This paper investigates, load frequency control (LFC) of nonlinear multi area system with hydro thermal units. Secondary controller adopted for test system model is double derivative (DD) with proportional (P) plus integral (I) (PIDD) controller, whose gains are optimized with grey wolf optimization (GWO) subjected to performance index minimization of error squared over integral (ISE). However, functioning of PIDD is compared with other classical controllers to reveal the superiority. Test system is investigated by subjugating area-1 with a load change of 0.01pu.MW. Later, the system is incorporated with plug in electric vehicles (PEVs) to regulate the system frequency further. Finally, HVDC link is amalgamated with existing AC line to boost up the mitigation of system deviations. Investigation reveals the dominance of GWO based PIDD controller with PEVs integration and AC-DC links in mitigating the system deviations effectively.

This retrofitting (electric conversion) project aims to modify the present structure and mechanism of Autorickshaw to make it suitable for its electrification, rather than designing a complete new E-rickshaw. This paper discusses study on feasibility check of project, selection of design parameters, validation of selected design parameters through MATLAB simulations and selection of most important devices for retrofitting i.e. traction motor and battery. Inspiration for the project is that thousands of auto rickshaws are been scrapped each year in Mumbai itself because of malfunctioning IC engine, which is a huge loss for rickshaw owners if scrapping is done before end of lifespan viz. 15 years. The old scrapped chassis and body of CNG auto rickshaw was reused to support the tagline “generating best from waste”. The BLDC motor has replaced the heart of auto rickshaw, IC engine, and the electricity of storage battery replaces the fuel and a controller is used for proper functioning and control of auto rickshaw. All this system was tried to be simulated, wherever and whenever possible by using MATLAB, and load test on motor.

This paper presents a single-phase 5-level inverter based on switched capacitor principle. The proposed topology is capable of boosting the input voltage two times. Apart from this, a suitable PWM strategy is also designed to produce a low frequency square-wave common mode voltage (CMV). This allows the leakage current to be considerably small for a transformerless implementation of the proposed topology. The proposed inverter uses only 9 controlled switches which can be realized using MOSFET or IGBT. An important advantage of the proposed topology is that the number of devices are minimized considering voltage boosting and minimized leakage current performance. This allows the proposed inverter to be used as a Transformerless inverter in case of solar PV applications. A simulation model is developed in PLECS software tojustify the various claims. An experimental set-up is underway.

A novel three phase induction motor drive for domestic ceiling fan application is proposed in this paper with improved dc-bus utilization. The proposed system is fed from a 50Hz single phase ac power source using a flyback-based power factor correction rectifier circuit, which results in 100Hz voltage ripple in the dc-link. The voltage ripple is considerable (nearly 10%) as a low value of capacitor is used to avoid high system cost. By using special carrier based space vector modulation (SVM) strategy the motor performance can be made immune to this voltage ripple but it limits the dc-bus utilization considerably. In this paper this problem is addressed by introducing an appropriate phase difference between the reference vector of the SVM and the dc-link voltage ripple. This phase difference is calculated by aligning the peaks of the modulation signal and the dc-link voltage ripple. It is shown that by doing so the dc-bus utilization can be increased. In the proposed case the dc-bus utilization is achieved to be 61% whereas any existing PWM strategy with ripple free dc-link voltage cannot have more than 57.7% dcbus utilization. Simulation studies are carried out in PLECS to support the theoretical claims. The experimental validation would be included in the final paper.

The high growth in electrical power demand, the inception of distributed generation, and the interconnection of grid networks contributed to an increase in system fault current. At places in the world, it reached an extent where the protection from this detrimental short circuit current became highly challenging. The circuit breaker’s available capacities and interruption capacity requirements have no margins. Researchers across the world are following the development of enabling technology in terms of Fault Current Limiter(FCL). Saturated Core Fault Current Limiter (SCFCL) is the most commercially viable, cost-effective, reliable, and scalable FCL technology option that can enhance the service life of protective gears in the power networks. In this paper, the two single-core configurations of SCFCL viz. Double AC Winding Model(DWM) and Single AC Winding Model(SWM), have been experimentally explored to investigate and contrast their conduct. Though the peak short circuit current is observed to be clipped significantly by SWM, the voltage drop across the device under normal conditions for designated bias has been noted to be substantially high. The bias design requirement in the case of SWM as a current limiter is critical and subjected under the compulsive constraint of insertion voltage drop in the development of FCL.

The detection of islanding events in a microgrid is a problematic issue. In this paper, four angle variations of superimposed sequence components are derived, and a new technique is proposed using the highest aggregate votes. Space vector transform is applied to decompose positive sequences and negative sequences from power signals. From the pre-state and post-state information, mathematical relationships of superimposed components are generated, and angle variation in between the superimposed component and pre-event component of each sequence is computed. This technique identifies the islanding state, even under perfectly power match conditions without the threshold setting, and hence overcomes the non-detection zone (NDZ) problem. Also, the non-islanding states such as the variable fault resistance, single-pole tripping, recloser operation, non-linear loads, and reconnection of the DEU are addressed. The proposed technique is verified using the thirteen bus microgrid simulation model in a real-time digital environment. The proposed technique is found to be fast and accurate on the change in source capacity, location, and type of DEU.

Security is a major thing to focus on during this modern era as it is very important to secure your surroundings for the well being of oneself and his family, But there are many drawbacks of using conventional security surveillance cameras as they have to be set in a particular angle for good visual and they do not cover a large area, conventional security cameras can only be used from a particular device and cannot alert the user during an unforeseen circumstance. Hence we require a much more efficient device for better security a web controlled surveillance robot is much more practical device to be used compared to conventional security surveillance, this system needs a single camera to perform its operation and the user can monitor a wide range of area, any device with a wireless connection to the internet can be used to operate this device. This robot can move to any location within the range of the network and can be accessed globally from anywhere and as it uses only one camera to secure a large area it is also cost-efficient.

The problem posed by total blackout experienced in some parts of the globe due to power system (PS) voltage instability has been traced to continuous increase in power demand. Thus, it becomes imperative to assess voltage stability in a power grid. In this paper, a method which depends on the network characteristics of a power system is investigated. This method makes use of the admittance matrix between load to load nodes in an interconnected power system. Eigenvalue decomposition method is applied on the submatrix of the admittance matrix partitioned into generator and load nodes. A comparison of the suggested method with a load flow based voltage collapse proximity index (VCPI) is also carried out. The effectiveness of methods considered is tested on both the IEEE 30-bus and the Southern Indian 10-bus power networks. Results obtained shows that, the proposed method could assist and serve as a great tool in the investigation of voltage stability in a system as it decreases computational burdens.
