COUPLED FIELD ANALYSIS OF PIEZOELECTRIC CANTILEVER BEAMijiert bestjournal
Electromechanical modelling efforts in the research field of vibration-based energy harvesting have been mostly focused on forms of vibrational in put as in the typical case of harmonic excitation at resonance. However,ambient vibration al energy often has broader frequency content than a single harmonic. Piezoelectric energ y harvesting is a promising technology for extracting the power from environmental vibrations. It generates the electrical power of few orders of amplitudes which is sufficient to drive s everal autonomous electrical devices. Such vibration-based energy harvester generates the most energy when the generator is excited at its resonance frequency. Simplest model to be start ed is of rectangular Aluminium cantilever beam with unimorph piezoelectric patch which is per fectly bonded to the substrate plate at the end. The resulting relative motion between the piez oelectric patch and the base produces stress on piezoelectric material,which is converte d into electrical power by virtue of direct piezoelectric effect. The ability of piezoelectric material of different thickness to generate voltage at different frequency is explained in this paper. Its capability to work over a range of frequency is predicted by use of ANSYS software. Th e solid model is design and analyzed using finite element software.

Misalignments are one of the most unfavorable aspects of the capacitive power transfer (CPT) system, which is inevitable in most of the applications. Misalignments affect the overall resonances in the circuit and decrease the power transfer capability and efficiency. In this paper, an automated electro-mechanical transmitter positioning system is proposed for capacitive wireless charging to withstand both axial and rotational misalignments. The system can align the transmitter based on an adaptive algorithm, with respect to the position of the receiver to mitigate the misalignments. The overall system is designed using SolidWorks and the algorithm is verified using Processing. Then, a hardware prototype is constructed in the laboratory. The accuracy of the proposed system is calculated and compared with the simulation results. The system can achieve an accuracy of 99.5%, in case of axial misalignment and an average accuracy of 98.6%, in case of both axial and rotational misalignments, which validate the simulation results.

A robust state of charge estimation for multiple models of lead acid battery ...journalBEEI
An accurate estimation technique of the state of charge (SOC) of batteries is an essential task of the battery management system. The adaptive Kalman filter (AEKF) has been used as an obsever to investigate the SOC estimation effectiveness. Therefore, The SOC is a reflexion of the chemistry of the cell which it is the key parameter for the battery management system. It is very complex to monitor the SOC and control the internal states of the cell. Three battery models are proposed and their state space models have been established, their parameters were identified by applying the least square method. However, the SOC estimation accuracy of the battery depends on the model and the efficiency of the algorithm. In this paper, AEKF technique is presented to estimate the SOC of Lead acid battery. The experimental data is used to identify the parameters of the three models and used to build different open circuit voltage–state of charge (OCV-SOC) functions relationship. The results shows that the SOC estimation based-model which has been built by hight order RC model can effectively limit the error, hence guaranty the accuracy and robustness.

Energy management strategy for photovoltaic powered hybrid energy storage sys...IJECEIAES
Nowadays, electric vehicles (EVs) using additional energy sources frequently deliver a safe ride without concern about the distance. The energy sources including a battery, an ultra-capacitor (UC), and a photovoltaic (PV) are considered in this research for driving the EV. Vehicles that only use battery-oriented technologies experience problems with charging and quick battery discharge. EVs are used with an ultracapacitor to decrease the quick discharge effects and increase the lifetime of the battery. Furthermore, bidirectional DC-DC converters are a type of power electronics device used to verify the smooth transfer of generated power from energy sources to the motor throughout various stages of the driving cycle. Therefore, this study proposes a perturb and observe (P&O) energy management control technique based on tuna swarm optimization (TSO). The suggested TSOP&O completely uses UC while regulating the battery because it lowers dynamic battery charging and discharging currents. Due to the aforementioned aspect, the suggested TSO-P&O increases battery life and demonstrates a very dependable, long range power source for an electric car. The TSO-P&O technique achieves the EVs by obtaining the maximum speed of 91.93 km/hr. with a quicker settling time of 4,930 ms when compared with the existing zero-fuel zero-emission (ZFZE) method.
Grid reactive voltage regulation and cost optimization for electric vehicle p...nooriasukmaningtyas
Expecting large electric vehicle (EV) usage in the future due to environmental issues, state subsidies, and incentives, the impact of EV charging on the power grid is required to be closely analyzed and studied for power quality, stability, and planning of infrastructure. When a large number of energy storage batteries are connected to the grid as a capacitive load the power factor of the power grid is inevitably reduced, causing power losses and voltage instability. In this work large-scale 18K EV charging model is implemented on IEEE 33 network. Optimization methods are described to search for the location of nodes that are affected most due to EV charging in terms of power losses and voltage instability of the network. Followed by optimized reactive power injection magnitude and time duration of reactive power at the identified nodes. It is shown that power losses are reduced and voltage stability is improved in the grid, which also complements the reduction in EV charging cost. The result will be useful for EV charging stations infrastructure planning, grid stabilization, and reducing EV charging costs.

By this training I have learnt So much about Electric Vehicles, advantages, disadvantages, and its Components. Also, I have learnt more about MATLAB, like how to design battery circuit, how to give required amount of current to the battery circuit and how to Identify the resultant Voltage etc. Modeling and simulation of electric vehicle’s battery is done on MATLAB/Simulink. Designed a battery circuit with 9 batteries with a voltage of 3.7V each and we have noticed that state of charge is decreases with respective to the Time. This model can be used to estimate how long the battery can be used in electric vehicles. From the plot of State of Charge is observed that after the vehicle has started running, after some time the graph has decreased in terms of charge stored in the battery. Further from the engine speed and Motor Speed, shows smooth functioning of vehicle without any distortions. This means the graph of SOC with respective to the time shown above decreases with increase in acceleration of the vehicle. Here the current is constant throughout the process because of we have connected the circuit in series, so the voltage and SOC decrease with increase in acceleration of Vehicle.

This study presents a probabilistic multi-objective optimization approach to obtain the optimal locations and sizes of static var compensator (SVC) and thyristor-controlled series capacitor (TCSC) in a power transmission network with large level of wind generation. In this study, the uncertainties of the wind power generation and correlated load demand are considered. The uncertainties are modeled in this work using the points estimation method (PEM). The optimization problem is solved using the multi-objective particle swarm optimization (MOPSO) algorithm to find the best position and rating of the flexible AC transmission system (FACTS) devices. The objective of the problem is to maximize the system loadability while minimizing the power losses and FACTS devices installation cost. Additionally, a technique based on fuzzy decision-making approach is employed to extract one of the Pareto optimal solutions as the best compromise one. The proposed approach is applied on the modified IEEE 30bus system. The numerical results evince the effectiveness of the proposed approach and shows the economic benefits that can be achieved when considering the FACTS controller.

The expected outcomes are to test the system through MATLAB/Simulink simulations showing improved battery state of charge and driving distance through regenerative braking while maintaining braking quality, and then apply the system to hardware. The goal is to develop a more efficient electric vehicle motor driver controller combining various strategies.
ELECTRIC AND SOLAR VEHICLE-DESIGN AND DEVELOPMENT.pptxsrinivasarao8004
By this training I have learnt So much about Electric Vehicles, advantages, disadvantages, and its Components. Also, I have learnt more about MATLAB, like how to design battery circuit, how to give required amount of current to the battery circuit and how to Identify the resultant Voltage etc. Modeling and simulation of electric vehicle’s battery is done on MATLAB/Simulink. Designed a battery circuit with 9 batteries with a voltage of 3.7V each and we have noticed that state of charge is decreases with respective to the Time. This model can be used to estimate how long the battery can be used in electric vehicles. From the plot of State of Charge is observed that after the vehicle has started running, after some time the graph has decreased in terms of charge stored in the battery. Further from the engine speed and Motor Speed, shows smooth functioning of vehicle without any distortions. This means the graph of SOC with respective to the time shown above decreases with increase in acceleration of the vehicle. Here the current is constant throughout the process because of we have connected the circuit in series, so the voltage and SOC decrease with increase in acceleration of Vehicle.
Power loss reduction, improvement of voltage profile, system reliability and system security are the important objectives that motivated researchers to use custom power devices/FACTS devices in power systems. The existing power quality problems such as power losses, voltage instability, voltage profile problem, load ability issues, energy losses, reliability problems etc. are caused due to continuous load growth and outage of components. The significant qualities of custom power devices /FACTS devices such as power loss reduction, improvement of voltage profile, system reliability and system security have motivated researchers in this area and to implement these devices in power system. The optimal placement and sizing of these devices are determined based on economical viability, required quality, reliability and availability. In published literatures, different algorithms are implemented for optimal placement of these devices based on different conditions. In this paper, the published literatures on this field are comprehensively reviewed and elaborate comparison of various algorithms is compared. The inference of this extensive comparative analysis is presented. In this research, Meta heuristic methods and sensitive index methods are used for determining the optimal location and sizing of custom power devices/FACTS devices. The combination of these two methods are also implemented and presented.

A probabilistic multi-objective approach for FACTS devices allocation with di...IJECEIAES
This study presents a probabilistic multi-objective optimization approach to obtain the optimal locations and sizes of static var compensator (SVC) and thyristor-controlled series capacitor (TCSC) in a power transmission network with large level of wind generation. In this study, the uncertainties of the wind power generation and correlated load demand are considered. The uncertainties are modeled in this work using the points estimation method (PEM). The optimization problem is solved using the multi-objective particle swarm optimization (MOPSO) algorithm to find the best position and rating of the flexible AC transmission system (FACTS) devices. The objective of the problem is to maximize the system loadability while minimizing the power losses and FACTS devices installation cost. Additionally, a technique based on fuzzy decision-making approach is employed to extract one of the Pareto optimal solutions as the best compromise one. The proposed approach is applied on the modified IEEE 30bus system. The numerical results evince the effectiveness of the proposed approach and shows the economic benefits that can be achieved when considering the FACTS controller.
An electric circuit model for a lithium-ion battery cell based on automotive ...IJECEIAES
This document presents an electric circuit model for a lithium-ion battery cell based on measurements from automotive drive cycles. The model uses a second-order Thevenin circuit with parameters estimated from voltage and current measurements taken during various driving cycles. Two algorithms, Trust-Region-Reflective and Levenberg-Marquardt, were tested and Levenberg-Marquardt performed better with fewer iterations. The model was validated against measurements using mean squared error and showed good performance for urban and suburban driving cycles.

This paper presents a fuzzy logic controller (FLC) based energy management strategy (EMS), combined with power filtering for a pure electric vehicle. The electrical power supply is provided by a hybrid energy storage system (HESS), including Li-Ion battery and supercapacitors (SCs), adopting a fully active parallel topology. The vehicle model was organized and constructed using the energetic macroscopic representation (EMR). The main objective of this work is to ensure an efficient power distribution in the proposed dual source, in order to reduce the battery degradation. To evaluate the impact of the developed design and the efficiency of the developed EMS, the proposed FLC strategy is compared to a classical EMS using SCs-filtering strategy and architecture based on battery storage model. To validate the proposed topology, simulation results are provided for the new European driving cycle (NEDC) using MATLAB/Simulink environment.
