Conference Paper
Full-text available
An inverter is a power electronics circuit that can convert DC power into AC power. Inverters have a wide range of applications, from battery-powered devices to renewable energy systems such as photovoltaics. Typically, inverters rely on switching devices to create an AC signal. In most cases, these switching devices are arranged in the form of an...
Conference Paper
Full-text available
Due to the increased penetration in Distributed Energy Resources (DERs), especially in Photovoltaic (PV) systems, voltage and frequency regulation has become a topic of interest. Utilities have been requesting DER voltage and frequency support for almost two decades. Their request was addressed by standards such as the IEEE Std 1547-2018. With the...
Conference Paper
Full-text available
The high penetration of photovoltaic (PV) distributed energy resources (DER) facilitates the need for today's systems to provide grid support functions and ride-through voltage and frequency events to minimize the adverse impacts on the distribution power system. These new capabilities and its requirements have created concerns that autonomous unin...

Conference Paper
Full-text available
Photovoltaic (PV) inverters connected to electrical grids are required to detect and respond to Unintentional Islanding (UI) conditions appropriately. The IEEE Std 1547.1-2020 specifies test procedures, based on resonant parallel RLC loads, to evaluate the ability of PV inverters to detect and disconnect under UI conditions. This paper proposes a p...
Conference Paper

This paper presents an educational perspective into the Puerto Rico CubeSat Project and its objective in preparing undergraduate students into graduate level studies in the field of aerospace engineering. The Puerto Rico CubeSat is a joint effort between the NASA Puerto Rico Space Grant, the University of Puerto Rico-Mayagüez, and other educational...
Article
The positive-feedback-based anti-islanding schemes invented by the authors are highly effective in preventing islanding without causing any degradation in power quality. This paper presents the basic principles of these schemes and their design guidelines. Moreover, their performance is investigated for inverter-based distributed generators (DGs)....
Conference Paper
Recently proposed positive-feedback-based anti-islanding schemes (AI) are highly effective in preventing islanding without causing any degradation in power quality. This paper aims to analyze the performance of these schemes quantitatively in the context of the dynamic models of inverter-based distributed generators (DG). In this study, the charact...
Article
The formulation and computation of an optimal load shedding time algorithm is presented. This new concept was developed as an enhancement to the application of optimal load shedding for corrective control to support future islanded power systems with anticipated, enhanced communications infrastructure. The methodology combines nonlinear mathematica...
