Title:
POWER SYSTEM ANALYSIS DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2016/006091
Kind Code:
A1
Abstract:
If a change occurs in the configuration of a power system, it becomes necessary to rewrite a power equation that is a mathematical model, and load flow calculation cannot be continued in response to other power system structures (a mesh structure, a tree structure, or the like) or dynamic reconfiguration. Accordingly, the present invention is a power system analysis device that analyzes a power system configured on the basis of a plurality of nodes and branches that connect the nodes, said power system analysis device being characterized by the provision of: a means for calculating a load power that represents the power on a load side that is connected to the nodes; a means for calculating the complex voltage gradient of the branches on the basis of the load power; a means for calculating, on the basis of the complex voltage gradient, a correction amount for the complex voltage of an adjacent node that is connected to the nodes via the branches; and a means for calculating the correction amount for nodes within a predetermined range in the power system.
