Defining control strategies for MicroGrids islanded operation
TLDR
In this article, the feasibility of control strategies to be adopted for the operation of a microgrid when it becomes isolated is evaluated and the need of storage devices and load shedding strategies is evaluated.Abstract:
This paper describes and evaluates the feasibility of control strategies to be adopted for the operation of a microgrid when it becomes isolated. Normally, the microgrid operates in interconnected mode with the medium voltage network; however, scheduled or forced isolation can take place. In such conditions, the microgrid must have the ability to operate stably and autonomously. An evaluation of the need of storage devices and load shedding strategies is included in this paper.read more

Microgrids management
TL;DR: Depending on the type and depth of penetration of distributed energy resource units, load characteristics and power quality constraints, and market participation strategies, the required control and operational strategies of a microgrid can be significantly, and even conceptually, different than those of the conventional power systems.

Microgrid: a conceptual solution
Robert H. Lasseter,P. Paigi +1 more
TL;DR: In this article, the authors propose a system approach which views generation and associated loads as a subsystem or a "microgrid". During disturbances, the generation and corresponding loads can separate from the distribution system to isolate the microgrid's load from the disturbance (providing UPS services) without harming the transmission grid's integrity.

Control of parallel connected inverters in stand-alone AC supply systems
TL;DR: In this article, a control scheme for parallel-connected inverters in a standalone AC supply system is presented, which uses feedback of only those variables that can be measured locally at the inverter and does not need communication of control signals between the inverters.

Micro-grid autonomous operation during and subsequent to islanding process
TL;DR: In this paper, the authors investigated preplanned switching events and fault events that lead to islanding of a distribution subsystem and formation of a micro-grid, and they concluded that an appropriate control strategy for the power electronically interfaced DG unit can ensure stability of the microgrid and maintain voltage quality at designated buses, even during islanding transients.
