Abstract

Proper design and operation of transmission lines, known as transmission expansion planning, is known as the only efficient tool for optimization and continuous transmission of electrical energy to neighbor countries, affording economic and security interests to Iran. In order to achieve this goal, different items such as maintaining power system stability after the development of lines, the adequacy of lines after the end of the year planning horizon, are important. Along with the operation of the transmission network constraints and economic objectives, one of the concerns of passive defence is the determination of appropriate candidates to apply it to solving the problem of transmission expansion planning. In this paper, using the line stability indexes such as FSVI and Lmn indexes which are based on the load flow analysis, relation between passive defence and the transmission expansion planning has been created. Using these criteria, candidate lines which are used as input in transmission expansion planning methods, are determined.
