在“双碳”背景下，为推进园区级综合能源系统(integrated energy systems, IES)建设、提升清洁能源消纳能力、降低园区碳排放，以综合能源系统运行总成本最小为目标函数，系统安全和机组出力为约束条件，引入电转气与碳捕获系统耦合设备，综合考虑了阶梯式碳交易和碳封存成本，建立了含氢储能的综合能源系统低碳调度模型。最后以某园区为算例，运用CPLEX求解器对所提模型进行求解，算例结果表明所建模型能够有效提高系统的经济性与低碳性，提高园区新能源消纳能力，减少弃风弃光等成本，进一步降低园区碳排放并减少经济运行成本，提高综合能源系统运行灵活性。
英文摘要:
Under the background of "double carbon", in order to promote the construction of integrated energy system (IES) at the park level, enhance the clean energy consumption capacity and reduce carbon emission, the utilization and sequestration of carbon dioxide generated by the operation of IES are considered to reduce carbon emissions. In this paper, with the minimum total operating cost of IES as the objective function, taking the unit output and system safety as the constraints, introducing the coupling device of power-to-gas and carbon capture system, we establish a low-carbon dispatching model of IES with hydrogen storage at the park level considering stepped carbon trading and carbon storage cost. Taking a park as an example, the CPLEX solver is used to solve the model. The example results show that the proposed model can effectively improve the economy and low-carbon nature of the system, improve the new energy consumption capacity in park, and reduce the cost of wind and light abandonment, which can effectively reduce the carbon emissions and operating costs of the park and improve the flexibility of IES operation.
