Abstract

The development of new technology and changes in the climatic conditions brought some new methods in the generation of power. Along with these came the advancements of communication and control infrastructure of cyber which along with the traditional power system infrastructure, plays a vital role in delivering power to the customers. The main aim of the utility is to satisfy the customer’s need with uninterrupted power supply throughout the year. The power distribution system experiences 70%-80% of power outages due to failure of the component. To reduce the failure in a radial distribution system, it is necessary to evaluate the reliability of the system accurately at the planning stage. This becomes a concern as the traditional power reliability evaluation does not include the cyber equipment induced failures. In this work a new Boolean algebra based cyber-power interdependency modeling is proposed for reliability evaluation of cyber-enabled power system. This thesis discusses the problems in evaluating the reliability of a cyber power system and different methodologies proposed in the literature. Also, the proposed method is used to evaluate the reliability of Bus 2 of Roy Billinton Test System and obtained results show the significance of cyber-power dependency modeling for system reliability evaluation. Furthermore, the proposed method is compared with an existing technique to show the efficiency in terms of execution time.
