Journal ArticleDOI
Assessing Impact of Renewable Energy Integration on System Strength Using Site-Dependent Short Circuit Ratio
TL;DR: In this paper, the authors proposed a site-dependent short-circuit ratio (SDSCR) to analyze the relationship between system strength and voltage stability in renewable energy sources (RESs).
Journal ArticleDOI
Nonlinear Dual-Mode Control of Variable-Speed Wind Turbines With Doubly Fed Induction Generators
TL;DR: This paper presents a feedback/feedforward nonlinear controller for variable-speed wind turbines with doubly fed induction generators that simultaneously enables control of the active power in both the maximum power tracking and power regulation modes.
Journal ArticleDOI
Fast Assessment of Frequency Response of Cold Load Pickup in Power System Restoration
Diego Rodriguez Medina,Edward Rappold,Omar Sanchez,Xiaochuan Luo,Sergio Raúl Rivera Rodríguez,Di Wu,John N. Jiang +6 more
TL;DR: In this article, the authors introduce an approach for a fast assessment of the dynamic characteristics of system frequency during the period of cold load pickup following a large-scale blackout following a blackout.
Proceedings ArticleDOI
Voltage stability and sensitivity analysis of grid-connected photovoltaic systems
TL;DR: In this paper, the static and transient voltage characteristics at the point of common coupling of a grid-connected photovoltaic system are analyzed and a method of voltage stability sensitivity analysis is presented for comparison between the impacts of different parameters on voltage stability.
Proceedings ArticleDOI
