1 Abstract The network reliability analysis problem consists of evaluating a measure of the reliability of a network. A more general context than the network reliability analysis is the stochastic coherent binary system (SCBS) analysis. One approach used in determining the reliability of a system involves Boolean algebra, and in particular a sum of disjoint products (SDP) technique. This paper ...

reliability investigation has always been one of the most important issues in power systems planning. the outages rate in power system reflects the fact that more attentions should be paid on reliability indices to supply consumers with uninterrupted power. using reliability indices in economic dispatch problem may lead to the system load demand with high reliability and low probability of powe...

Placement of protection devices in a conventional feeder (without distributed generation) is often performed so as to minimize traditional reliability indices (SAIDI, SAIFI, MAIFIe...), assuming the sole source(s) of energy at substation(s). Distributed generation (DG) and storage units located on the feeder may be constrained in terms of power and/or energy capacity, and may include renewable ...

This paper proposes a novel approach to analyze the impacts of cyber layer failures (i.e., protection failures and monitoring failures) on the reliability evaluation of composite power systems. The reliability and availability of the cyber layer and its protection and monitoring functions with various topologies are derived based on a reliability block diagram method. The availability of the ph...

We introduce the notion of independent-disjoint analyses of Boolean functions. These analyses include both SDPs and OBDDs, and are well suited for network reliability computations.

Green and sustainable power is the need of the day. With widening supply and demand gap, power management has become one of the most critical areas of concern all over the world. India’s energy consumption is increasing at one of the fastest rates in the world. Hence, we require Substation Automation Systems in the present day substations to efficiently control and deliver power. The main objec...

Protection system failures have been recognized as major causes of expanded outages and thereby affect bulk power system reliability. With the rapid progress of smart grid technologies, legacy protection systems with hardwired architecture are being gradually replaced by computer and communication networks consisting of multi-functional and smart Intelligent Electronic Devices (IEDs). In this p...

in recent years, significant research efforts have been devoted to the optimal planning of power systems. substation expansion planning (sep) as a sub-system of power system planning consists of finding the most economical solution with the optimal location and size of future substations and/or feeders to meet the future demand. the large number of design variables, and combination of discrete ...
