Systems Level Validation of a Distributed Frequency Control Algorithm

Abstract

Distributed control and optimization strategies in power systems are gaining more and more attention, especially with the increasing penetration and integration of distributed generation. These novel distributed control and optimization algorithms need to be rigorously validated before their widescale deployment and acceptance. In this paper, a testing rig comprising real-time simulation with control and power hardware in the loop capability, with a multi-agent system platform and realistic communications emulation is utilized for the systems level validation of a distributed frequency control algorithm. The distributed frequency control is implemented within an islanded microgrid and its performance under two disturbances is assessed under real-world conditions. Index Terms-distributed control, multi-agent system, realtime simulation, power hardware in the loop, frequency control.

Multi-Agent System with Plug and Play Feature for Distributed Secondary Control in Microgrid—Controller and Power Hardware-in-the-Loop Implementation

“…The "Plug and Play" capacity is realized at the agent layer, as the system will automatically adapt to the alteration of topology (integration of new agent or removal of an agent) and react accordingly to maintain seamless operation. • The proposed distributed secondary control is implemented in a laboratory platform based on the propose in [18] with controller and power-hardware-in-the-loop (C/PHIL) setup, incorporating realistic communications network with the impact of uncertainties considered. The performance of system under realistic condition shows that the agents are able to resist to disturbances and to self-configure under alteration of grid topology.…”
