energy and carbon capture to consider the price response.The results of two kinds of energy sources,IES power and thermal power,can be used to provide a reliable basis for the planning of IES low carbon economy.
