Optimization Strategy of the Two-Stage Distributed Operation for Multi-Park Integrated Energy System Interconnection
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 two-stage 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 non-cooperative game are fair and reasonable.
