In this paper, we design an architecture of Energy Management Systems (EMS) for resilient operation of microgrids and describe autonomous mechanisms that dynamically enable 1) enhancement for scalability, 2) system modification and upgrade, and 3) failure detection and recovery. Designing the resilient architecture and achieving autonomous mechanisms are of critical importance for a system operator...
Power management in electrical vehicles has become significantly a challenging task due to the growing number of sub-systems, components and energy storage systems development. Moreover, efficient modelling, simulation, evaluation and optimization of power consumption is further complicated due to the asynchronous nature of power supply requests from those sources. This paper describes a methodology...
This paper presents an experimental investigation in reusing vehicle traction lithium ion batteries for a second life application as a stationary energy storage system. A single family household demonstrated solar storage and demand side management, integrating a PV array, a grid interface and battery energy storage. The stationary battery pack, composed of retired vehicle traction batteries, serves...
The emergence of More Electric Aircraft needs to adapt their electrical architecture and their level of power generation and storage. This paper deals with the optimal sizing of battery and supercapacitor systems to match their energetic performances with the aircraft requirements. In this application, the global weight is minimized by acting on variables which are the cut-off frequency of the filter...
Today's vehicles are much more than a simple transportation device. Additional functionality such as navigation, automatic parking, and distance control has fundamentally increased the vehicles technological complexity. All these new functionalities are supported by outdated energy, and information and communications technology (ICT) systems, based on a multitude of independent and complex systems...
With the increasing ubiquity of mobile devices with computational capabilities comparable to many personal computers, while at the same time, wireless connectivity is almost available everywhere, researchers started to explore how to make use of that huge amount of potential aggregated computing resources. However, mobile devices still suffer short battery life, especially with their newly large screens...
The paper presents an agent-based scheduling and energy management system for a smart distribution feeder which is installed on a test site and includes an electric car sharing fleet. Distributed Energy storage systems provide flexibility in the operation of the test site, where the integration of multiple power sources including Renewable Energy Sources and Distributed Generators is implemented....
This paper presents the Practical Control Structure (PCS) of a heavy duty hybrid vehicle. This PCS is based on both the Energetic Macroscopic Representation (EMR) and on the Maximal Control Structure (MCS). The power sources and energy sources of this vehicle are a fuel cell system, a supercapacitors system and lead acid batteries.
The role of an existing systems architecture (SA) in requirements engineering (RE) is recognised as important, but under-researched. A recent exploratory study of ours investigated this issue in a laboratory setting involving student participants. While the initial findings are promising, much work still remains to solidify the results. Therefore, we conducted a replication of the study, and its significant...
Wireless Sensor Networks (WSN) has the potential to enrich society with some benefits, better engineering, productivity, and improved security. The main goal of energy management architecture applied in networks is to be able to allow an efficient way to enhance sensor node energy autonomy. Nowadays, there are many open issues in WSN. One of them is the energy consumption management. The sensor node...
This paper presents different works which are actually developed in the field of fuel-cell hybrid systems in different public laboratories in France. These works are presented in three sections corresponding to: 1. hybrid fuel cell/battery or supercapacitor power sources; 2. fuel-cell multi-stack power sources; 3. fuel cell in hybrid power systems for distributed generation. The presented works combine...
This paper describes energy management architecture for multimedia applications in battery powered devices to dynamically control the energy consumption of the device with an effort to increase the battery life. The architecture is divided into two parts, a notification manager and a controller. The notification manager is a generic block and is implemented as part of the system software. It consists...
