It was developed to study the behavior of lithium-ion battery key parameters. The thermal model, under Matlab/Simulink, is capable of predicting the voltage, current, State of Charge and temperature of the battery. Thereafter, the thermal behavior of the battery was studied under different operating conditions. The results of the simulation were compared with experimental measurements carried out by thermocouples and thermal camera on a test bench. Finally, the model has been validated on the NOAO electric vehicle.

The model of the system is first developed using data obtained from experiments over two aggressive driving cycles and then used to validate the model and further used as a platform to test other control strategies. The car's actual control strategy operates on high torque region of the engine to sustain battery charge and caused high fuel consumption. Based on previous researches, there are two optimal control strategies that can be implemented for a series hybrid electric vehicle system; the dynamic programming control method and the optimal torque control method. Result analysis shows that the operations of the engine are different between the two control methods; it is concentrated on high speed region for the dynamic programming control method and at the middle of the engine map for the optimal torque control method.

By exchanging more frequent information between the smart meter and Utility Provider (UP), SG will operate more efficiently with less loss. However, this frequent exchange poses a serious privacy issue which can invade individual privacy since the UP is able to collect a massive amount of smart meter-related data not necessary for billing purposes. In this paper, we propose an efficient sustainable model that uses a local energy to enhance the consumer privacy and reduce his electricity cost at the same time. Moreover, the proposed model is lightweight but also reliable to deal with the low computation capacity of the smart meter. Analytic results prove the efficiency of our model.

In addition to the technological developments that make electric vehicles more and more suitable for long-distance traffic, the legislative framework also imposes these developments, such as the announced end of thermal vehicles in France in 2040. However, it is not possible to use an electric vehicle in the same way as an internal combustion vehicle. This technology impose to take into account the aging of the battery in order to define its use.

To run such a measure, it is necessary to use specific software and hardware tools to instrumentation fuel cells. In this context, we presented the steps of designing and developing an application for the measurement of the complex impedance by electrochemical impedance spectroscopy method (EIS) using LabVIEW® software.

The new opportunities brought by the development of automated functions for vehicles leads to a restructuring of the possible services. The goal of this paper is to present first an overview of the existing solutions for goods transportations systems based on automated and/or alternative solutions and second to sketch the outline and the related issues of a possible solution based on platoon control.

As opposed to exact methods, which could give the best results of a tested problem, this meta-heuristics is based on the stochastic logic but not on theoretical mathematics demonstration (or only on certain well defined applications). According to this, the weak point of this meta-heuristics is his convergence, its termination condition. We can finds many different termination criteria in the scientific literature, yet most of them are costly in resources and unsuitable for practical problems. On the other hand, given the fact that the ACO is a stochastic approach, it seems difficult to decide whether to stop the algorithms in order to have the optimal result of the tested problems. Therefore, the thesis of this paper is to propose an approach based on the environment in order to determine the best termination criteria of the ACO, for an optimized solution.

In this paper, we present the Matlab/Similink modeling of a clean hydrogen production system which consists of water electrolyzes coupled with a PV panel system. Hydrogen is produced by the chemical process of water electrolysis. The necessary current is supplied by a photovoltaic system. Simulation of Matlab/Simulink is to provide an electrical model of the water electrolysis and the PV panel system. The obtained results are the current-voltage characteristics I-V of the hydrogen production system. This hydrogen will then be stored in a tank to be used by a PEM fuel cell to power an electric load at any time. This system is advantageous so that it allows us to have stable electrical energy during the period of darkness or poor irradiance.

Electricity production process is considered among the principal CO2 emitters since it relies heavily on non-renewable sources like coal and natural gas. However, switching to green electricity generation as hydro or wind is not yet evident because they represent intermittent sources that are highly weather-dependent and can meet now at maximum 14% of electricity generation needs. Moreover, green electricity is often more expensive than non-green ones. As governments and utilities worldwide seek to reduce carbon footprints and conserve energy, they are interested to use further wireless Internet of Things (IoT) technologies to transform traditional energy infrastructure into interconnected smart grid. Smart meters are an essential element and usually the first milestone in smart grid implementations. In this context, we propose an optimization model embedded in these IoT devices (i.e. smart meters) to intelligently schedule energy consumption from renewable & non-renewable electricity providers and an energy storage system (battery) to meet smart buildings electricity requirements. The proposed optimization model takes into consideration several constraints, namely the availability as well as the electricity price of each source. The goal of this model is to find the best proportion of using each source in order to reduce CO2 emissions but also taking into account the minimization of consumer's billing cost. Simulation results prove the efficiency of our model either with or without using carbon emissions tax to penalize using non-green energies.

Some problems related to fuel cells used in the electric vehicle field are the management of its efficiency and the lifetime of its membranes. To do this, the diagnosis using measuring the complex impedance is an important phase. It is based on the injection of a perturbation signal at the output of the PEM fuel cell, then we observe its behavior by measuring its impedance. The used measurement method is the electrochemical impedance spectroscopy (EIS) using the load modulation technique, which is implemented in an embedded measurement system based on a microcontroller. This embedded system needs a controlled oscillator using a frequency spectrum range from 10 mHz to 15 kHz. With this larger frequency bandwidth swiped for measuring the PEM fuel cell complex impedance, this oscillator is a first in the impedance spectroscopy field.

The input parameters of the model are separated into system properties, linked to physical values, and running conditions. On the 40 system properties required, a sensitivity analysis was applied in order to identify that only four membrane properties have the most influence on the stack voltage. These parameter values were identified by optimization. The prediction accuracy with the new parameter values decreased to 1.48%.

This paper attempts to improve simulation model of fuel cell system that is easy to use and at the same time have an acceptable accuracy. The simulation model is developed through Matlab/Simulink software using Energetic Macroscopic Representation method which accuracy is compared with an established model. Simulation analysis of fuel cell integration is conducted by using experimental data from a real hybrid car. There are two potential types of system that were considered for the hybrid car in term of electricity generation and power produced to move the car, a full fuel cell car or a hybrid of fuel cell and battery. Analysis reveals that the hybrid car using combination of fuel cell and battery system is more effective compared to the car using fully fuel cell system due to factors that prevents fuel cell wide utilization for the vehicle.

Since state estimation is a critical entity to monitor and control electricity production and distribution, intruders are more attracted by this entity in order to disrupt the smart grid reliability. In this context, we propose an Intrusion Detection System (IDS) architecture to detect lethal attacks with a focus on two smart grid security issues: (i) Firstly, against integrity issue with price manipulation attack, we propose a Cumulative Sum (CUSUM) algorithm that detects this attack even with granular price changes; (ii) Secondly, the availability issue with Denial of Service (DoS) attack against which we develop an efficient method to monitor and detect any misbehaving node. Performance evaluations show the robustness of the proposed IDS system compared to existing mechanisms. The achieved detection rate is above 95% and the false positive rate is below 5%.
