Networked Microgrids for Improved Resilient Operation: A Case Study in Adjuntas Puerto Rico
This paper presents a case study of a network microgrid orchestrator designed to allow coordinated operation of microgrids. Through Control Hardware in the Loop (CHIL), the proposed microgrid orchestrator was validated using, as case study two community-owned microgrids in Adjunta...

Load Control for Frequency Response A Literature Review
As electricity grids employ greater fractions of renewable energy, which introduce additional variability and uncertainty in the net-load, balancing electrical load and generation becomes more challenging. This paper reviews the literature documenting physical simulations and real...

Use of Traveling Wave Signatures in Medium-Voltage Distribution Systems for Fault Detection and Location
Protection systems are a critical feature for the proper operation of a power grid. Protection systems should be able to quickly detect, identify, locate, and isolate the faults within a time frame that prevents damage to grid components and reduces customer outages. As more inver...

Inverter Controls for Smooth Transition Operation of Networked Microgrids
Islanding sections of a distribution grid as microgrids and networking these microgrids offer promising opportunities for improving system reliability; however, this approach may need distributed energy resources (DERs) to switch between grid-connected and islanded operation witho...

Study of Inverter Control Strategies on the Stability of Microgrids Toward 100% Renewable Penetration: Preprint
This paper investigates microgrid transient stability with mixed generation synchronous generator (SG), grid-forming (GFM) and grid-following (GFL) inverters under increasing penetration levels toward a 100% renewable generation microgrid. Specifically, the dynamics of a microgrid...

A Data-Driven Passive Islanding Detection Scheme
This paper proposes a novel statistical parameters based data driven approach for passive islanding detection. The proposed scheme relies in the voltage data, measured at the point of common coupling, and is comprised of three stages. The Stage-1 quickly detects what is termed as ...

Dynamic Shaping of Grid Response of Multi-Machine Multi-Inverter Systems Through Grid-Forming IBRs: Preprint
We consider the problem of controlling the frequency response of weakly-coupled multi-machine multi-inverter low-inertia power systems via grid-forming inverter-based resources (IBRs). In contrast to existing methods, our approach relies on dividing the larger system into multiple...
