Frequency and voltage control by decentralized controllable loads with fuzzy control
2011 IEEE International Conference on Fuzzy Systems (FUZZ-IEEE 2011), 2011In recent years, amount of renewable energy facilities using wind turbine generator and photovoltaic power system have been increased due to natural environment and resource depletion. Moreover, all electrification apartment houses or residences and electric vehicles have been increased.

Intelligent Load Control For Frequency Regulation In Microgrids
Intelligent Automation & Soft Computing, 2010Abstract During autonomous operation, MicroGrids may suffer large fluctuations in frequency due to the mismatch between load and local generation. The available spinning reserve might not always be enough to provide the required frequency support. Control of non-critical loads is able to provide the required primary and secondary frequency support. The

[Proceedings 1992] The First IEEE Conference on Control Applications, 2003
A technique for the control of frequency deviation in interconnected power systems is introduced. The technique is based on the application of linear feedback H-infinity robust controllers in the power system model. The controller response should be fast enough to offset the frequency errors due to load variations.

Unified PID design for load frequency control
Proceedings of the 2004 IEEE International Conference on Control Applications, 2004., 2005This work presents a new PID controller for power system load-frequency control. A systematic tuning method is developed. The method is mainly based on a maximum peak-resonance specification that is graphically supported by the Nichols chart. The proposed controller is simple, effective and can ensure that the overall system performance is desirable ...

Load frequency control incorporating time delay
Proceedings of the IEEE, 1987This letter discusses a load frequency control scheme incorporating the computation delay time in the control law. When there is a computation delay in determining feedback gains, the incorporation of the time delay is necessary for the improvement of dynamic responses. The influences of the delay time on the responses are investigated using a two-area

Decentralized load frequency control for load following services
2002 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.02CH37309), 2003This paper proposes a decentralized controller for the load frequency control operated as a load following service. Decentralization is achieved by developing a model for the interface variables, which consist of frequencies of other subsystems. To account for the modeling uncertainties, a local Kalman filter is designed to estimate each subsystem's ...

Application of Neural Networks to Automatic Load Frequency Control
Proceedings of The 2014 International Conference on Control, Instrumentation, Energy and Communication (CIEC), 2013The first theoretical analysis on PI controllers dates back to 1910. Even though the speed of response and overall stability of the system is slow, PI controllers are still used today. On the contrary, twenty first century customers, aware of power quality standards, demand faster response and very small settling.

Review of Various Load Frequency Controllers
2021In a power system, various fluctuations can occur in voltage and frequency due to the disturbances and sudden changes in the load (due to load change or fault). Whenever there is a change in the load, voltage and frequency get affected/disturbed. Voltage regulator is designed to compensate the voltage fluctuations and to compensate or maintain the ...

Control of load, frequency, and time of interconnected systems
Electrical Engineering, 1945The general problem is stated and typical solutions indicated. Characteristics of governors and of frequency- and load-control devices are briefly explained, and effects on generator and tie-line loads are summarized. Illustrating the principles enunciated, interconnected systems in southern Ontario and adjacent portions of Quebec totaling 1,650,000-kw
