Advanced Control Architectures for Intelligent MicroGrids, Part I:Decentralized and Hierarchical Control
This paper presents a review of advanced control techniques for microgrids. This paper covers decentralized, distributed, and hierarchical control of grid-connected and islanded microgrids. At first, decentralized control techniques for microgrids are reviewed. Then, the recent developments in the stability analysis of decentralized controlled microgrids are discussed. Finally, hierarchical control for microgrids that mimic the behavior of the mains grid is reviewed
New techniques for inverter flux control
Inverter flux control methods directly control the integral of the inverter output voltage vector, by means of the inverter switching. These methods have found applications in low- and medium-voltage industrial drives, and in inverters with outputs connected to the utility mains. This paper describes a new method for the direct control of the inverter flux vector, with the viewpoint of using this vector as the main forcing quantity in a closed-loop control system. It illustrates the use of the inverter flux in the control of a utility-connected inverter.IEE
A new public-domain simulator for power electronic circuits
A new public-domain simulator (SEQUEL) for power electronic circuits is described. The organization of the simulator is briefly discussed. The most important feature of the simulator is that the user can define new elements in a flexible manner. The differences between the new simulator and other simulators are enumerated. Some simulation examples are discussed to demonstrate the applications of the simulator. It is pointed out that the new simulator is particularly attractive for engineering institutes in developing countries where access to expensive commercial packages with similar capabilities may be difficult.IEE
