    The discovery of high-temperature superconductivity (HTS) in 1986-1988 rekindled interest in superconducting power transmission cables. Many projects are underway around the world to study the use of HTS power transmission cables. The siting and environmental issues facing the expansion of transmission capacity have become increasingly more difficult with time. The HTS power cable may be able to a... View full abstract»

    This letter presents a hybrid genetic algorithm (GA) method to solve optimal power flow (OPF) in power systems incorporating flexible AC transmission systems (FACTS). In the solution process, GA is integrated with conventional OPF to select the best control parameters to minimize the total generation fuel cost and keep the power flows within the security limits. A case study using an IEEE test sys... View full abstract»

    In this letter, the use of Monte Carlo analysis is introduced for calculating the current rating of high-pressure oil-filled (HPOF) pipe-type cable. It is shown that the current rating may differ by ±9.25% from its deterministic value if 10% variations in the random parameters of the cable system are assumed View full abstract»

    Security and reliability are major concerns in the deregulated and unbundled electricity supply industry due to the increased number of market participants and the changing demand patterns. This letter presents an approach and investigates the impact of incorporating dynamic security considerations in an open market environment. It is possible to reschedule the real power generation along with cur... View full abstract»

    The application of optimal reactive power flow (ORPF) to the New Brunswick (NB) power system is presented. The potential benefits and the real-time implementation problems of ORPF are discussed. Some important issues of real-time implementation on ORPF, such as frequency of running, the number of activated control variables, and the order of adjustment of different controls, are discussed. The app... View full abstract»
