Reliability Modeling and Assessment of Power Systems Containing HVdc Links

The increased utilization of HVdc technology around the world has created the need for evaluating the reliability of power systems that contains HVdc facilities. For example, if the generation system is remote and it is connected to the load centre through HVdc links, the transmission may have a significant impact on the overall system reliability performance. Most of the research described in the existing literature focus on analyses of simple example power systems to illustrate the concepts, models and techniques in probabilistic reliability assessment of HVdc systems. Relatively scant attention has been given to incorporate the existing models and techniques in large practical power system reliability evaluations. The proposed research is targeted to take the advantage of calculation accuracy of an appropriate available tool such as Risk_A to develop a consistent and comprehensive method for reliability assessment of power systems containing HVdc links using the existing tool. The approach will be based on the utilization, modification or enhancement of existing reliability models proposed in various literature.
