The most frequent N-k line outages occur in motifs that can improve contingency selection [PDF]

open access: yes, 2022
Multiple line outages that occur together show a variety of spatial patterns in the power transmission network. Some of these spatial patterns form network contingency motifs, which we define as the patterns of multiple outages that occur much more ...

Power outages and firm performance: A hydro-IV approach for a single electricity grid [PDF]

open access: yes, 2021
We estimate the impact of power outages on firm performance using a hydro-instrumental variable strategy which integrates a river flow with a hydropower generation model and an electricity-grid-based distance interpolation technique. Comparing World Bank

Coping with power outages in mobile networks [PDF]

open access: yes, 2020
In a foreseen "post-peak" era, when oil production declines making energy price increase and leading to important economical implications descending from oil being the foundation of our industrial system, the development and maintenance of large ...

Dynamic Modeling of Power Outages Caused by Thunderstorms

open access: yes, 2020
Thunderstorms are complex weather phenomena that cause substantial power outages in a short period. This makes thunderstorm outage prediction challenging using eventwise outage prediction models (OPMs), which summarize the storm dynamics over the entire ...

The Most Frequent N-k Line Outages Occur in Motifs That Can Improve Contingency Selection [PDF]

open access: yes, 2023
Multiple line outages that occur together show a variety of spatial patterns in the power transmission network. Some of these spatial patterns form network contingency motifs, which we define as the patterns of multiple outages that occur much more ...

Constrained spectral clustering based methodology for intentional controlled islanding of large-scale power systems

open access: yes, 2015
Intentional controlled islanding is an effective corrective approach to minimise the impact of cascading outages leading to large-area blackouts. This study proposes a novel methodology, based on `constrained spectral clustering', that is computationally

Low‐Carbon Energy Transition and Corporate Carbon Emissions: The Critical Role of Climate Change Mitigation Policies and Institutional Context

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines the strategic efficacy of corporate low‐carbon energy transition, such as through nuclear energy adoption, as a response to decarbonization pressures. Analyzing an international sample of energy firms, we demonstrate that the relationship between this form of transition and emission reductions is not technologically ...

Techno‐Economic and Quasi‐Dynamic Load Flow Analysis of a Hybrid Renewable Microgrid for Coastal Industrial Loads

open access: yesEnergy Science &Engineering, EarlyView.
A hybrid PV–wind grid‐connected microgrid for Mongla Port is optimized using HOMER Pro and validated via DIgSILENT quasi‐dynamic load flow. The system achieves a low cost of energy (0.0341 USD/kWh), 70.9% renewable penetration, improved voltage stability, and significant emission reduction, demonstrating a reliable and cost‐effective solution for ...

Political Transition, Health System Reform and Trust in Childhood Vaccination in Ukraine: A Qualitative Case Study

open access: yesThe International Journal of Health Planning and Management, EarlyView.
ABSTRACT Trust in childhood vaccination is a concern for health policy, particularly in settings of political transition and conflict, where governance, institutional legitimacy and service delivery are often under strain. It is against this backdrop that this study aims to describe evolving interactions between health system governance, trust and ...
