Article history: Received 28 October 2011 Accepted December, 5 2011 Available online 8 December 2011 Continuous generation of electricity of a power plant depends on the higher availability of its components/equipments. Higher availability of the components/equipments is inherently associated with their higher reliability and maintainability. This paper investigates the reliability, availabilit...

The general opinion about nuclear power plants is that they are not flexible generating units characterized with low or no load following capabilities. Therefore they should be used as baseline units only. Given the economic perspective of this issue, it is clear that the reasons for use of nuclear power plants as baseline units are purely economic. They have the lowest variable costs compared ...

In this paper, impacts of various uncertainties such as random outages of generating units and transmission lines, forecasting errors of load demand and wind power, in the presence of Demand response (DR) programs on power generation scheduling are studied. The problem is modelled in the form of a two-stage stochastic unit commitment (UC) which by solving it, the optimal solutions of UC as well...

This paper describes the use of tabular methods at Ontario Power Generation Inc. (OPGI) 1 on the Darlington Nuclear Generating Station Shutdown System (SDS) Trip Computer Software Redesign Project. We first motivate the selection of tabular methods and provide an overview of the Systematic Design Verification (SDV) procedure. After reviewing some preliminary concepts, the paper describes how th...
