Frequency-based load control in power systems [PDF]

2012 American Control Conference (ACC), 2012
Maintaining demand-supply balance and regulating frequency are key issues in power system control. Conventional approaches focus on adjusting the generation so that it follows the load. However, relying on solely regulating generation is inefficient, especially for power systems where contingencies like a sudden loss in generation or a sudden change in

Load Frequency Control for Rural Distributed Generation [PDF]

Electric Power Components and Systems, 2010
In rural low-voltage networks, distribution lines are usually highly resistive. When many distributed generators are connected to such lines, power sharing among them is difficult when using conventional droop control, as the real and reactive power have strong coupling with each other.

An Investigation of Coordinated Attack on Load Frequency Control

IEEE Access, 2018
In this paper, optimal attack schemes against load frequency control (LFC) are studied by considering coordinated attack. By attacking sensor measurement (load) simultaneously, the attacker disrupts the normal operation of LFC, thus causing excess system

A Novel Control Scheme for Load Frequency Control

Majlesi Journal of Electrical Engineering
In this paper, a hybrid of Neural Network (NN) and Fast Traversal Filter (FTF) based controller is used to determine the optimal parameters of Load Frequency Control (LFC) of a realistic two area power system.

Output Regulation for Load Frequency Control [PDF]

IEEE Transactions on Control Systems Technology, 2022
Motivated by the inadequacy of the existing control strategies for power systems affected by time-varying uncontrolled power injections such as loads and the increasingly widespread renewable energy sources, this paper proposes two control schemes based on the well-known output regulation control methodology.

Fundamentals of load frequency control in power system

, 2023
Automatic generation control (AGC) plays a significant role in the control process in a power network to achieve the equilibrium between generation and load in the most cost-effective manner. Moreover, the AGC approach deals with frequency regulation and

Load Frequency Control in Variable Inertia Systems [PDF]

IEEE Transactions on Power Systems, 2020
Conventional load frequency control primarily relies on large synchronous generation units to ensure regulation of the system frequency. However, its performance deteriorates as the system parameters, including inertia and droop coefficients, deviate from original system design.

Hierarchical Control of Thermostatically Controlled Loads for Primary Frequency Support [PDF]

IEEE Transactions on Smart Grid, 2018
This paper proposes a hierarchical control of thermostatically controlled loads (TCLs) to provide primary frequency control support. The control architecture is composed of three levels. At the high level, an aggregator coordinates multiple distribution substations and dispatches the primary reserve references.
