Distributed Power Service Restoration Method of Distribution Network with Soft Open Point

摘要

Soft open point (SOP) is applied to the power service restoration of the distribution network because of the advantages of flexible control mode and optimizing the operation of the distribution network. Taking advantage of parallel collaborative between independent peer smart terminals unit (STU) in distribution network and information interaction ways of working, distributed power service restoration method of distribution network considering soft open point is put forward, which brings the superiority of SOP in the aspect of power service restoration into full play and avoids the problem of large information collection and calculation in the centralized power service restoration method. Firstly, the structure, control mode and power service restoration model of SOP are introduced, and then the distributed power service restoration method of distribution network with SOP is described, which mainly includes distributed network topology search and the expression and calculation of constraint conditions. Finally, a numerical simulation is carried out to verify the effectiveness of the proposed method.
