摘要
随着全国碳排放权交易市场的开放,研究碳交易对于多区域综合能源系统的低碳经济运行具有重要意义。首先,针对目前碳交易成本计算既没有计及碳排权购买量约束,也没有考虑区域综合能源系统之间碳排权供求互动的问题,提出一种考虑碳排权供求关系的碳交易成本联合计算方法;然后,计及区域综合能源系统之间的功率交互,建立了基于纳什谈判的多区域综合能源系统合作博弈模型;接着,将合作博弈问题分解成两个子问题分步求解,并采用控制变量法分析了碳交易成本联合计算与区域综合能源系统之间功率交互对系统的影响;最后,通过三区域综合能源系统仿真算例进行多场景对比分析,结果表明所提模型在显著降低经济成本的同时能够避免碳排放超标。
With the opening of the national carbon emission trading market,carbon trading cost has become an important factor affecting low-carbon economic operation of the multi-regional integrated energy system(MRIES).The existing carbon trading cost calculation is based on the premise that the supply of carbon emission rights exceeds the demand.However,the supply of carbon emission rights in the carbon emission trading market may not meet the purchase demand of carbon emission rights in a regional integrated energy system(RIES),resulting in the shortage of carbon emission rights.Therefore,there should be a numerical upper limit on the amount of carbon emission rights purchased by the RIES in the process of carbon emission trading,which in turn is affected by the amount of carbon emission rights sold by other RIESs in the MRIES.In view of the above situation,a joint calculation model of carbon trading cost considering the relationship between supply and demand of carbon emission rights and the constraint of the amount of carbon emission rights purchased was proposed,which can study the carbon emission trading within the MRIES and the carbon emission trading between the MRIES and the external system.The model also has nonlinear constraints,and it needs to be linearized by introducing new decision variables to reduce the computational difficulty.In addition,in order to make use of the characteristic of multi-region interconnection of MRIES,a cooperative game model of the MRIES based on Nash bargaining considering the electric power and thermal power interaction between different RIESs was proposed,which can strengthen the connection between different RIESs,reduce the overall economic cost of MRIES and realize the function that the price of power interaction can be set flexibly among different RIESs.But the cooperative game model is a nonconvex nonlinear model,which needs to be transformed into two subproblems to be solved step by step.The lowest economic cost of the MRIES was calculated in the first subproblem to improve th
