Micro-grid systems are based on distributed energy resources (DERs) for example wind, solar etc., energy storage devices and scattered loads that can perform islanded as well as grid-connected operation. The concept of micro-grid has brought a paradigm shift from large scale centralized power generation to Distributed Generation (DG). It has reduced the dependence on main electricity grid and enables...
In this paper, we propose Auto-vGPU, a framework of automated resource sharing for virtualized GPU with self-configuration, to reduce manual intervention in system management while ensuring Service Level Agreement (SLA) targets. Auto-vGPU automatically collects the measurements of system metrics and learns a linear model for each application with dimension reduction. In order to fulfill the automated...
Disaster can affects a nation from functioning normally, and it can impact human, material, economic or environment. Disaster management is the concept being applied during disaster in organizing and managing resources and responsibilities of all relevant agencies in the event of disaster. Today, disaster management critically relies on information to ensure all agencies responsible can disseminate...
The justification of choice and reliability of primary converters (sensors) for use in emerging test-and-measurement and control systems for production equipment (direct heating of liquid reagents blocks) has been accomplished. A review of suitable primary converters available in the market has been provided, as well as comparison of the technical characteristics, taking into account the application...
This article is considered the features of monitoring procedure of functioning of integrated chips (IC) used in the modern radio-electronic equipment. The analysis of features of assessment dynamic and the IC static parameters is made. Control devices for measurement of their measurement dynamic and the IC static parameters are considered.
Processing of information from the sensors and the resources available to the commander are very important for his decision-making process. Quality of information for decision-making process has a great importance. This article focuses on the description of the properties of the probabilistic model for processing of sensor signals using the probabilistic model of recognition Custom / Foreign Identification...
In this paper the reliability of a Modular Multilevel Converter for HVDC applications is incremented, by decreasing the electrical stress of the main passive component suitable to fault, that is, the capacitor cell. This effect is obtained with the injection of a suitable cell second harmonic circulating current. It's important to note how the cell current increment does not increase the semiconductor...
The problems of reliable signal transmission for condition monitoring of power equipment in the energy sector during the technical diagnostics are considered. The principles of the combined coding to ensure a high level of reliability of the systems of technical diagnostics are suggested. The technique for calculating the reliability level for the information signals is represented n this paper.
Probabilities of failure-free operation during some period of time from the beginning up to the end of control influence on the classification quality of unmanned aerial vehicles radioelectronic equipment was analyzed. Interconnection between informational control completeness, probabilities of failure-free operation and its total influence on the veracity of truth classification were investigated.
New technologies for controlling power flow in electric networks have been developed in past few years. The new technologies are simpler, more compact and lower cost than the traditional power flow controllers such as phase shifters transformers, HVDC and FACTS devices. Such characteristics make them attractive for a variety of applications in transmission, subtransmission and distribution networks...
The following topics are dealt with: hybrid and electric vehicles; subsystems and components; control; infrastructure; real world experience; policy; reliability and safety; modelling and simulation.
The Web works as a network infrastructure connecting information sources and places for presenting this information. Internet of Things is next step of evolution of interconnection of intelligent information nodes/objects. Extrapolation of these techniques to the field of process control brings Internet of Processes to live. In this case artificial intelligence and SW agents in holonic systems are...
Controlling the reaction and the product quality in a large Polyester Intermediates plant has been an intractable problem for many years. Handling difficulties and the hazardous nature of the process has made it impossible to get real time measures of the product or of the dissolved catalyst. Model Predictive Control was implemented, but failed to give reliable control. Now a simplified Process Model...
Permanent Magnet (PM) machines are increasingly being used in safety critical systems in aerospace and automotive applications. In such applications, reliability and availability are key concerns. Numerous works have been presented in literature which take into account both system reliability and availability in the event of single fault within the PM machine. This paper mainly focuses on a turn Short-Circuit...
In ICT for agriculture, there are three types of horticulture systems. The first is for collecting and analyzing temperature data in agricultural fields, such as a grape plantation. The second is used for plant factories that continuously produce vegetables, regardless of location or season, in an artificially controlled environment. The third is greenhouse horticulture for raising vegetables, fruit...
This paper concerns the overall challenge and opportunities of introducing students to problems underlying the ongoing electric energy systems evolution. It is critical to teach both breadth and depth, but the overcrowded curricula does not allow for the huge number of courses. This calls for introducing principles of modeling, analyzing and designing future electric energy systems using concepts...
The rapid increase in global energy consumption and the impact of greenhouse gas emissions has accelerated the transition towards greener energy sources. The need for distributed generation employing renewable energy sources such as wind, solar and fuel cells has gained significant momentum. Advanced power electronic systems, affordable high performance devices, and smart energy management principles...
It was carried out preliminary study of the effect of degree sample deflected mode on the parameters of the electric response using multisensor control system, based on phenomenon of mechanoelectrical transformations in dielectric structures. Deflected mode provided by the uniaxial compression of the sample in the press. It has been shown the high efficiency of the multisensor system, which allows...
Smart grids are characterized by a dynamic nature in which distributed energy resources (DER's) changes internal states and availability over time. Distributed Energy Resources (DER's) and the distributed control system will thus be required to automatically configure itself to this dynamic behavior. This paper1 addresses communication and control challenges to achieve a plug'n'play type of DER management...
During the past few years, a worldwide acceptance of IEC 61850 has been demonstrated as more and more substation devices are being integrated based on Ethernet technology. This trend represents new challenges for integrators, manufacturers, and end users. However, the field-proven benefits and lessons learned are truly valuable to managers, supervisors, and executives curious about bringing the benefits...
