In this study we introduced a heuristic and powerful optimization technique called firefly algorithm to tune the coefficients of fuzzy-PID controller along with derivative filter (FPIDF) for the frequency control of a unified power system with thermal non-reheat type turbine. The response of system is observed under Step Load Perturbation (SLP) of 10% in area 1. The frequency stability analysis is carried on two phases. In the first case the system responses are analyzed by giving a perturbation of 10% in area 1 and in later case the system load is increased by 10% for verifying its robustness. The dynamic response of the FPIDF controllers are observed in terms of minimum undershoots, settling time and maximum overshoots. Further the results obtained by this established method are also compared with those of Bacteria Foraging Optimization (BFO) tuned PI controller and Hybrid BFO-PSO tuned PI controller which are published in previous journals.

The dynamic behavior of microgrid compromises the security and selectivity in conventional protection schemes. Islanding mode of operation provides continuous power supply to customers. Mesh configuration of microgrid can further improves the reliability. However, protection of mesh microgrid is a challenging task especially the isolation of faulted part only with rest of the system in operation. This paper presents a communication assisted protection scheme using negative sequence based voltage and current information of a microgrid. Using the change in angle difference of negative sequence voltage and current from pre-fault to fault case, method identifies the fault is internal or external. A hardware setup is established in the laboratory and performance of the relay algorithm is tested. Arduino uno microcontroller board is used as relay processor and XBee module is used for wireless communication.

Multilevel inverter (MLI) is an alternative for high power and high voltage applications. It has low switching stress on power switches, lower total harmonic distortion (THD), higher efficiency and low Electromagnetic Interference (EMI). Higher number of power switches contributes complexity of control and high cost. In this paper a five-level MLI is proposed with reduced switch count and improved performance. Optimal structures of this topology are investigated for interface with renewable energy resources. It uses single carrier and single input with hybrid modulation scheme. Proposed topology employs less power switches compared to that of conventional multilevel inverters. The digital simulation has been analysed and hardware prototype has been developed to validated the simulated results. The effect of DC voltage unbalancing and advantages of this structure is compared with conventional MLI topologies.

Energy trading in liberalized electricity markets is a decision-making problem that is modeled considering price uncertainty. Stochastic programming is a natural platform for modeling such decision-making problems, where uncertainties are characterized through scenarios. Scenarios are possible outcomes of random process with corresponding occurrence probabilities. A large number of scenarios are required for accurate modeling of any uncertainty. However, due to computational complexity and time limitations, generated scenarios are required to be reduced. This paper presents a efficacious algorithm for generation and reduction of electricity market price scenarios. Time series based Auto Regressive Moving Average (ARMA) model is used for scenario generation while Probability Distance Based Backward reduction method is utilized for scenario reduction. Proposed algorithm is illustrated through practical case study based on PJM day-ahead electricity market. Statistical analysis validates the proposed algorithm and comparison between ARMA and heuristic model for scenario generation reflect strength of proposed algorithm for modeling electricity market price uncertainty.

Axial flux brushless direct current motors (AFBLDC) are becoming popular in many applications including electrical vehicles because of their ability to meet the demand of high power density, high efficiency, wide speed range, robustness, low cost and less maintenance. In this paper, AFBLDC motor drive with single sided configuration having 24 stator poles and 32 permanent magnets on the rotor is proposed. It is driven by six pulse inverter that is fed from a single phase AC supply through controlled AC to DC converter. The speed control and braking methods are also proposed based on pulse width modulation technique. The overall scheme is simulated in MATLAB environment and tested under different operating conditions. A prototype of proposed AFBLDC motor drive is designed and fabricated. The control methods are implemented using DSC dsPIC33EP256MC202 digital signal controller. Tests are performed on this prototype to validate its performance at different speeds with and without braking mode. It is observed that the proposed scheme works effectively and can be used as wheel direct driven motor for electrical vehicle.

Variation of fundamental frequency components of current and voltage during power swing causes the error in phasor estimation. Due to this, many protection relaying schemes as distance, directional etc are badly affected and mal-functioned and this may lead to severe blackout. For series compensated line, the non linear behavior of metal oxide varistor (MOV), current and voltage reversal conditions, and sub-synchronous oscillations are also responsible for erroneous measurements of relay voltage and current during power swing. To overcome all these challenges, a fault detection scheme based on superimposed negative sequence apparent power is proposed which works during power swing for series compensated line. This scheme takes 3 ms-5ms for fault detection. Local end voltage and current data are utilized to execute the proposed algorithm. The 400kV, 50Hz WSCC 9 bus system is simulated using the PSCAD/EMTDC software.

Integration of wind generation into the existing power grids poses significant challenges. One of the major impact is transient instability in both transmission and distribution system. In this paper, the transient stability assessment of distribution system integrated with Doubly Fed Induction Generator (DFIG) as Distributed Generation (DG) is proposed. The optimal sizing and siting of DGs with loss minimization at their different Penetration Levels (PL) is obtained by Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) Techniques. The symmetrical faults at various locations are applied to the 33 bus radial distribution system to assess the transient stability of the system using time domain simulations.

Recent trends in the field of high voltage engineering attracts attention over the development of advanced electrical insulation systems. Electrical treeing due to highly divergent electric stress is one of the major threats to the electrical insulation. Once a treeing channel is incepted, it will lead to the propagation of electrical trees followed by insulation failure and electrical breakdown. Inclusion of nano-fillers in the base polymer(Epoxy resin) is found to resist the propagation of trees and improves the breakdown strength. This work attempts to study the effect of nano-fillers such as TiO2, ZnO, MgO with various filler concentrations for one gap distance. Test samples are made with needle plane electrode configuration to express the real time highly divergent electric field stress experienced by the cables. Neat epoxy samples were used as reference. High voltage AC at power frequency is the waveform used for the tests. The results show that Titanium oxide nano-composites exhibits higher breakdown strength than zinc oxide and Magnesium oxide nano-composites at 2 wt. % concentration. Further analysis of the results exhibits that 2 wt. % nano-fillers enhances while 1 wt. % worsens the electrical treeing resistance than neat epoxy.

The measurement and testing of 3D profile plays a vital role in characterizing orthopaedic bone plates. As being implanted in human body, its shape must be accurately defined in order to avoid harmful side effects. In present communication, we report a low-cost, non-destructive measurement of 3D surface profile of titanium bone plate using fringe projection and automated interferogram analysis technique. Collimated light from a He-Ne laser is incident on a grating and the resultant sinusoidal pattern is projected on bone plate sample. Resulting deformed fringe pattern carries the information of the sample surface. For measurement of 3D topographic information, interferograms are recorded and analyzed using Fourier transform method. The proposed setup provides its feasibility of being non-contact, non-destructive, fast, low-cost and robust against environmental perturbations.
