Abstract

With the development of wind and solar power, the randomness and uncertainty of the power system have brought challenges to the optimal dispatching of active distribution networks. A dispatching model based on the comprehensive carrying capacity index system is proposed to improve the safety and stability of the active distribution network under uncertain factors and to excavate the potential of controllable resources. Firstly, the comprehensive carrying capacity indicator system is proposed from the three sides respectively, including network and load. Then economic optimal dispatching model is established on the basis of the indicator system. Finally, the model and its effectiveness are verified by the simulation analysis of the improved IEEE 33 nodes system by Particle Swarm Optimization.
