Robust load-frequency control design for time-delay power systems [PDF]

, 2005
This paper addresses a control strategy to design a PIbased load-frequency control (LFC) in face of communication delays. First the PI-based LFC design is transferred to a static output feedback (SOF) control design and then to obtain the optimal PI ...

Novel efficient deep reinforcement learning-based load frequency control for isolated microgrid

AIP Advances
This study introduces a Learning-based Load Frequency Control (LB-LFC) approach to manage the challenges posed by renewable energy’s intermittency in microgrids, which often causes load disturbances, frequency fluctuations, and higher generation costs ...

Calculating the Interconnection Limit from a Comprehensive Voltage Evaluation for Distribution Systems with Large Distributed Energy Resources

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
Japan is pursuing power source decarbonization and is thus reducing fuel‐based thermal power generation while promoting renewable energy resource use. Given the expected power fluctuations, this transition will require novel voltage management and control methods.

An Adaptive Internal Model for Load Frequency Control Using Extreme Learning Machine [PDF]

, 2018
As an important part of a power system, a load frequency control has to be prepared with a better controller to ensure internal frequency stability. In this paper, an Internal Model Control (IMC) scheme for a Load Frequency Control (LFC) with an adaptive
