The paper presents a simplified approach to evaluate the risk index whose minimization results in the enhancement of power system reliability. The risk indices evaluated in the paper includes mainly LOLP (loss of load probability) and LOLE (loss of load expectation) with more emphasis on LOLE as it indicates the expected number of days in the specified periods in which the daily peak load will ...

Are required, but the resultant improved system reliability is often worth the price.advantages of the radial system in figure 2 but also gives greater reliability since the. The radial systems shown in figures 5-2 and 5-3 can be expanded by the. The loop system arrangement is one of several arrangements that can allow one. Typical equipment for this arrangement is low voltage power circuit-bre...

Power substations are intensively renovated toward using information and communication technologies such as object oriented modeling and Ethernet networks. In the last two decades, Substation automation systems used capabilities of network communication services adopted from sophisticated international standardizations such as IEC 61850. Distributed safety related functions take advantage of th...

Binary Decision Diagram (BDD) is a data structure proved to be compact in representation and efficient in manipulation of Boolean formulas. Using Binary decision diagram in network reliability analysis has already been investigated by some researchers. In this paper we show how an exact algorithm for network reliability can be improved and implemented efficiently by using CUDD - Colorado Univer...
