考虑新能源消纳与低碳排放的多电-气互联系统合作博弈

COOPERATIVE GAME OF MULTI-POWER-GAS INTERCONNECTION SYSTEM CONSIDERING NEW ENERGY CONSUMPTION AND LOW CARBON EMISSION

双碳目标下为提高新能源消纳量和降低碳排放量,建立考虑灵活资源和碳捕集的多电-气互联系统低碳合作博弈模型。该模型以实现大量灵活设备参与调度情况下,将低碳运行效益最大化,同时提高系统能源综合利用率;并采用非对称纳什议价方式在多区域间博弈合理分配各系统利益,以提高各子系统主动参与合作机制的积极性。考虑到所建模型为凸优化问题,采用分布式ADMM算法求解,具有良好的收敛性和鲁棒性。算例分析表明,合作博弈机制能实现不同区域和不同类型灵活设备的电能协调优化调度,提高系统风电、光伏等新能源发电的接纳能力,同时可有效降低区域综合能源系统的净成本和碳排放量。

In order to increase the consumption of new energy and reduce carbon emission under the“double carbon”target,a multi-regional low-carbon cooperative game model considering flexible resources and carbon capture is proposed.This model can maximize the benefit of low-carbon operation when a large number of flexible equipment participate in scheduling,meanwhile improve the comprehensive energy utilization rate of the system.And the use of asymmetric Nash bargaining in multi-regional game rational allocation of the interests of the system,improve the enthusiasm of each subsystem to actively participate in the cooperation mechanism.Considering that the proposed model is a convex optimization problem,the distributed ADMM algorithm is used to solve the problem,which has good convergence and robustness.Through the comparative analysis of examples,it is proved that the cooperative game mechanism can realize the coordinated optimal scheduling of electric energy in different regions and different types of flexible equipment,which can increase the acceptance capacity of new energy power generation such as wind power and photovoltaic power,at the same time effectively reduce the net cost and carbon emissions of regional integrated energy system.
