Preventive Maintenance Scheduling of generating units is an important requirement in a power system planning. The maintenance of the various equipments in a power System, especially the maintenance of generators is directly related to the overall reliability of the power system. However, the Maintenance Scheduling (MS) problem is a constrained optimization problem. The objective function of this problem...
Genetic algorithm (GA) has shown its promise in dealing with reliability evaluation of complex power systems. However, it may be computationally expensive due to its stochastic search mechanism coupled with the problem complexity. Especially, when each system state needs a load flow calculation to determine its status, the reliability evaluation process may take a long time. Parallel computation is...
This paper presents the concepts for a novel locational reliability indices in electric power systems. The loss of peak load probability at every bus in the system is computed using the concept of commons and domains which determine the contribution of various generators to serving the load at a bus. A conceptual isolated load bus is formulated and the classical concepts of LOLP are extended to determine...
Maintenance scheduling plays a very important and vital role in power system planning. Any equipment irrespective of its size and complexity will have to be serviced periodically to ensure that the equipment does not fail to operate during normal operation. However, the maintenance-scheduling problem is a constrained optimization problem. The objective function of this problem is to reduce the loss...
