The market power of the incumbents means that average pool prices are set by the costs of entry. Reforms which raise entry costs will be proposed and should be resisted. Reforms to capacity payments may have little effect on prices, but could affect system security. The values of VOLL and LOLP appear grossly incorrect, and if changed might affect reserve margins and the allocation of investment...

The risk associated with introducing wind turbines into the generation fleet is investigated in this paper. The loss of load probability (LOLP) and statistical expected demand not supplied (EDNS) are adopted as the risk indices. A case study is reported to evaluate the risk posed by displacing conventional generation with wind turbines. Results on the test system show that multiples of wind tur...

—In this paper, we present a modeling and simulation framework for conducting the adequacy assessment of a wind-integrated power system accounting for the associated uncertainties. A multi-perceptron artificial neural network (NN) is trained by a non-dominated sorting genetic algorithm–II (NSGA-II) to forecast point-values and prediction intervals (PIs) of the wind power and load. The output of...

In accordance with the specifications for the design of the gas station lighting system, the original lighting system was transformed into the overall solar-powered LED lighting system. The original lighting was replaced by using the same illumination LED lamps. Calculations were made to determine the optimum tilt angle of solar components. Based on the reasonable LOLP rate, solar module and ba...

This paper presents a methodology for maintenance scheduling (MS) of generators using binary particle swarm optimization (BPSO) based probabilistic approach. The objective of this paper is to reduce the loss of load probability (LOLP) for a power system. The capacity outage probability table (COPT) is the initial step in creating maintenance schedule using the probabilistic levelized risk metho...

-This paper reports a method to evaluate composite power system reliability indices incorporating the voltage stability margin criteria. To compute the load curtailment evaluation, an optimal power flow (OPF) computation algorithm, considering the steady state voltage stability margin constraint is developed. A steady state voltage stability indicator is first discussed for its applicability as...
