VSC with direct PI power control for frequency compensation in a microgrid: A PBC approach
(Institute of Electrical and Electronics Engineers Inc., 2019)
The power systems with low inertia such as microgrids require advanced control strategies to improve their performance. These type of grids use voltage source converters to interconnect renewable energy sources and storage ...
Wirtinger's Calculus for the Load Flow in Power Distribution Grids
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper shows a Wirtinger's-Calculus based loadflow methodology for power distribution grids. This approach allows to obtain an algorithm which works directly on the complex domain maintaining some useful symmetries and ...
Stability Analysis of Single-Phase Low-Voltage AC Microgrids with Constant Power Terminals
(Institute of Electrical and Electronics Engineers Inc., 2019)
This express brief presents the stability analysis of single-phase microgrids (SP-MG) operating under master-slave connection with constant power terminals. The SP-MG is composed of linear elements, nonlinear loads, and ...
A generalized passivity-based control approach for power compensation in distribution systems using electrical energy storage systems
