چکیده
This paper proposes Fuzzy Quasi Decentralized Functional Observers (FQDFO) for Load Frequency Control of inter-connected power systems. From the literature, it is well noticed about the need of Functional Observers (FO’s) for power system applications. In past, conventional Functional Observers are used. Later, these conventional Functional Observers are replaced with Quasi Decentralized Functional Observers (QDFO) to improve the system performance. In order to increase the efficacy of the system, intelligent controllers gained importance. Due to their expertise knowledge, which is adaptive in nature is applied successfully for FQDFO. For supporting the validity of the proposed observer FQDFO, it is compared with full order Luenberger observer and QDFO for a two-area inter connected power system by taking parametric uncertainties into consideration. Computational results proved the robustness of the proposed observer.

متن کاملLoad Frequency Control Based on Improved Fuzzy Controller in the Microgrid with Thermoelectric Generator
The Microgrid is a small-scale controlled power system, which can be used in islanded mode or in a grid-connected one to provide power. In the islanded Microgrid, the system frequency will be affected severely by the smallest disturbance which can happen due to light inertia in the system. In the independent Microgrid, several generation sources such as solar, wind, and so on can be considered....
متن کاملVoltage Control and Load Sharing in a DC Islanded Microgrid Based on Disturbance Observer
Increasing DC loads along with DC nature of distributed energy resources (DERs) raises interest to DC microgrids. Conventional droop/non-droop power-sharing in microgrids suffers from load dependent voltage deviation, slow transient response, and requires the parameters of the loads, system and DERs connection status. In this paper, a new nonlinear decentralized back-stepping control strategy f...
