| Abstract | ||
| The we0 known and widely used power system model for the Load Frequency Control (LFCj problem is extremely linearized and approximated Over the,last three decades, extensive research efjorts have used such a model as a base for studying several control schemes in thisjeld Unfortunately, documented reports have proved that there exist many power systems worldwide sufjering from severe load-/requency jluctuations. Beside approximation and linearization, the uncertainty of the model parameters may consrittrte the main reasons of LFC failure. Unlike common control schemes, this paper presents a Fuzzy Logic-Based Load Frequency Controller. A. Variable Structure Fuzzy Controller (VSFCj will be developed to suite the power syslem ntodel for both wide range of parameter uncertainties and different types of disturbances. The performances of the proposed VSFC are compared with a conventional-LFC for a variety of system parameters and transient disturbances. This may highlight the effectiveness of the proposed controller not only solving the LFC problem but also in providing sufficient damping of the frequency oscillatiows. Another important objective of this paper is that it presents an easy tutorial to demonstrate the use of readily available computer sofiare(MATUB, SIMULINK, and Fuzzy Logic Toolboxj in the analysis and design of Load Frequency Control systems. | ||
