摘　　要：针对多个园区互联形成的多园区综合能源系统园区间电能交互、收益分配问题,首先,构建园区间电能交互运行框架;其次,从电力市场、隐私保护角度出发,提出一种两阶段分布式运行优化策略,第一阶段求解园区间的电能交互量,第二阶段基于非合作博弈理论出清园区互联运行模式下的电能交互成本与收益;最后,采用交替方向乘子法分离耦合变量依次对两阶段模型分布式求解。结果表明,交替方向乘子法在保护各主体隐私的前提下实现了两阶段模型的高效迭代求解,园区间通过电能交互整合资源降低了运行成本,经非合作博弈出清后的园区收益公平合理。For the multi-park integrated energy system formed by the interconnection of multiple parks,the power interaction and revenue distribution among parks are discussed in this paper.Firstly,the interactive operation framework of electric energy between parks is constructed.Secondly,from the perspective of electricity market and privacy protection,a twostage distributed operation optimization strategy is proposed.In the first stage,the amount of electric energy interaction between parks is solved,and in the second stage,the cost and income of electric energy interaction under the interconnection operation mode of parks are clarified based on the non-cooperative game theory.Finally,the two-stage model is solved sequentially and distributed using the alternating direction multiplier method.The results show that the alternating direction multiplier method can better realize the iterative solution of the two-stage model,the operation cost of the parks is reduced through the integration of energy resources,and the profits of the parks after the noncooperative game are fair and reasonable.
