The forces exerted due to the transient currents in a power transformer can result in deformity of core and winding. These transient currents are the excessive current arising in the transformer at the time of short-circuit fault. This study aims in examining the axial and radial force generated in the transformer's high voltage winding and the deformations associated with it when a double line short-circuit fault occurs. The analysis has been done for a three phase 11/66 kV power transformer of 40 MVA. Finite element method is employed using COMSOL Multiphysics. The electromagnetic force study is significant in determining various design parameters of the power transformer so as to protect it from the harmful effects taking place due to the transience in currents.

This paper exhibits an attempt for controlling the frequency of an independent microgrid (MG) system by using modified bias (MB) and Internal Model Control (IMC) based PID Controller with mine blast algorithm (MBA) under extreme unfavorable scenarios. Frequency deviation occurred in the system because of mismatch between Actual Generated power and total load demand. To address this issue the IMC-based the frequency regulation and gain parameters of the Microgrid are taken into consideration for finding the limits of control parameters for MBA, which will make sure that the search points produced by MBA are robust and stable. In real-time simulation environments using the digital simulator OPAL-RT, simulation of the proposed (MBA based MB-IMC) controller-based MG model has been appropriately tested. In various real-life situations, the system performance is obtained using the MBA-MBIMC controller and system outputs are closely investigated. The performance of MBA-MBIMC Controller is compared with that of PSO-MBIMC, MBIMC and MB-LDR controllers. The result shows that, in forms of peak deviation, time of settling and a smaller no. of oscillations, the proposed MBA-MBIMC controller provides the most optimum adaptive output.

With rapid growth in the demand of electrical energy across the globe, has increased the use of renewable sources for generation of power. The renewable sources can act as standalone system but their operation is not reliable because of their intermittent nature. This causes the load frequency to deviate in addition to load deviation caused by load change. But interconnection of renewable sources with conventional sources like thermal generation reduces the load frequency deviation to a greater extent. In this work Load Frequency Control (LFC) of distributed system involving thermal, wind and solar generations has been presented. For controlling the frequency deviations by tuning of PI controllers, intelligent techniques are proposed like BFO and PSO. These optimizing techniques are very powerful techniques which are gaining popularity in industry. This paper also discusses the comparative study between BFO and PSO algorithms to determine the optimum parameter of PID controller for automatic load frequency control. A System involving a thermal plant, wind generation system and solar generation is modelled and simulated.

For DC to AC power conversion, Reduced Device Count (RDC) Multilevel Inverters (MLIs) plays a very important role in the mean of low voltage input applications. In this paper, a single phase nine level Switched Capacitor (SC) based grid connected inverter with LCL filter has been proposed and this inverter operates with single DC source maintains voltage gain as two. For PWM operation of inverter, a Unipolar Phase Disposition (UPD) pulse width modulation technique has been used. With respect to better/ higher ripple attenuation, efficiency and stability considerations are have been taken into account for the design of LCL filter. The d-axis and q-axis current controllers are used to inject active and reactive powers to the grid respectively. The proposed system has been validated using MATLAB/Simulink platform.

Modern day grid operation requires multiple interlinked applications and many automated processes at control center for monitoring and operation of grid. Information technology integrated with operational technology plays a critical role in grid operation. Computing resource requirements of these software applications varies widely and includes high processing applications, high Input/Output (I/O) sensitive applications and applications with low resource requirements. Present day grid operation control center uses various applications for load despatch schedule management, various real-time analytics & optimization applications, post despatch analysis and reporting applications etc. These applications are integrated with Operational Technology (OT) like Data acquisition system / Energy management system (SCADA/EMS), Wide Area Measurement System (WAMS) etc. This paper discusses various design considerations and implementation of converged infrastructure through virtualization technology by consolidation of servers and storages using multi-cluster approach to meet high availability requirement of the applications and achieve desired objectives of grid control center of north eastern region in India. The process involves weighing benefits of different architecture solution, grouping of application hosts, making multiple clusters with reliability and security considerations, and designing suitable infrastructure to meet all end objectives. Reliability, enhanced resource utilization, economic factors, storage and physical node selection, integration issues with OT systems and optimization of cost are the prime design considerations. Modalities adopted to minimize downtime of critical systems for grid operation during migration from the existing infrastructure and integration with OT systems of North Eastern Regional Load Despatch Center are also elaborated in this paper.

This paper is focused on the design of fractional differentiator for complex orders of $alpha+jbeta$ where $alphain[0,1]$ and $betainRe$. Furthermore, for the practical realization of these fractional differentiators of complex orders, curve fitting-based approximation using Sanathanan-Koerner iteration is proposed. The fractional differentiator results with complex orders show that the proposed approximation is effectively handled both positive and negative imaginary parts of the complex orders. Furthermore, the results on fractional-integrator, PID controller, and low pass filter with complex orders show that the proposed technique has produced better approximation for the range $omega$ in [$omega_{l},omega_{h}$]. The results also show that introducing an additional parameter has given more flexibility to obtain its robust performance.

Water demand for irrigation, livestock, rural areas and agriculture keeps on increasing by the day in India. Most Farmers are using the same conventional techniques for irrigation purposes. As we know, the cost of fuel and electricity is rising constantly and due to no grid connection in rural areas, solar photovoltaic water system pumping (SPVWPS) is the best alternative for irrigation and other purposes. SPVWPS ensures long product life and it has a very low maintenance cost. Hence, solar photovoltaic water system pumping can be a solution to fulfil the demand. The aim of this study is to design and simulate the solar photovoltaic water pumping system. Designing and simulation of an SPVWPS is being done by the software PVsyst Version 6.87. For a case study and simulation, a village called Bhagipur, near Etah district Uttar Pradesh, India (27.63° N 78.67° E) has been preferred as a location. Results show the effect of various performance parameters such as (global Irradiation, diffuse Irradiation, Temperature, etc) on the system. Paper further shows system losses over the whole year.

This paper presents flux density analysis of the Permanent Magnet Synchronous Machine in a closed-loop system. This system is developed in co-simulation with Ansys software using the FEM model of the machine. Here the vector control technique with constant mutual flux linkage control strategy is implemented. Different parameters such as electromagnetic torque, speed, stator current, flux density at different parts of the stator is analyzed in different operating conditions. However, the losses of motor highly depend on the rate of change of flux density, which is the utmost factor while designing Motor drive. The novelty of the paper implies the consideration of flux density variation in different parts of the stator core under the different test cases. However, in case of MATLAB/Simulink it's not possible to consider these losses inherently. The FEM model of the PMSM is insinuated to the practical model of the motor. Hence this analysis will be helpful for the designer to improve the drive system towards practical applications.

A grid-connected photovoltaic (PV) system using a six-switch asymmetrical 9-level inverter is presented in this paper. One of the major advantages of the proposed grid-tied PV system using the six switches 9-level inverter over other existing topologies is that the number of conducting switches is only two for obtaining any voltage level. Thus the proposed grid-tied PV system is more efficient than the other PV system. Moreover, the proposed PV system can be extended to a high-power using cascading of several 9-level modules as well as to a three-phase structure very easily. A closed-loop current control technique is developed to balance the DC-link voltage in the ratio of 1:2. An experimental prototype of the proposed 9-level inverter-based PV system is developed in the laboratory demonstrate effectiveness of the control technique and to validate the simulation results.

In this paper, a double stage seamless AOGLMS (Averaged Overdetermined Generalized LMS) control technique is used for a solar PV (Photovoltaic) based distributed generated system (DGS), in standalone mode (SM), and the grid-connected (GC) mode with multifunctional capability. This DG system has BDDC (Bidirectional DC-DC converter) with a battery, solar PV array generation, voltage source converter (VSC), and nonlinear/linear loads. The SPV battery system is capable to store the extra power of solar generation into the grid. Moreover, it has dual capability for performing both operations in GC mode and SM mode. Here, the MPPT based on P&O (Perturb and Observe) technique is used to harvest the peak power from the SPV array. In GC mode, the solar array is tied to the DC-link with a boost converter, and BDDC is used for maintaining the DC-link voltage with transferring the active power. Moreover, in GC mode, the robust control technique provides a seamless operation with eradicating the harmonics at different loading conditions. However, in the synchronization mode, the load voltage angle, and the grid voltage angle are obtained through the PLL (Phase Locked Loop).

However, in the synchronization mode, the load voltage angle, and the grid voltage angle are obtained through the PLL (Phase Locked Loop).","PeriodicalId":250203,"journal":{"name":"2020 3rd International Conference on Energy, Power and Environment: Towards Clean Energy Technologies","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122196767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
