Abstract

The purpose of this paper is to propose a comprehensive congestion management scheme by 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 propose an improved DC method, which is a DC method considering transmission losses and transformer tap ratios, and carry out simulations to confirm the validity of the improved DC method. Finally, we carry out simulations using the proposed congestion management scheme by means of the IEEJ EAST 30 machine system. With the simulation results, we can relieve congestion effectively and quickly.
