Long Term Preventive Generation Maintenance Scheduling with Network Constraints

Abstract

AbstractThe whole Electric Power System includes three aspects: Generation, Transmission and Distribution that all need maintenance to enhance system reliability and energy efficiency. Most unit maintenance scheduling (MS) packages consider preventive maintenance scheduling for generating units over one or two years time horizon in order to minimize the total operation costs while satisfying system energy requirements. The inclusion of network constraints in generating unit maintenance will increase the complexity of the problem. This paper mainly considers the generation maintenance scheduling taking into account the system security and reliability indices. For more realistic study transmission, security constraints as well as crew constraints and system reliability indices such as amount of not supplied energy are considered for the proposed maintenance scheduling problem. General Algebraic Modelling System (GAMS) is the utilized for solving optimization problem. An IEEE 24 bus test system is employed for simulation and show the accuracy of results
