摘要
In order to further tap the cooperation potential of each stakeholder and improve the balance of energy supply and demand in the multi-microgrid distribution system, a collaborative energy management optimization strategy based on generalized Nash bargaining is proposed. The negotiation process is divided into two stages according to the interest interaction among the distribution network layer, microgrid layer and user layer. In the first stage, the distribution network negotiates with multiple microgrid-user sub-alliances to realize coordinative optimal operation and surplus sharing of each stakeholder. In the second stage, the benefit settlement is performed within each sub-alliance. Considering the benefit of each stakeholder, a corresponding two-stage bargaining model is built, and the benefits of all participants are asymmetrically distributed by introducing the bargaining power. The first stage bargaining model is decomposed into two sub-problems of maximization system benefit problem and benefit distribution, and the two-block alternating direction method of multipliers is adopted to realize distributed solution. The example results show that the proposed strategy can effectively realize reasonable benefit distribution, improve the economic benefit of each stakeholder, and is helpful for improving the voltage quality of distribution network and renewable energy consumption level. ? 2024 Electric Power Automation Equipment Press.
