Load-frequency control is the intrinsic function of the governor in the power plants. It would be used in variant structures depend on the controller type such as PID, adaptive, fuzzy or robust. Temporary droop structure governor (TDSG) was commonly used in hydro power plants (HPP). After representation of TDSG, this paper is dedicated to introducing a procedure for tuning TDSG parameters. The technique...
The governor of hydro power plants should track frequency variations and at the same time provide good response to load disturbances. These two functions are contradictory and the system model changes with the operating point. This paper presents a robust fuzzy logic adaptive load-frequency controller for hydro power plants. The case study is Abbaspour power plant in Iran.
One of the important requirements for operational planning of electrical utilities is the prediction of hourly load up to several days, known as short term load forecasting (STLF). Considering the effect of its accuracy on system security and also economical aspects, there is an on-going attention toward putting new approaches to the task. Neuro-fuzzy modeling has played successful role in various...
Short term load forecasting (STLF) plays an important role for the power system operational planners and also most of the participants in the nowadays power markets. Data used for STLF is mostly historical hourly load and weather parameters. Hourly load data is subject to errors made by instruments and/or operators and also unwanted or unplanned changes in the power system. In this paper, an approach...
