Optimization Configuration Method of Distributed Power Supply Considering Vulnerability Index

doi:10.3969/j.issn.1000－7229.2020.03.007

Abstract

Abstract: More distributed power supplies are connected to the grid. This trend has made distributed power sources more and more influential to the operational vulnerability of the grid. To solve this problem， firstly， the operational vulnerability of the power grid is studied， and then a comprehensive vulnerability index that can comprehensively evaluate the operation vulnerability of the power grid is proposed. Combined with the commonly used economic power consumption loss index and the static voltage stability index considering voltage quality， a multi-objective optimization configuration model considering the grid operation vulnerability index is established. The improved quantum particle swarm optimization algorithm is used to solve the model. The simulation example finally achieves the optimal configuration of the distributed power supply in terms of capacity and position. The results show that comparing with the traditional optimized configuration model， not only the grid economy and voltage quality can be guaranteed， but the grid operation vulnerability will be improved as well， thus the superiority of the proposed model being verified.

Key words: active distribution network, overall vulnerability of power grid, distributed power supply, improved particle swarm optimization algorithm, multi-objective optimization configuration
