23 Ιουν 2024 · Propagation of cascading failures can cause catastrophic events. Protective measures to prevent the agents from joining the cascade play an important role in controlling the cascade. In this...
30 Σεπ 2020 · Nodes of degree 0 are removed to avoid degenerate cases. We initiate a cascade by removing a single node, holding the selected (protected) nodes “safe from failure”.
1 Δεκ 2017 · The improved OPA model took into consideration the effects of dispatching, automation, communication, relay protection, operation mode and planning. Two metrics, Value at Risk and Conditional Value at Risk, were defined in order to evaluate cascading failures risks quantitatively.
This presentation reviews the established principles and the advanced aspects of the selection and application of protective relays in the overall protection system, multifunctional numerical devices application for power distribution and industrial systems, and addresses some key concerns in selecting, coordinating, setting and testing of smart...
8 Νοε 2023 · This chapter first draws insights from historical cascading and blackout events and then introduces the industrial practices and state-of-the-art technologies for prevention, and mitigation of cascading failures, and system restoration from blackouts.
To address this problem, this paper introduces a cascading failure model of a cyber physical power system (CPPS) that considers the operation characteristics of the communication layer,...
16 Μαΐ 2019 · The authors investigated the cascading failures in power systems described by the direct current power flow equations, where the initiating disturbances (natural or anthropic factors) give rise to changes in admittances of one or multiple transmission lines.
