Maintenance scheduling of generating units in restructured power systems is a collaborative and interactive process between independent system operators (ISOs) and generating companies (GENCOs). The ISO should comply with GENCOmaintenance preferences subject to targeted system reliability levels. This process might be multistage since the admission of all initial unit outage requests may threat...

The objectives of load frequency control (LFC) are to minimize the transient deviations in these variables (area frequency and tie-line power interchange) and to ensure their steady state errors to be zeros. Since the tieline interfaces give rise to weakly coupled terms between areas, the large-scale power system can be decentralized into small subsystems through treating tie-line signals as di...

in restructured power systems and in a wholesale power market, a distribution company as a market player intends to maximize its profit by utilizing its options. hence determining an optimal energy acquisition strategy for a distribution company is vital, for attaining to this goal. however an important challenge for determining these strategies is forecasting other competitors and generation c...

The integration of national electricity systems into a single internal European electricity market is not progressing well with the result that the level of competition in the sector remains unsatisfactory. This had led to proposals to apply ex ante remedies that directly bear on the structure of national incumbents. These measures involve quantitative recommendations such as virtual auctioning...

Installed capacity markets in the northeast of the United States ensure that adequate generation exists to satisfy regional loss of load probability (LOLP) criterion. LOLP studies are conducted to determine the amount of capacity that is needed, but they do not consider several factors that substantially affect the calculated distribution of available capacity. These studies do not account for ...

OBJECTIVES Leaders representing healthcare quality, purchasing, and certifying sectors convened at a national leadership meeting to address the issue of Healthcare-Associated Infections (HAIs). A session entitled "The Quality Choir: A Call to Action For Hospital Executives" featured harmonization partner organizations for the National Quality Forum Safe Practices (SPs) for Better Healthcare-200...

In this paper, a multi-area Automatic Generation Control (AGC) scheme with Renewable Energy Sources (RES) suitable in a restructured interconnected power system has been proposed. Photo-voltaic and wind turbine generating system has been integrated with the grid. The developed scheme has been investigated for frequency control with and without RES units. A PID controller has been used to contro...

Different equilibrium concepts have been proposed by various authors (Schweppe et al, Hogan, Chao and Peck, Wu et al) to analyse competitive electricity systems. We establish correspondences between these different models though a single framework and provide additional interpretations of these equilibrium concepts. This unifying conceptual view also provides a computationally feasible approach...
