The use of power electronic devices injects harmonics into the grid causing serious power quality problems. To limit the current harmonics in accordance with IEEE Std 519, Shunt Active Power Filter (SAPF) may be used. Instantaneous power theory (pq theory) is widely used for current harmonic mitigation in SAPF. The Low Pass Filter (LPF) is used in pq theory based controllers for fundamental component extraction. The drawbacks of LPF are additional phase delay at the fundamental frequency and presence of lower frequency oscillations. A dual Self-Tuning Filter based controller is proposed to overcome these limitations. The simulation studies under different system conditions are carried out using MATLAB/SIMULINK to verify the effectiveness of the proposed method. The hardware cosimulation using ZedBoard Zynq-7000 Development Board is carried out to validate the simulation results.

In large scale wireless sensor networks, energy consumption and optimization are a major challenge. Most of the protocols designed for cluster based routing problems suffer from unbalanced energy consumption. In this research work, an energy efficient clustering and routing protocol has been devised. An improved cuckoo search algorithm which uses a novel multiobjective fitness function have been proposed for optimal cluster head selection. Further, Monkey search algorithm has been used to find the optimal path from the cluster head to the sink nodes. The algorithm has been compared with some existing metaheuristics and significant improvements in number of alive nodes, energy efficiency has been observed.

In this paper, 3-level boost converter based micro hydel power generation system is proposed for DC micro grid applications. Three level boost converter is designed to operate at discontinuous conduction mode (DCM) to obtain high power factor operation even at variable input frequencies as the water head varies. Compared with passive PFC, active PFC reduces the filter size. In addition to this, DCM PFC correction scheme have an advantage of having no current sensor and multiplier in control loop. 3-level boost converter provides high voltage gain which is easily adapted for high power applications with lower sized inductor compared to the conventional boost converter. The balancing of voltage across the two output capacitors can be obtained by simple PI controller.

The present work features designing of a model predictive controller for the application of automatic generation control of a two area interconnected power system consisting of thermal, hydro and wind power generation units. Different Automatic Generation Control (AGC) strategies can be used to maintain the system frequency within the prescribed limit. Model Predictive Control (MPC) is such a modern control technique which works on an iterative finite horizon optimization of a model. MPC does not allow current time slot to be optimized while keeping the future time slots in mind. The coordination of control and set points is another unique feature of MPC. This paper presents performance comparison of MPC based automatic generation controller with conventional classical PI and PID automatic generation controllers. Comparative study reveals that proposed MPC provides better dynamic response for the mentioned system in terms of settling time, peak undershoot and peak overshoot.

This paper proposes a non-linear problem for the extraction of parameters in a solar photovoltaic system. As many of the optimization algorithms used so far does not work at the low irradiance level a novel approach of parameter extraction using a gravitational search algorithm is presented. At different irradiance level, different parameters of various PV panels are evaluated. The results and critical evaluation of MGSA optimization approach are then compared with genetic and gravitational search algorithms. The simulation MATLAB output confirms the suitability of the MGSA for parameter extraction of solar PV panels.

This paper forthputs the feasibility of wifi channel state information for suspicious object detection. The system can be used at public places such as stadiums, schools or museums. Various other methods for suspicious object detection (such as surveillance cameras, surveillance videos) are proposed earlier but these methods cannot identify the suspicious material inside the bags without violating people’s privacy. Our method proposes an algorithm to detect the suspicious objects in the baggage without invading privacy.

The multilevel inverter has applications in various areas. Now a days , multilevel inverters have wide scope in advancement of electric vehicles, static var compensators, photovoltaic purpose, interfacing with Renewable energy system.This paper proposes topology of multi level inverter with cascaded H-bridge which has several advantages over flying capacitor and neutral point clamped topology with the pulse width modulation (PWM) application. This topology can be used to increase number of level of output voltage by increasing number of input DC sources in appropriate manner. VFISPWM modulation method is proposed in this paper. In this switching method two signals are used with one is sinusoidal and other is inverted sine with variable frequency for reference and carrier signals respectively. The simulation results represents that the Total Harmonic Distortion (THD) for voltage is reduced with VFISPWM technique. The results of MATLAB simulation shows that fundamental voltage component gets improved with the significant reduction in THD as compared to Constant Frequency Inverted Sine PWM (CFISPWM)method.
