针对多个园区综合能源系统间存在能源浪费及利益冲突的问题,首先提出了考虑多主体博弈的园区综合能源系统双层优化模型,其中上层模型利用多个园区间经济关系进行合作博弈,得到园区间交互能量功率并将所得功率传输给下层模型,下层建立多目标合作博弈模型进行设备调度并反馈能源需求。其次,上下层合作博弈皆采用交替方向乘子法进行解耦,并交替迭代得到最优策略方案。最终利用Shapley值法进行利益分配。结果表明,园区多主体间的合作可以有效提升园区综合能源系统经济效益。实现多能源灵活调度及能源系统经济效率提升。
Abstract:To address the problems of energy waste and conflicting interests among multiple park integrated energy systems(PIESs),a two-layer optimization model for a PIES considering multi-agent game is proposed in this paper. In this model,the upper-layer model uses the economic relationship among multiple parks to perform cooperative game,thus obtaining the interactive energy power among parks and further transmitting the resulting power to the lower-layer model. In the lower-layer,a multi-objective cooperative game model is established to dispatch the equipment and feedback the energy demand. Then,the cooperative game in both the upper and lower layers is decoupled using the alternating direction multiplier method,and a scheme of optimal strategy can be obtained through alternating iterations. Finally,the benefits are distributed using the Shapley value method. Results show that the cooperation among multiple agents within one park can effectively improve the economic benefits of PIES and achieve flexible dispatching of multiple energies as well as an increase in the energy system's economic efficiency.
