Abstract :
This paper discusses the problem of loss reduction by the means of reactive power redispatch. The idea is to keep the system security following a transaction. In this sense, identifying the generators most likely to play redispatch is crucial. A sensitivity-based methodology is proposed, so the generators are identified and their reactive power equations are incorporated into the ordinary power flow Jacobian, which yields a suboptimal solution. The tests are obtained with the help of the IEEE-14 bus test system with all limits taken into consideration.
