Optimal Scheduling and Operating of Active Distribution Network Considering Comprehensive Carrying Capacity

doi:10.3969/j.issn.1000-7229.2020.02.008

Abstract

Abstract: With the increasing penetration of wind and solar power， the uncertainties bring great challenges to the optimal scheduling of active distribution network. In order to improve the ability of active distribution network to deal with uncertain disturbances， an optimal scheduling method is proposed to enhance the comprehensive carrying capacity of active distribution network. Firstly， comprehensive carrying capacity is proposed from the aspects of resource adequacy and operation safety of active distribution network. Then， based on the coordinated scheduling of various active management resources， an optimal scheduling model of active distribution network considering comprehensive carrying capacity is constructed. Secondly， the graph theory “broken circle” method is introduced to improve the encoding strategy of the grid， and the hybrid encoding particle swarm optimization algorithm is used to solve the model. Finally， an improved IEEE 33-node system is taken as an example to verify the validity of the model.

Key words: active distribution network, comprehensive carrying capacity, active management
