基于多主体收益的电-气综合能源系统协调规划研究

Coordinated Planning of Electricity-Gas Integrated Energy System Considering Multi-agent Profit

随着我国各种异质能源系统的发展建设以及对综合能源系统规划研究的深入,根据不同能源间多能互补的优势和特点研究最合理的综合能源系统规划方案,对于我国综合能源系统规划建设及可持续发展具有重要意义。提出了一种市场环境下计及多主体收益的电-气综合能源系统协调规划方法。首先,分别基于电力系统和天然气系统的特点及网络约束,构建相应的收益模型,进而结合电-气综合能源系统中的异质能源间的耦合机理分析,充分考虑各能源主体间的博弈关系,构建计及多主体收益的电力系统和天然气系统协调规划模型;然后,利用迭代搜索法求解该模型;最后,利用仿真算例对所提方法的正确性和有效性进行验证。

With the development and construction of various heterogeneous energy systems in China and the in-depth study of integrated energy system planning,it is of great significance for China’s integrated energy system planning and construction and sustainable development to study the most reasonable planning scheme according to the advantages and characteristics of multi-energy complementary between different energy sources.The paper proposes a coordinated planning method of electricity-gas integrated energy system with the consideration of the multi-agent profit under the market environment.First of all,based on the characteristics and network constraints of power system and natural gas system,the corresponding profit model is established.Based on the analysis of the coupling mechanism of heterogeneous energy sources in the electricity-gas integrated energy system and the game relationship among the energy entities,the coordinated planning model of the power system and natural gas system considering the multi-agent profit is constructed,Then,iterative search method is used to solve the model.Finally,the correctness and validity of the proposed method is verified by a simulation example.
