Integration of DGs into the electrical network has risen significantly in the past decade and gridconnected PV systems (GCPVS) being the most popular, due to its environmental sustainability and economic efficiency. However, the connection of the renewable energy sources poses many issues related to Islanding condition. Detection of islanding condition in the DG system is a major issue that needs to be addressed. This work proposes a simple yet accurate islanding detection method (IDM) for the GCPVS by injecting a known deviation in step-size in the conventional maximum power point tracking (MPPT) algorithm. Due to this injection of disturbance, the absolute deviation of the output voltage may exceed the pre-set limit. This shifts the operating point of the system from its maximum power point which results to a drastic active power output reduction and subsequently a significant dip in the voltage in the islanded mode. Also, the DG is restored back into operating at maximum power condition after islanding classification. This makes the IDM suitable for microgrids where critical loads are catered. An intentional delay of few cycles has also been provided to overcome false-tripping in non-islanding scenarios. The presented scheme is therefore fast, accurate, does not compromise with the power quality, simple and inexpensive.

This work represents a novel Hebbian least mean square (H-LMS) technique for a proposed cascaded multilevel inverter-based SAPF. The suggested control technique is applied with the self-learning principle. Active and reactive weights updating is implemented along with DC and AC PI controller output to generate reference compensating current. This reference compensating current is used to create switching pulse signals for the MLI of the SAPF. The behavior of the suggested SAPF is analyzed through MATLAB/Simulink model. The simulation results proved that this SAPF is operating satisfactorily in both balanced and unbalanced nonlinear load conditions.

Wireless power transfer (WPT) based on magnetic resonance is the technology that might isolate humans from wires. In practical terms, the WPT utilizes the same fundamental principle researched for at least half a century under inductive power transfer. In recent years, WPT technology has undergone tremendous development, with a grid-to-load efficiency greater than 90% and the transmission distance rises from a few millimeters to several hundred millimeters at kilowatt power levels. The advancements make the WPT particularly desirable for static and dynamic electric vehicle (EV) charging applications. This work designs and analyzes multiple circular coil geometries appropriate to EV wireless charging for the WPT application. Using ANSYS Maxwell software to simulate, construct and evaluate the performance of various coil assemblies, including coupling coefficient (k), Mutual inductance (M), self-inductance (L), and magnetic flux density (B) for air gap distance of 50mm to 200 mm. The coil dimensions have been the same for all coils, and the air gap length and the copper wire specifications are uniform for equality. Using the proposed multiple coil-based WPT in EVs may easily overcome charging time, range, and cost challenges.

In the case of DC systems, there is a need to obtain different regulated output voltage levels from variable input voltage. To achieve this, flyback converter can be used in single input multi-output topology with closed loop configuration. In this connection, this paper presents an overview of the conceptual understanding behind the working principle of flyback converter and the design of multi-output flyback converter. To produce regulated multi-output voltages, a model of multi-output flyback converter is developed using Matlab/Simulink platform. In addition, the comparison of the flyback converter with other isolated DC-DC converters such as forward and push-pull converters is discussed to present the case of flyback converters and its superiority over other types of converters. The working of the designed flyback converter is verified through a laboratory prototype.

Penetration of photovoltaic (PV) sources is increasing in the distribution network (DN) which poses a concern of voltage rise due to a higher R/X ratio of DN. To tackle this, PVinverters connected to DN should take part in ancillary services. The objective of this work is to compensate the voltage rise using reactive power control. As many PV inverters need to contribute in reactive power control, the cooperative control mechanism is required. For the effective and reliable cooperative control, the communication among the various PV units is required which lead to increased cost and increased control complexity. Therefore, in this work, machine learning based i.e., neural network (NN)- based cooperative control strategy is established for the voltage regulation through reactive power control of PV inverters. The proposed method does not need costly communication infrastructure, needs only local information and it is still accurate. Moreover, this approach does not need droop control which has serious drawbacks. Through the simulations results, it is established that proposed method is highly effective for voltage regulation at various buses in DN.

Electric machines and drives are being utilized extensively in the transportation sector. Moreover, Due to resource scarcity and environmental costs, the cost of power generation has been increasing over the past few decades. Electric motors use a significant portion of the electric energy used in industry, and conventional motors are designed for costeffectiveness and longevity, not energy efficiency. Therefore, the design and development of motors with increased energy efficiency are gaining worldwide attention. These new motors can provide the same output power with compact size and reduced losses. They are designed with rare/ expensive materials, higher copper in the windings, optimized air gap, and reduced fan losses. The energy-efficient motor drives will likely remain limited to specialized applications where high efficiency and reliability are demanded. Usually, in these applications, motor drives are supplied from onboard batteries, like in electric/hybrid vehicles, ship propulsion, electric air-crafts, and so on. The research has been ongoing for the last decades to investigate and analyze various issues concerning the design, development, and use of energy-efficient machines as a replacement to the conventional three-phase machine. This paper, therefore, classifies the specialized motors based on their energy efficiency as per International Electrotechnical Commission (IEC) standards. The advantages and disadvantages of machines with different flux orientations are highlighted. A comparative analysis is also presented for available energy-efficient motors, including Permanent Magnet Synchronous Motors (IPM and SPM type), BLDC motor, Switched Reluctance motor, and Synchronous Reluctance motor. The design and simulations are carried out using Ansys Maxwell software.

Offshore wind turbines are used now-a-days to tap and convert the wind speed to electrical energy. Recent developments include installation of wind turbines in offshore seas. Monopiles, Tripods and 3- or 4-legged jacket platforms are largely used for mounting the turbine. This paper deals with the experimental analysis of an offshore wind turbine mounted over a fixed jacket platform. A 4-legged platform is currently used for the present study. Finite element methods are used for the numerical analysis of the Jacket. Code to code comparison of the results is studied to finalize the structure. A scaled down model of a steel jacket is fabricated. A scaled down model of a wind turbine is mounted on top of the jacket. The jacket and the turbine act as an integral unit. Any force or momentum acting on the turbine is transferred to the jacket and vice versa. The whole setup is installed in a wave basin capable of generating regular and random waves. The wave basin is of the size 30m length by 30m width with a water depth of 3.0m. Flap type wave generator is located at one end for wave generation and absorbers are installed on the side ends for absorbing the waves to prevent the reflection. The forces and moments acting on the structure under various loading conditions are reported. The results include the variation of the forces acting at the base of the jacket support structure with respect to the variation in different wave parameters.

Electric vehicles reduce the on-board emission of pollutants but fail in resource consumption since grid-charged batteries rely on fossil fuel consumption. Vehicles based on renewable sources further eliminate this issue delivering completely pollution-free traction. This paper evaluates an erickshaw power train fed by PV and DC battery hybrid through a dual input triple output converter topology and investigates the performance of such vehicle through simulation. A multiinput multi-output converter reduces component count and extra losses while improving space utilization and packaging. Hardware implementation is done to analyze the proposed topology. This converter will extensively improve power train efficiency while reducing losses.

The buck converter is a first and prominent member of dc-dc converters. It is commonly used for transforming electrical power at fixed voltage level to reduced voltage level.it is used in low power sector such as domestic application as well as high power like commercial, industrial application. A buck converter is implementaed by the combination of filter inductor, capacitor, free-wheeling diode, snubber and power electronics switches. But thesepower electronic switches suffer from hard-switching. As a consiquence, it introduce switching loss and causes reduction in efficency. With rapid development in semiconductor devices and significant utility in various applications, the demand of this converter is gaining momentum. But due to hard-switching of this devices, the aspect of better efficiency is a primary goal for power engineers. So the soft-switching, which is an alternative solution for the devices in these converters, need to be critically investigated. As far as the soft-switching of various dc-dc converters is concerned, the papers relevant to buck converter are lacking in literature. The addition of more than one or two switches in most cases makes the topology complex for the soft-switching operation due to which academicians and researchers lack interest in further investigation of these types topologies. Sometimes the addition of coupling inductor for isolation adds space and weight to these topologies. A modified soft-switching topology of buck converter has been proposed in this research work. It is non-isolated type and facilitates the soft-switching of the device. In order to enable soft-switching for the devices, the components of this converter are designed. The simulation is implemented with the help of MATLAB/Simulink for proposed circuit to justify the performance.

This study shows how Meta-heuristic optimization programming may be implemented to solve constrained optimal control problems. With a single-link rigid manipulator (SLM) model as an example, the proposed Crow search algorithm (CSA) is contrasted with the differential evolution algorithm (DE), whale optimization algorithm (WOA), and particle swarm optimization (PSO) in terms of performance index, which has demonstrated the notable outcomes on another algorithm.

With a single-link rigid manipulator (SLM) model as an example, the proposed Crow search algorithm (CSA) is contrasted with the differential evolution algorithm (DE), whale optimization algorithm (WOA), and particle swarm optimization (PSO) in terms of performance index, which has demonstrated the notable outcomes on another algorithm.","PeriodicalId":250652,"journal":{"name":"2023 International Conference on Power Electronics and Energy (ICPEE)","volume":"80 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114135261","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}
