Available in PDF, EPUB and Kindle. Book excerpt: The power system is moving from a vertically integrated system to a restructured industry. Driven by the market competition, investors are very prudent in installing new facilities and the system is operated very close to the traditional limits. This causes difficulty for both facility owners and operation planners in scheduling maintenance for the power system. Cumulative risk assessment is a better tool than the deterministic method in the time frame of operation planning. Based on cumulative risk assessment, a cumulative risk reduction curve can be calculated for each maintenance task. Hence, the effect of a maintenance schedule can be related to system performance directly through risk reduction. In the light of this, a risk-based maintenance scheduling methodology is developed. It utilizes year-long simulations of hourly conditions, probabilistic risk-based security assessment, and heuristic techniques to solve optimization problem for scheduling generation maintenance and transmission maintenance as a function of risk reduction enabled by the maintenance. It can be used in scheduling maintenance for generator units and transmission facilities. It can be applied to a vertically integrated utility, and a restructured industry as well.
