    All power systems, however well regulated and designed, do experience a deficiency of generation, resulting in operation at a reduced frequency. In this letter, we provide power flow and transient stability simulation results of our investigations on a five-bus 50 Hz sample power system when it is operating at a reduced frequency of 48.5 Hz View full abstract»

    Standard reliability indexes such as SAIDI ignore the variation in interruption costs with customer type. Thus, expenditure decisions driven by these indices that impact reliability, will not lead to the optimum improvement in value of service to customers. An index equal to customer interruption costs divided by energy sales (CICs/kWh) overcomes this deficiency. It is equally useful for identifyi... View full abstract»

    The electricity supply industry in England and Wales (E&W) was restructured and privatized on Vesting Day, 31 March 1990. Eight years on, the UK government has reviewed the trading arrangements of the E&W electricity market and accepted the regulator's proposal of replacing the day-ahead market (the pool) by several forward markets, a short-term bilateral market, and a balancing market. Th... View full abstract»

    Our objective here is to determine possible bifurcations in a one-machine-infinite bus (OMIB) power system model incorporating a TCSC. We develop from first principles the essential dynamic equations of the system. This approach identifies the bifurcations in the system View full abstract»
