A Procedure for Optimizing the Protection of a Transmission Network

摘要

A modularized procedure which provides heuristic solutions to optimization problems is applied to a transmission network which is considered as the union of a normal (nonrearrangeable) and a standby (rearrangeable) network. Module 1 routes requirements. Module 2 is the availability analysis of the normal network. Module 3 determines the total protection requirement in each failure condition to be met by the standby network. Module 4 is a standby optimization module in which all the rerouting flows determined in 3 are met at minimum cost. Total cost is represented as a function on the routing cost determined by changing the parameters which control the multirouting. Economically optimal solutions are obtained using a combination of protective measures.
