Security constrained optimal reactive power dispatch

Electric Power Systems Research, 1989
Abstract This paper presents a systematic methodology to allocate reactive power devices in a power system. This is achieved through the application of an active set analysis based linear programming technique. The procedure takes into consideration outages which cause voltage problems and also existing reactive power controllers are fully utilized ...

Evolutionary computation based reactive power optimization

IET-UK International Conference on Information and Communication Technology in Electrical Sciences (ICTES 2007), 2007
Reactive power optimization (RPO) is an important technique which is concerned with the security and economy of operation of a power system. It uses all the reactive power sources judiciously, while planning suitable location and size of VAr compensation in a system.

Multi-areas optimal reactive power flow

2008 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America, 2008
This paper describes a method for the decentralized solution of the optimal reactive power flow (ORPF) problem in interconnected power systems. The ORPF model is solved in a decentralized framework, consisting of regions, where the transmission system operator in each area operates its system independently of the other areas, obtaining an optimal ...

Optimal real and reactive power dispatch

Electric Power Systems Research, 1984
Abstract This paper presents a method for optimal real and reactive power dispatch for the economic operation of power systems. As in other methods, the problem is decomposed into a P-optimization module and a Q-optimization module, but in this method both modules use the same generation cost objective function.
