Stochastic Model for Preventing Blackouts

Abstract

Power system blackouts cause huge financial losses for the society and power utilities. Two types of blackouts have been identified. One involving load loss due to transmission lines reaching its limits and other involving failures of multiple transmission lines. Technologically advanced electricity transmission networks work in a financially just manner if a high rate of availability of the transmission networks is accomplished. Keeping this concept in mind, it is imperative to conduct the examination of transmission network availability, to design reliable electrical systems. This article discusses the stochastic availability modeling and analysis in transmission lines. The same is applied to a case of GED and the results obtained are discussed with the proper conclusion.

A Methodological Approach to Assessment and Reporting of the Model Adequacy in Simulation Studies

“…It models independent as well as dependent failures and repair modes (Yang & Dhillon, 1995;Sony Michael & Mariappan, 2012). Stochastic process of failure interaction in transmission was developed to account for dependent failures (Alsammarae, 1989;M Sony & Mariappan, 2019). One of the issues in Markov models are as the number of components to be modelled increases, the complexity of Markov model increases.…”

“…The tasks such as validation of precision, the accuracy of proposed simulation models form an important aspect. A wrong model can lead to erroneous conclusions, which can cost the stakeholders a large sum of money (M Sony & Mariappan, 2019). Besides simulation models can be used to communicate and advance the scientific knowledge, which in turn can lead to discoveries or challenging old discoveries or theories (Mac Nally, Duncan, Thomson, & Yen, 2018).…”
