基于合作博弈的多综合能源服务商运行优化策略

Operation Optimization Strategy of Multi Integrated Energy Service Companies Based on Cooperative Game Theory

随着能源市场化的发展,综合能源服务商(integrated energy services company,IESC)将取代原有的能源网络对用户提供能源服务。在区域综合能源系统中,可能存在多个综合能源服务商,其既可直接与上级能源系统进行能源交易,又可以与同区域中的其他服务商进行交易。利用能源枢纽对综合能源服务商建模,考虑多综合能源服务商参与日前能源交易,提出一种基于纳什议价模型的合作博弈运行策略,进而将纳什议价模型转化为2个可求解的线性子问题并利用分布式算法顺序求解。最后,通过算例仿真验证了所提模型和方法能够实现多综合能源服务商之间的合作博弈,有效降低综合能源服务商总成本。

With the development of energy marketization,integrated energy services company(IESC)will replace the original energy network to provide energy services to users.In the regional integrated energy system,there may be multiple integrated energy service companies,which can not only directly trade with the superior energy system,but also trade with other service companies in the same region.In this paper,the energy hub was used to model the integrated energy service company.Considering the participation of multiple integrated energy service companies in day ahead energy trading,a cooperative game operation strategy based on Nash bargaining model was proposed.Then,the Nash bargaining model was transformed into two linear subproblems that can be solved in sequence by using distributed algorithm.Finally,the simulation results show that the proposed model and method can realize the cooperative game among multiple integrated energy service companies and effectively reduce the total cost of integrated energy service companies.
