The traditional Power Grid has been designed in a hierarchical fashion, with energy pushed from the large scale production factories towards the end users. With the increasing availability of micro and medium scale generating facilities, the situation is changing. Many end users can now produce energy and share it over the Power Grid. Of course, end users need incentives to do so and want to ac...

Digital technologies offer multiple opportunities for firms, but they also involve many challenges. Incumbent firms especially need to pursue digitalization in their businesses and create digital innovations in order to stay competitive in the market. For this purpose, an increased number of incumbent firms have been collaborating with start-ups with the aim of identifying and developing new bu...

The risk analysis of critical infrastructures such as the electric power supply or telecommunications is complicated by the fact that such infrastructures are mutually dependent. We propose a modular approach to themodelling and analysis of risk scenarioswith dependencies. Our approachmay be used to deduce the risk level of an overall system fromprevious risk analyses of its constituent systems...

The article considers the need to ensure reliable power supply high-tech enterprises, taking into account two location options: near city or lines, and in a territory remote from it. problem of using only one source for such enterprises is connected current instability frequency voltage changes, as well planned unscheduled outages transmission line network. A variant an automated system propose...

In today complex worldwide supply chains, intermediary organizations like Contract manufacturers and GPOs are mostly used. Well-known OEMs delegate their purchasing and procuring to these intermediaries. Because of their positive influence on supply chain efficiency, it is very important to investigate the role of intermediaries in today competitive supply chains. One important question arising...

in this paper, a low voltage and low power (lv/lp) operational transconductance amplifier (ota) using fgmos (floating-gate mos) transistor is proposed. the relative tuning range of 50 is achieved in this ota while only consumes 40 µw with 1.0 v supply voltage in tsmc 0.18 µm cmos technology. the simulation results of the proposed ota show an open loop gain of 30.2 db and a unity gain frequency ...

This research deals with the Non-Isolated Bidirectional Dc-Dc Converter (NBDC) control unit development for a smart power supply system using personal residential Photovoltaic-Power Conditioning Subsystem (PV-PCS), the results of circuits evaluation, and isolated PV-PCS operation connected battery storage (Electric vehicle storage etc.). The smart power supply system using the existing resident...
