Title:
METHOD OF DETERMINING LOAD INTERCHANGE PATTERN IN DISTRIBUTION SYSTEM
Document Type and Number:
Japanese Patent JP3781522
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently determine an optimum load interchange pattern in accordance with a all-purpose program, regardless of a system by utilizing taboo-search.
SOLUTION: In a system expressed radially through sections surrounded by switches and power supplies, power feeding sections are radially and determined in probabilities taking the spare feed powers and capacities of the power supplies into account and a load interchange pattern in a state such that the power supplies are determined for all the sections is transformed into the state expression of the system for generating an initial state (Step S1). Further, the power supply direction of one load in the present radial system is changed for generating a plurality of adjacent states which are candidates of a next search point (2nd step S2). The adjacent state which is not in a taboo list and obtains the highest evaluation is selected from among a plurality of the adjacent states which are candidates of the search point as a next state, and at the same time, the present state is stored in the taboo list (3rd step S3). The step S2 and the step S3 are repeatedly executed until finishing conditions are satisfied and the optimum load interchange pattern is determined.
