A Monitoring Technique for Reversed Power Flow Detection with High PV Penetration Level
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
The integration of renewable energy resources (RESs) in power systems poses many research challenges. Research shows that the RES output may exceed the consumed power during the day. Consequently, the direction of the power ...
Application of distance relay for distribution system monitoring
(
IEEE Computer Society
, 2015 , Conference Paper)
The traditional distribution network is primarily composed of radial feeders, designed for unidirectional power flow. Therefore, many operation regulation, protection and control system, in distribution network, are based ...
A secondary voltage regulation approach for Hydro-Québec in transmission level
(
Elsevier
, 2015 , Article)
This paper presents a secondary voltage control that applies discrete controllers to regulate the voltage in the Hydro-Québec power network. Firstly, an artificial intelligence methodology is presented for partitioning the ...
Control technique for enhancing the stable operation of distributed generation units within a microgrid
(
Elsevier
, 2015 , Article)
This paper describes a control technique for enhancing the stable operation of distributed generation (DG) units based on renewable energy sources, during islanding and grid-connected modes. The Passivity-based control ...
Modeling, impedance design, and efficiency analysis of quasi-Z source module in cascaded multilevel photovoltaic power system
(
IEEE
, 2014 , Article)
The quasi-Z source (qZS) cascaded multilevel inverter (CMI) (qZS-CMI) presents attractive advantages in application to photovoltaic (PV) power system. Each PV panel connects to an H-bridge qZS inverter (qZSI) to form a ...
A weighted real-time predictive controller for a grid connected flying capacitors inverter
(
Elsevier

(
IEEE
, 2013 , Conference Paper)
This paper proposes a weighted Real-Time Digital Feedback Control for a grid connected Distributed Generation (DG) system (gas turbines, fuel cells, photovoltaic, wind.). The DG source is connected to the grid through a ...
Towards ultra high frequency and high efficiency gate drive circuits
(2013 , Conference Paper)
Recent developments in semiconductor technology enabled developing converters with ultra high switching frequency to achieve high power densities which increased the complexity of designing optimized gate drive circuits. ...
Deadbeat control of Z source inverter with voltage ride-through capability
(
IEEE
, 2013 , Conference Paper)
This paper presents a Z source inverter connected to grid. The effect of voltage sags on ZSI will be studied when two different ac side control schemes are used. The paper compares the performance of both PI control and ...
Matlab/Simulink implementation & simulation of islanding detection using passive methods
(
IEEE
, 2013 , Conference Paper)
The extensive use of Distributed Generators in Electrical and power systems made it a must to explore its functionality and the issues related to their connection to the grid. One of the main issues is unintentional ...
