Maintenance scheduling in the electricity industry: A literature review

Abstract

The reliability of the power plants and transmission lines in the electricity industry is crucial for meeting demand. Consequently, timely maintenance plays a major role reducing breakdowns and avoiding expensive production shutdowns. By now, the literature contains a sound body of work focused on improving decision making in generation unit and transmission line maintenance scheduling. The purpose of this paper is to review that literature. We update previous surveys and provide a more global view of the problem: we study both regulated and deregulated power systems and explore some important features such as network considerations, fuel management, and data uncertainty.

Optimal Hydropower Maintenance Scheduling in Liberalized Markets

“…Both hydropower scheduling [1], [2] and maintenance scheduling [3] are thoroughly addressed in the literature. The early works on scheduling of hydropower reservoirs used the principles of stochastic dynamic programming (SDP), see e.g.…”

Optimization of Generator Maintenance Scheduling with Consideration on the Equivalent Operation Hours

“…Most of the existing researches avert this problem by assuming that the maintenance schedules of CCGT generators are to be decided based on not the EOHs but the fixed period [2]. Researches on the generator maintenance scheduling with consideration on EOHs can be found in a limited amount of literature.…”

“…The objectives and technical considerations are a lot different according to the performers of the maintenance scheduling. The former put more focus on the overall system generation cost, maintenance cost or reliability [1,2], whereas the latter usually tries to maximize the generation company's profit [3]. In some countries, government supervises the maintenance scheduling for the stable electricity supply and the efficient operation of power system.…”

Strategic Maintenance Scheduling of an Offshore Wind Farm in a Deregulated Power System

“…A maintenance scheduling is performed in [29] by maximizing the reliability of a power system with wind generation where two wind particular constraints of wind variations and weather conditions are used. The recent work [31] reviews maintenance scheduling studies in the electricity industry and provides several propositions, such as modifying the models based on the regulated and deregulated systems, addressing price volatility, tailoring the objectives, which enhances strategic behavioral analysis in this area, and the addition of specific constraints for different types of power plants. For instance, currently, when a power system comprised of multiple power plant types is considered, maintenance schedules of wind power plants (regardless of their constraints) are handled similar to other power plants with one single maintenance schedule for the whole farm.…”

“…There are several studies addressing active preventive maintenance scheduling of wind farms in a network comprised of multiple types of power plants [28][29][30][31]. Research work [28] performs maintenance scheduling where particular wind power plant-related matters (e.g., varying wind) are neglected.…”
