A NOVEL ALGORITHM ON POWER SYSTEM SHORT TERM ECONOMIC AND SECURITY DISPATCH

Xia Qing; Zhang Boming; Kang Chongqing; Xiang Niande ;Song Yonghua (Dept. of E. E.,Tsinghua University Brunel University,United Kingdom )  
This paper proposes a novel algorithm to calculate the optimizing problem of economic and security dispatch in which DC power flow and capacity limitation on power transmission line is taken into consideration. Comparing with conventional Lagrangian Relaxation approach, the proposed algorithm is more effective in calculating speed, robustness, property of convergence and core memory requirement, without introducing any multiplier. A new and efficient way is prty posed to deal with more complex constraints in economic dispatch. The theoretical proof of algorithm is also given and the advantage of that is demonstrated by calculating IEEE 24 nedes system. Moreover, it has been proved that the result based on the proposed algorithm is the same as that on MATLAB.
