An optimal power delivery problem in deregulated open access environments

In this paper, we formulate an optimal power delivery (OPD) problem, in terms of transmitted line flows, for the future deregulated/restructured open access environments. It includes some FACTS (flexible AC transmission systems) devices, such as phase shifters and series compensators. The transmission losses are considered and are represented by the transmitted line flows across those lines. The problem can be solved by our fast textured decomposition algorithm. Moreover, the formulation takes care of the loop flow problem by minimizing the total transmission loss. Examples are used to demonstrate this point. We also show that the FACTS devices can be used to reduce the total transmission loss
