An Improved Voltage-Shifting Strategy to Attain Concomitant Accurate Power Sharing and Voltage Restoration in Droop-Controlled DC Microgrids
Waner Wodson A. G. Silva;Thiago R. Oliveira;Pedro F. Donoso-Garcia
This article proposes a distributed secondary level control strategy for dc microgrids, which achieves accurate and proportional power sharing and dc-bus voltage deviation restoration based on voltage shifting. In contrast to similar approaches, only one variable per converter is transmitted in the low-bandwidth communication link and with a simple integrator as the secondary level controller both...Show More
Model-Free Energy Management System for Hybrid Alternating Current/Direct Current Microgrids
Danilo I. Brandao;Rhonei P. dos Santos;Waner Wodson A. G. Silva;Thiago R. Oliveira;Pedro Francisco Donoso-Garcia
A hybrid ac/dc microgrid combines the benefits of ac and dc power systems. It provides high efficiency and is compatible with conventional ac distribution network. This article proposes a centralized energy management approach to perform coordinated control on a hybrid ac/dc microgrid as a single-controllable entity. The central controller relies on low-bandwidth communication channels and is aime...Show More
PLL-Based Feed-Forward Control to Attenuate Low-Frequency Common-Mode Voltages in Transformerless LVDC Systems
Thiago R. Oliveira;Waner Wodson A. G. Silva;Seleme I. Seleme;Pedro F. Donoso-Garcia
Low-voltage dc distribution systems have gained significant attention over the last years, since they provide simpler and more efficient integration of distributed generators and storage devices, establishing a pathway to net zero energy buildings. In low-power units, transformerless utility interface is preferred to reduce footprint and losses. However, the lack of galvanic isolation introduces a...Show More
A comparative study of Droop Compensation Functions for State-of-Charge based adaptive droop control for Distributed Energy Storage Systems
Frederico L. F. Marcelino;Hans H. Sathler;Waner W. A. G. Silva;Thiago R. de Oliveira;Pedro F. Donoso-Garcia

DC microgrid applications normally use Distributed Energy Storage Systems (DESS) to smooth out energy balance due to the non-dispatchable characteristics of renewable resources. Since the State of Charge (SoC) of each energy storage unit (ESU) can differ significantly SoC based adaptive droop control methods for SoC equalization has been proposed in literature. A droop compensation function is use...Show More
