The observability and controllability metrics of power system oscillations and the applications

Frontiers in Energy Research, 2023
Power system oscillation has caused many serious accidents in renewable energy grid connection system. The concept of observability and controllability in control theory has been widely applied to power system oscillation study.

Stability Metric Based on Sensitivity Analysis Applied to Electrical Repowering System

Energies, 2021
Stability metrics are used to quantify a system’s ability to maintain equilibrium under disturbances. We did not identify the proposition of a stability metric using sensitivity analysis within the literature. This work proposes a system stability metric

A Comprehensive Model for Quantifying, Predicting, and Evaluating Ship Emissions in Port Areas Using Novel Metrics and Machine Learning Methods

Journal of Marine Science and Engineering
Seaports, as major transportation hubs, generate significant air pollution due to intensive ship traffic, directly affecting local air quality. While emission inventories are commonly used to manage ship-based air pollution, they reflect only the ...

Critical review of the levelised cost of energy metric

South African Journal of Industrial Engineering, 2016
The purpose of this paper is to critically review the ‘levelised cost of energy’ metric used in electricity project development. This metric is widely used, because it is a simple metric to calculate the cost per unit of electricity for a given ...

Some Fixed-Point Theorems over a Generalized F-Metric Space

Advances in Mathematical Physics, 2021
In this article, the concept of sequential F-metric spaces has been introduced as a generalization of usual metric spaces, b-metric spaces, JS-metric spaces, and mainly F-metric spaces. Some topological properties of such spaces have been discussed here.
