Operation Optimization of Electrothermic Hydrogen Co-supply Micro-grid Considering Demand Response and Stepped Carbon Trading
摘要
Abstract
In order to achieve the low-carbon economic operation of micro-grids,an optimization model for the operation of an electrothermic hydrogen co-supply micro-grid is established,which comprehensively considers stepped carbon trading and demand response.The model introduces a step carbon trading mechanism to reduce carbon emissions.Additionally,an electricity price-based demand response is incorporated to guide users in altering their behavior of using electricity,thereby reducing the economic cost of micro-grid.The objective function is set to minimize the sum of the operation and maintenance costs,energy purchase costs,and carbon transaction costs.The operation optimization model includes components such as wind power,photovoltaic,gas turbines,electric boilers,electrolyzers,fuel cells and hydrogen storage tanks within a grid-connected micro-grid system.The model is solved using the CPLEX solver on the Matlab platform.Taking an improved grid-connected micro-grid with electric and hydrogen supply as an example,several scenarios are set to verify the rationality and validity of the model.The results show that in the scenario of demand response and stepped carbon trading,carbon emissions are reduced by 65.6%,and the total operating cost is reduced by 10.7%.关键词
