The exponential increase of electric energy demand, in parallel with the forthcoming exploration of Distributed Energy Resources (DER), as Renewable Energy Resources (RES), makes the future electric network more and more complex, therefore it is required the implementation of active distribution networks, with rapid control decisions counter to the passive or conventional power network. This paper tries to meet at least in part of these objectives thanks to Multi Agent System (MAS) technology. A system study case is deployed as a multi sources system with a hybrid storage in a microgrid. The control decision is ensured by agents developed under jade platform, the simulation is carried out by Matlab Simulink, thanks to MacsimJX that enables the communication between the two architecture. The results had shown that the microgrid ensures the continuity of the service under different conditions; absence of element, fault, sudden load variations and intermittent of RES.
Storage systems are a foundational component of computational, experimental, and observational science today. The ever-growing size of computation and simulation results demands huge storage capacity, which challenges the storage scalability and causes data corruption and disk failure to be commonplace in exascale storage environments. Moreover, the increasing complexity of storage hierarchy and passive storage devices make today's storage systems inefficient, which force the adoption of new storage technologies. In this position paper, we propose a Parallel, Reliable and Scalable Storage Software Infrastructure (PASSI) to support the design and prototyping of next- generation active storage environment. The goal is to meet the scaling and resilience need of extreme scale science by ensuring that storage systems are pervasively intelligent, always available, never lose or damage data and energy-efficient.
The General Motors (GM) EV1 is an electric vehicle originally powered by either a PbA or NiMh battery pack. This paper examines the possibility of alternative powertrain configurations. These alternatives include an ultracapacitor (UC) storage system, fuel cell system with UC storage, and a fuel cell system with a NiMh battery pack. The configurations were simulated using ADVISOR. Parametric tests were performed by varying the size of the energy storage systems. The study of these combinations is followed by an examination of the current art of the hybrid energy storage topologies used to combine battery and ultracapacitor storage. These topologies include passive parallel, active parallel, cascade parallel, and multi-input bidirectional converter.
Hardware Transactional Memory (HTM) designs must implement conflict detection to guarantee the correctness of transaction execution. A conflict occurs when more than one transaction access the same data and at least one of them attempts to modify the data. The corresponding conflict detection mechanism usually works at a cacheline level that fits naturally into the cache coherence protocol. Thus, the inter-transaction communication for conflict detection is usually mapped onto the coherence communication controlled by the directory-based coherence protocols. In this paper, we identify inefficiency introduced by such mappings. The net effect of such inefficiency is excessive on-chip network traffic that consumes substantial dynamic power as packets are switched over the routers and links. We present TMNOC, a HTM and Network-on- Chip (NoC) co-design to improve network energy efficiency. The on-chip network, instead of a passive communication substrate, proactively filters out transactional requests that waste energy yet having no contribution to the progress of transactions. Experiment results show that TMNOC reduces energy consumption of the on-chip network by 14.5% on average (up to 38%) across a wide range of transaction applications.
The micro superconducting magnetic energy storage system is becoming a powerful tool for application in power systems. Nowadays, devices include active shielding systems instead of passive ferromagnetic shields. This calls for sophisticated analysis and design techniques able to provide satisfactory performance in terms of stored energy efficiency, reduced stray field, and/or minimal superconductor's volume. In this paper, the features of an active shielding system using multiple parallel solenoid configurations for superconducting magnets are analyzed and the results of their corresponding stray fields are compared. Two optimization strategies are briefly presented. The results using the proposed optimization strategies for magnet systems of energy capacity of 1 MJ, 5 MJ, and 10 MJ are given, respectively.
Bi-directional inverter circuits are commonly used in many applications in power systems, such as in FACTS devices, energy storage systems and active power filters. Many power engineering students however find it difficult to understand the conducting states of the active switches (transistors, IGBTs) and the passive switches (the anti-parallel diodes connected across the active switches). It seems a mystery to them that power can flow from a lower voltage ac system to a higher voltage dc system to charge the energy storage system. This paper proposes a simple chart that intuitively explains how to determine the states (either conducting or non-conducting) of the active and passive switches of an inverter. The flowchart helps students to understand the cyclic changes in the topology of the circuit in a switching cycle. The flowchart by nature is general and can be used for any type of control methods such as sinusoidal PWM and hysteresis control. The application of the use of this chart is also discussed for a battery energy storage system.
This paper describes the system to control reactive power and harmonics flowing into a power system using a self commutated converter. Active filters and the reactive power controls which use voltage source inverters are put to practical use with many applications. A SVG (static VAr generator) has been used in order to restrain power oscillation against fluctuation of the power system. SVG has been applied in order to control the voltage of an electric train substation. Passive filters compensate for harmonics and reactive power of the power system. When parallel resonance occurs between the passive filter and reactance of the power system, harmonics of the power system spread. A self commutated converter compensates for harmonic load current and restrains parallel resonance between the system and the passive filters. Power converters are used for a power supply of superconducting coils such as SMES. Because the volume of these power supplies is more than dozens of MVA, many converters work in parallel. As a power supply for the superconducting coil, a parallel system of thyristor converters and self commutated converters has been examined. The passive filter is connected for reactive power compensation and harmonics absorption of the thyristor converter. A self commutated converter controls reactive power of all thyristor converters and the passive filter. It restrains harmonics further while damping parallel resonance of the passive filter and power system.
Symmetric ankle propulsion is the cornerstone of efficient human walking. The ankle plantar flexors provide the majority of the mechanical work for the step-to-step transition and much of this work is delivered via elastic recoil from the Achilles' tendon - making it highly efficient. Even though the plantar flexors play a central role in propulsion, body-weight support and swing initiation during walking, very few assistive devices have focused on aiding ankle plantarflexion. Our goal was to develop a portable ankle exoskeleton taking inspiration from the passive elastic mechanisms at play in the human triceps surae-Achilles' tendon complex during walking. The challenge was to use parallel springs to provide ankle joint mechanical assistance during stance phase but allow free ankle rotation during swing phase. To do this we developed a novel `smart-clutch' that can engage and disengage a parallel spring based only on ankle kinematic state. The system is purely passive - containing no motors, electronics or external power supply. This `energy-neutral' ankle exoskeleton could be used to restore symmetry and reduce metabolic energy expenditure of walking in populations with weak ankle plantar flexors (e.g. stroke, spinal cord injury, normal aging).
This study presents the multiple energy storage elements usability for ships using a passive hybrid topology. The considered hybridisation is based on a passive parallel topology connecting NiMH batteries and SuperCapacitors to a DC power distribution by a bidirectional DC/DC converter. The overall propulsion architecture is a hybrid series system where an engine-generator group is the main energy source and the multiple energy storage system (ESS) answer the intermittent power demanded by the on-board loads. First, the multiple ESS is sized using voltages, storage elements' characteristics, and typical power demand profile. Thereafter, a control scheme of this hybridisation is deduced through a cascade of current and voltage linear controllers. The energy management strategy based on the stability of the DC power distribution voltage and the inherent storage elements' characteristics is fully addressed in order to reduce weight and space on-board, fuel consumption, pollution, and optimise the global efficiency. Experimental results show that the engine-generator fulfil a constant power, meanwhile the multiple ESS stabilises the DC-link voltage with unknown power demand profile. The effectiveness of the proposed passive hybrid topology with reduced control layer complexity based on the DC-link voltage stabilisation as an energy management strategy is validated.
This paper proposes a multimode control strategy for a doubly fed induction generator-based wind-power unit, which enables operation in the islanded (autonomous) mode as well as the grid-connected mode. The configuration can be an option for electricity generation in remote communities with favorable wind conditions, but limited or unreliable connection to the grid. In the grid- connected mode, the proposed control enables the wind power unit to operate with or without battery energy storage, as desired. In case that the wind- power unit is augmented with battery energy storage, in the islanded mode, the proposed control strategy enables voltage and frequency regulation for the network, and parallel operation with constant-speed wind-power units, induction motor loads, and passive loads. The proposed control strategy employs a unified controller for all of the foregoing modes of operation and, therefore, relieves the need for switching between different controllers or reconfiguration of the hardware. The effectiveness and robustness of the proposed control strategy are demonstrated for faulted as well as normal operating conditions through simulation studies carried out on a detailed switched model of the system in the PSCAD/EMTDC software environment.
