Important Viewpoints of Maintenance Scheduling in Restructured Power
In a monopolistic power system, maintenance scheduling is being done only upon the technical requirements of power plants and preserving the grid reliability, while in restructured power systems, technical viewpoints and system reliability are taken into consideration in maintenance scheduling with respect to the economical viewpoints.
Coordination of Generation Maintenance Scheduling in Electricity
Generation maintenance scheduling (GMS) plays an important role in power system operations. The restructuring of the power industry has forced changes to the traditional maintenance mechanism. On one hand, the generation companies seek to maximize their profit. On the other hand, the independent system operator (ISO) strives to maintain the operational reliability of
Maintenance scheduling of power units in a restructured power system
Yearly maintenance scheduling of power generating units is an important scheduling problem that has to be solved within a restructured power system. Solving period of this problem usually is a one year basis. In this paper, a bi-level approach is used to solve maintenance scheduling problem. The upper level of this bi-level problem represents the profit maximization
Long-Term Generation Maintenance Scheduling with Integration
In restructured power systems, regard to the independence of generation companies, the procedure of maintenance planning has become more complicated compared with traditional power systems.

Multi‐objective optimisation of generation maintenance scheduling
2016. This paper presents generator maintenance scheduling of a power system based on minimization of the objective function considering the economical and reliable operation of a power system while satisfying the network constraints along with crew/manpower, generation limits, precedence constraints, demanded load, maintenance window, loss of load probability
A reliability-based approach for integrated generation and
Maintenance planning and reliability are closely related which affect each other in several ways. In traditional power systems, this issue is mostly modeled as reliability constraints in maintenance scheduling problem. In restructured power systems, different institutions have separated role in ensuring the reliability of the system and equipment.
Generation maintenance scheduling in restructured power systems
This paper addresses generation maintenance scheduling in a competitive electric energy environment. In a centralized setting, the system operator derives a maintenance scheduling plan that attains the desired reliability while minimizing cost and imposes it to all producers. In a competitive environment, this is not possible because the operator is still in charge of
Robust generation maintenance scheduling considering wind power
Generation maintenance scheduling has system level and equipment level aspects. At the system level, large-scale integration of wind power brings about significant challenges for classical generator maintenance scheduling. At the equipment level, forced outages of power equipment caused by wear affect maintenance decisions.

Maintenance Scheduling in Restructured Power Systems
The overall goal of this book is to introduce algorithms for improving the economic posture of a utility company in a restructured power system by promoting cost-effective maintenance schedules. Today, cutting operations and maintenance (O&M) costs and preserving service reliability) are among the top priorities for managers ofutility companies.
Iterative approach to generator maintenance schedule
Through iterations among power producers and the ISO, an appropriate schedule can be obtained to balance the producers'' benefits and the system operating costs. Note that the system operating costs consist of three terms of the reliability cost, the production cost, and the maintenance cost.
