Power system reliability planning practices in North America

Abstract

This paper presents selected results from a recently completed research project for the Electric Power Research Institute. One component of the project was intended to develop and test methodologies for gathering data on how utility customers value service reliability, as measured by either the cost of outages or the willingness to pay for reliability. Another component of this project involved a survey of current and emerging reliability planning practices in the North American utility industry, especially regarding interest in "value-based reliability planning." The paper highlights the results of the survey, including the survey design and methodology. It also briefly discusses potential applications of interruption costs in generation and composite system reliability planning.

Parallel contingency analysis solution based on OpenMP

“…The run time of a parallel program is the time that has elapsed from the moment the first process actually begins execution to the moment the last process completes execution of its last statement. Speedup is calculated in the form of: S= t1/tn (1) According to Amdahl's law, the speedup of a parallel application using n processors is estimated in the form:…”

“…Security is the ability of a power system to withstand disturbances, in other words, to remain intact even after equipment outages or failures [1]. Security plays a crucial role in the planning and operation of a power system.…”

Probabilistic resource planning with explicit reliability considerations

“…The well known Loss of Load Probability (LOLP) in general denotes only the probability of generation capacity shortage [4].…”

Estimated Value of Service Reliability for Electric Utility Customers in the United States

“…For example see: (Munasinghe, 1979), (Burns and Gross, 1990), (Sanghvi et al, 1991), (Allan and Billinton, 1992), (Sullivan et al, 1996), (Sullivan and Keane, 1995), , , , (Woo and Train, 1988), (Matsukawa and Fujii, 1994), (Dalton et al, 1996), (de Nooij et al, 2006) and2008), (Ghajar and Billinton, 2005), , (Wangdee and Billinton, 2004), (Reitz and Sen, 2006) and (Rose et al, 2007) (LaCommare andEto, 2006) Value-based planning is designed to match the level of investment in reliability with the societal benefit of the improvement in reliability. The use of value-based planning requires a method for estimating customers' economic value of service reliability.…”
