Integral Load Frequency Control (LFC) and Inter-Area Angle Separation Regulation
International Review of Electrical Engineering (IREE), 2020This paper presents the control of angular separation among the areas of a three-area electrical power system. This is achieved by the modification, upgrade, and adaptation of the existing load frequency control scheme. The purpose of this new control capability is to reverse the adverse effects caused by the progressive increase of angular separation ...

Load Frequency Control Method by Charge Control for Plug-in Hybrid Electric Vehicles with LFC Signal
IEEJ Transactions on Power and Energy, 2009In the power sector, total capacity of wind power generations has been increasing drastically. However, the wind power affects the power grid frequency and the tie-line flow adversely because of the instability of output. In particular, these problems become significant at nighttime when the capacity of Load Frequency Control (LFC) tends to be ...

DAR-LFC: A data-driven attack recovery mechanism for Load Frequency Control
International Journal of Critical Infrastructure ProtectionIn power systems, generation must be maintained in constant equilibrium with consumption. A key indicator for this balance is the frequency of the power grid. The load frequency control (LFC) system is responsible for maintaining the frequency close to its nominal value and the power deviation of tie-lines at their scheduled levels. However, the remote

This paper presents a coordinated load frequency control (LFC) scheme between the conventional LFC units and a small sized energy capacitor system with high power output. The fast charging/discharging operation is available on the ECS to balance the total power generation with the total power demand. The ECS can absorb the rapid variation of load power.

The Load-Frequency-Control (LFC) of the Energie-Versorgung Schwaben AG (EVS)
IFAC Proceedings Volumes, 1992Abstract As one of the nine interconnected utilities in Germany EVS operates an own LFC since April 1st, 1990. The autonomous control system is equipped with an own telemetry system and besides the control task it also covers some additional functions like monitoring the hydraulic plants, recording and disturbance diagnosis.
