Abstract

Language:

The identification of critical transmission lines in a power system is vital for maintaining overall stability, reliability, and resilience. Traditional approaches relying mainly on static indicators like line loading and voltage deviations often fail to reflect the dynamic interactions and interdependencies within the network. This paper presents the Comprehensive Weight Method based on Game Theory (CWMGT), a novel technique that models the power system as a game in which each transmission line acts as a player. The method assigns a comprehensive weight to each line by combining local factors (such as loading, capacity, and performance indices) with global factors (such as connectivity, impact of failures on the network, and strategic interactions between lines). Lines are then ranked according to these comprehensive weights to identify those that are most critical. Simulation studies on realistic power system models demonstrate that CWMGT more accurately captures system dynamics and criticality than traditional methods, thereby supporting better decision‑making for maintenance, reinforcement, contingency planning, and risk mitigation by grid operators.
