Distributed Coordination and Optimization Model of Multi-stakeholder in Active Distribution Network

The increasing amount of distribution generations (DGs) integrated into active distribution networks (ADNs) brings new challenges to the safe and economic operation of active distribution networks. Meanwhile, the traditional centralized method in the operation leads to the heavy computation burden in large-scale distribution networks. In addition, with the continuous advancement of the electricity market, many types of stakeholders will coexist in distribution network, such as micro-grid and visual power plants. A fully distributed multi-stakeholder coordination and optimization model is proposed in this study, where the reactive power support of DGs is specially addressed. The distributed multi-stakeholder coordination and optimization framework is set up and solved by alternating direction method of multipliers (ADMM). Finally, numerical results based on a 3-stakeholder IEEE 33-bus system and a 6-stakeholder 152-bus system verify the effectiveness of the proposed method.
