Fast textured algorithms for optimal power delivery problems in deregulated environments

For the future deregulated (open access) environments: we need to find the best way to deliver the electric power to buyers after the generation settings are determined by sellers' own economic strategies. In the paper, we will formulate such a problem as an Optimal Power Delivery (OPD) problem in terms of transmitted line flows and parameters of FACTS (Flexible AC Transmission Systems) devices, such as phase shifters and series compensators. The total transmission losses will be taken into account and represented by the transmitted line flows across those lines. Unwanted loop flow can be reduced or eliminated by FACTS devices and can be achieved by minimizing the total transmission loss. The OPD problem is then solved by two fast textured algorithms for modified IEEE 14-bus and 57-bus systems.
