The objective of this paper is to deal with the problem of false convergence in the occasion of sudden drop of irradiance during limited power point tracking (LPPT) control of a photovoltaic (PV) system. In the case of LPPT control, the power output of a PV array is operating at a specified reference power level that is below the maximum power point (MPP). Because of sudden drop of irradiance, the power output of PV system may suddenly become zero and, subsequently, get stuck there unless the irradiance level is significantly raised again. The particular problem happens because of MPPT convergence detector that is used in existing LPPT controller in the case of power scarcity. Here, the new MPPT convergence detector is developed to avoid the false convergence problem. The proposed algorithm is compared with a conventional LPPT algorithm and tested through MATLAB simulation.

In this paper, a novel method based on the phase of noisy speech and noise signals is proposed. Phase ratio based two gain functions (G1 and G2) are developed and used for correction in noisy phase to suppress noises coming from angles 0 to ±π/2 and π/2 to ±π, respectively. For the reconstruction, both gains G1 and G2 were multiplied and lower values of the phases were neglected, which gives enhancement in speech. Objective speech intelligibility measures, informal subjective listening tests and spectrogram analysis were used for finding the effectiveness of the proposed method.

In this paper, a power flow method and an economic dispatch model of a microgrid with feeder flow control (FFC) distributed generators (DGs) are formulated. When FFC DGs are present, the microgrid exchanges a prescheduled amount of active and reactive power with the main grid, and therefore, the substation power is known a priori. Under such a circumstance, the conventional classification of the system buses into slack, load and generator buses is not sufficient, and the bus classification has to be extended. So, a new power flow technique capable of dealing with such a situation is formulated in this paper. Further, for economic load dispatch with system loss, penalty factors are required to be calculated. Calculation of penalty factors with FFC mode DGs is different from that in a conventional system. An analytical method of finding the penalty factors is also presented in this paper. The developed power flow and economic dispatch methods are validated on a test microgrid system.

This paper aims to investigates longterm variability of wind speed and wind power resource assessment using statistical based Weibull probability distribution approach. This research work has been carried out for the selected site Vijayawada located in the central region of Andhra Pradesh, India for the first time. In this context, the global Modern Era Retrospective Analysis for Research and Applications (MERRA) daily wind datasets has been considered for the long term analysis spanning over 36 years (1981–2016) at 10 m height a.g.l. Two-parameter Weibull probability and cumulative distribution models have been used to tap the wind power potential. Thereafter, an empirical method proposed by Lysen has been used to calculate the Weibull distribution parameters such as shape (k, dimensionless) and scale (c, m/s) factors. In addition, variations in wind speed characteristics namely mean wind speed (vm, m/s), maximum wind speed (vmax, m/s), most probable wind speed (vmp, m/s), maximum energy carrying wind speeds (vme, m/s) have been determined on the monthly, annual, seasonal basis. Finally, this work will help as guiding document for power and energy engineers, policy makers, as well as for researchers working in this area for providing solution to the problem of burgeoning gap between demand and supply of energy.

Type 3 wind generators like Doubly Fed Induction Generator(DFIG) are capable of providing reactive power support to the connected network. Thus interfacing them to the distribution network effects the voltage stability of the system. In this paper, the effect of the DFIG on an unbalanced distribution network has been evaluated using a voltage stability index calculated from power-flow analysis. The effect of different operating modes of DFIG at different wind speeds and different point of connection to the distribution network have been studied on IEEE standard 34 bus unbalanced distribution system. Effect of voltage regulators, tap limits and DFIG operating limits for unbalanced operation, on the system loadability has also been highlighted in this work.

The adoption of smart antenna system is a promise to the solutions of the wireless communication impairments like inefficient utilization of frequency spectrum, signal fading due to multipath propagation, etc. The smart antenna works in conjunction with digital signal processor which is responsible to adjust various parameters of the system in order to phase out interference signals and to enhance reception in the desired direction(s). In this paper, an attempt is made to develop various adaptive beamforming algorithms that lead to overall improvement in the performance of the smart antennas. Three complex adaptive beamforming algorithms like Complex Least Mean Squares (CLMS) algorithm, Augmented Complex Least Mean Squares (ACLMS) algorithm, and Adaptive Nonlinear Gradient Descent (ANGD) algorithms are considered for beamforming in smart antennas. Characteristics like Half Power Beam Width (HPBW), Side Lobe Level (SLL) and Mean Square Error (MSE) convergence rate and Tracking the desired signal are considered for the evaluation of performance of the smart array. Three new hybrid algorithms are proposed using the convex hybridization. The hybrid algorithm is formed by the convex combination of any two of the three algorithms in pursuit of performance improvement. The performance of these hybrid algorithms with respect to the important array characteristics is evaluated. It is identified that each of the three hybrids is superior to its individual filters.

This paper presents a modified Z-network half-bridge converter for applications that requires different kinds of load voltages such as varied positive or negative load voltage and varied time ratio between positive and negative load voltage. Compared to traditional Z-source half-bridge converter, the proposed converter reduces the Z-network capacitor voltage stress remarkably to realize the same load voltage characteristics, with same switch voltage stress. The operating principle, steady-state analysis, small-signal analysis, parameters design and comparison with conventional Z-source half-bridge converter is presented. Simulation results validates the effectiveness of theoretical analysis of proposed converter.

The onset of restructuring in the power system sector has led to the disintegration of the vertically integrated utility into three different individual entities, generating companies, transmission companies and distribution companies. In order to maintain the market efficiency, the allocation of the transmission cost is very vital. The framework of transmission pricing must be transparent and economical in order to maintain the reliable and efficient operation of the electricity market. A review on the latest era of the transmission pricing has been reported here. The importance of the transmission pricing and the allocation of the transmission cost using nodal pricing method and power flow tracing has also been discussed. This article also reviews the influence of transmission pricing on congestion management, the application of optimization techniques in the transmission cost allocation and the allocation of transmission losses along with a brief overview of the scenario of transmission pricing framework in different countries.

This paper presents a new idea about the development of line following algorithm for a differential drive mobile robot. The paper describes in detail this idea using Geometry to determine the radius of path curvature and based on it the desired difference between angular velocity of two wheels is calculated using Differential drive Kinematics. This robot uses an array of IR reflective sensors to find out the degree to which a circular arc deviates from a straight line. In this scheme a single PID controller is used to control the desired angular velocity for both wheels. To maintain the circular path of desired radius with constant linear velocity, the output of same PID controller is added in left wheel actuator and subtracted from right wheel actuator. Therefore the desired Radius of circular arc is followed by robot.

Porcelain Pin Insulators are one of the most critical components of Power system transmission and distribution arena. Due to environmental degradations these insulators get contaminated. Leakage current starts to flow over the surface of contaminated insulators in presence of humidity, light rain, fog, mist etc. This phenomenon ultimately leads to flashover. To prevent flashover, leakage current measurement of contaminated insulator is very essential. To measure leakage current of a contaminated insulator in presence of humidity of different levels, an experimental set up has been arranged at High Voltage Laboratory of Jadavpur University. From leakage current data and FFT analysis, it will be very helpful for prediction of contamination level of insulators and finally flashover will be averted.
