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.

A Comprehensive Review of Load Frequency Control Technologies

Energies
Load frequency control (LFC) is one of the most important tools in power system control. LFC is an auxiliary service related to the short-term balance of energy and frequency of power systems.

Demonstration of Frequency Regulation via Autonomous Load Control

IEEE Access
With the increasing proliferation of photovoltaic (PV) and wind power globally, frequency regulation by balancing generation and load in power systems is becoming increasingly difficult owing to reductions in dispatchable power and inertia.

Application of FESS Controller for Load Frequency Control [PDF]

Journal of international Conference on Electrical Machines and Systems, 2013
This paper presents the effect on application of the flywheel energy storage system (FESS) for load frequency control (LFC) of an interconnected 2 area power system. To do this, the control characteristics with the FESS were compared with that of the conventional governor controller.
