The conventional Bayesian framework of filtering is based on the assumption that the measurements are available at each time-step without any delay. But in real-life problems, measurements may be randomly delayed in time. In this paper, we modified the unscented Kalman filter (UKF) for arbitrary time delayed measurements. With the help of simulation results, it has been shown that the proposed filter...
Majority of electricity produced across world is from thermal power plants and they causes environmental pollution. With the increased awareness regarding environmental protection several countries has allotted share for electricity generation from wind power. As wind power is a clean energy, wind thermal integrated systems reduce emission. Wind integrated system are considered in this study along...
This paper presents a comparative study of dual material double gate junctionless transistor with the single material double gate junctionless transistor. A review of the basic modelling of the Junctionless transistor is also given in the paper. The surface potential of both structures are compared. The threshold voltage compared for both the devices shows that the single material gate has higher...
Offshore wind farms are becoming an attractive solution for wind power in many developed countries. The voltage source converter (VSC) based multi-terminal high voltage direct current (MTDC) transmission system is an attractive technical option to integrate these offshore wind farms with the onshore grid due to its unique performance characteristics and reduced power loss via extruded DC cables. In...
This study work is basically aimed at designing and testing of hardware module to perform inversion operation of a matrix in a small time. Here, an approach is made for calculating 3×3 matrix inverse. There are many mathematical methods available for performing matrix inversion and out of them a suitable method, like Adjoint Matrix Method is selected by analysing the computational requirements. The...
Solar PV is one of the demanding nonconventional sources for generation of electricity but it has its own limitation due to non-linear characteristics. Solar PV needs MPP tracker to extract maximum power form solar PV source. Furthermore, multilevel voltage source inverter (VSI) is used for converting dc voltage into closed to sinusoidal ac supply. In this paper, incremental conductance (IC) technique...
This paper presents modeling and simulation of isolated single phase supply system comprises of photovoltaic system tracked for its Maximum Power Point (MPP) and single-phase multi-level Voltage Source Inverter (VSI). The Maximum Power Point Tracking (MPPT) based on Perturb-and-Observe (P&O) technique is proposed for extracting maximum power from the photovoltaic module. Furthermore, single-phase...
Photovoltaic power plants pose some challenges when integrated with the power grid. The PV plants always focus on extracting the maximum power from the arrays. This makes the PV system unavailable for helping in regulating the grid frequency as compared to conventional generators. The objective of this paper is to introduce a pseudo power point tracking which provides frequency regulation functionality...
