The increasing load demand is pushing power system to operate near its limit, making it more vulnerable to various disturbances and attacks, especially those that might initiate cascading failures. In this study, the joint line-generation attack is introduced which assumes that the lines and generators can be tripped by malicious attacks simultaneously, and it is a natural extension of the previous...
Unified power flow controller (UPFC) is one of the most advanced flexible AC transmission system (FACTS) devices that can simultaneously and independently control both the real and reactive power flow in a transmission line. The utilization of UPFC can result in significant reliability benefits in modern power systems. This paper proposes a novel reliability network model for a UPFC, which incorporates...
Power flow tracing has been received more attention in recent years due to the situation of deregulation and open access in power industry. It is usually required to calculate the power transfers from individual generators to loads and branches, shares of each load and generation in branch flows. This paper proposes a novel power flow tracing technique using a directed path from buses to buses, which...
Non-coherence in system reliability refers to the fact that absence of a component from the system creates a more reliable system state or provides a higher system reliability level. This phenomenon may exist in transmission systems. Unfortunately, it has not been sufficiently recognized in the power industry. This paper explains the basic concept of non-coherence in transmission systems and provides...
