Abstract The purpose of this paper is to present a comprehensive congestion management scheme based on generator and FACTS device operations. To relieve congestion effectively and quickly, we use two indices based on the DC method. However, calculation errors using the DC method may become large due to its approximations. Thus, we also developed an improved DC method, which is a DC method considering transmission losses and transformer tap ratios, and performed simulations to confirm the validity of the improved DC method. Finally, we performed simulations by the proposed congestion management scheme using the IEEJ EAST 30‐machine system. The simulation results indicate that congestion can be relieved effectively and quickly. © 2009 Wiley Periodicals, Inc.
