Minimum cost control of real-time congestion management of electricity system

This paper studies the problem of congestion management model that based on quoted price adjustment in the real-time electricity markets, dealing with two cases : opening the generator side only and opening the generator side and load side simultaneously, introduces the congestion factor and establishes a novel optimal congestion cost model for each case. Furthermore based on the max-mini theory, changes the congestion management into a nonlinear programming problem that while the transmission congestion is maximum the adjustment cost is minimum. Finally the results of the simulation identify the simple feasibility and safe reliability of the proposed method.
