Distributed Control of Microgrids

What is distributed control in microgrid?

Distributed control in microgrid allows the self-decision making of a DER based on the local measurements and limited communication with other DERs.

What are control strategies for microgrids?

Defining control strategies for microgrids islanded operation Overview of control and grid synchronization for distributed power generation systems Micro-grid autonomous operation during and subsequent to islanding process A control strategy for a distributed generation unit in grid-connected and autonomous modes of operation

What is decentralized microgrid control?

Specifically, decentralized microgrid control refers to that the operation and adjustment of DERs can be realized via local information only, and the distributed control allows limited communication between neighboring DERs, as shown in the middle and right subfigures of Fig. 1.

What is micro-grid autonomous operation?

Micro-grid autonomous operation during and subsequent to islanding process A control strategy for a distributed generation unit in grid-connected and autonomous modes of operation Internal model-based current control of the RL filter-based voltage-sourced converter

What is a microgrid and how does it work?

The concept of a microgrid [ 13] is introduced as a building block of the smart grid as a solution for reliable interconnection of distributed energy resource (DER) units. Thus a microgrid is presented to the host grid as a single controllable entity that provides power and/or ancillary services.

Should centralized control methods be integrated into microgrids?

Furthermore, centralized control methods would face issues of scalability. Integrating a deeper penetration of DERs into microgrid will not only increase the communication burden of MGCC, but also raise the complexity of centralized optimization, impacting the convergence rate of the coordination process.
