An energy management system model with power quality constraints for unbalanced multi-microgrids interacting in a local energy market
Johanna Castellanos, Carlos Adrian Correa-Florez, Alejandro Garcés +3
As multi-microgrids become readily available, some limited models have been proposed that study operational and power quality constraints with local energy markets independently. T…
A Convex Approximation for the Tertiary Control of Unbalanced Microgrids
Diego-Alejandro Ramirez, Alejandro Garces, Juan Jose Mora Florez
This article presents an optimization model for tertiary control in three-phase unbalanced microgrids. This model considers 24h operation and includes renewable energy sources, ene…
Gradient Formulation for the Stability of DC-Microgrids
Alejandro Garces
This paper presents a non-linear stability analysis for dc-microgrids in both, interconnected mode and island operation with primary control. The proposed analysis is based on the…
Wirtinger's Calculus for the Load Flow in Power Distribution Grids
Alejandro Garces
This short paper presents a Wirtinger's-Calculus based load-flow methodology for power distribution grids. This approach allows to obtain an algorithm which works directly on the c…
Analysis of Convergence for the Newton Method in DC Microgrids
Alejandro Garces
The power flow is a non-linear problem that requires a Newton's method to be solved in dc microgrids with constant power terminals. This paper presents sufficient conditions for th…
Stability Analysis in Type-A Wind Turbines: A Tutorial
Alejandro Garces
This tutorial presents a simple yet accurate transient stability analysis for Type-A wind turbines. The paper is presented in a tutorial way and therefore it includes some scripts…
