Modeling Maintenance Scheduling Behavior of Power Units in Restructured Power Systems Based on Game Theory

Privatization of power sector and establishment of competition in power supplying process, raised unprecedented challenges in power system operation and planning fields, such as preventive maintenance scheduling which was formerly, in traditional environment, managed centrally by dispatching center. Dispatching center role having been changed in restructured power systems, power producing companies play a more important role in PM scheduling process. The conflict between dispatching center being concerned about power system reliability and stability, and power generating companies profit maximization based behavior which cannot be defined properly thorough traditional optimization theory, may be modeled satisfactory thorough Game theory approaches. In this paper, after modeling and solving PM scheduling process thorough game theory, discusses about resultant equilibrium states and predicts different power generation technologies behavior.
