Abstract. Continuous development of intelligent network applications drives the demand for deployment-ready hardware and software solutions. Such solutions are highly valued not only by distributed producers of energy but by energy consumers as well. The use of intelligent network applications enables the development and improvement of the quality of services. It also increases self-sufficiency and efficiency. This paper describes an example of such device that allows for the control of a dual active bridge (DAB) converter and enables its remote control in real time over an IP-based network. The details of both hardware and software components of proposed implementation are provided. The DAB converter gives a possibility to control and manage the energy between two DC power systems with very different voltage levels. Not only information, but also the quality of energy, the direction of power flow, and energy storage systems can be easily controlled through an IP-based network and power electronics converters. Information technology, together with intelligent control of power electronics technology, provides a flexible solution, especially for sustainable smart grids.Key words: ARM processor, DAB converter controller, networked controller, Web-based user interface, energy control.Implementation of a Web-based remote control system for qZS DAB application using low-cost ARM platform infrastructure and tuned to facilitate the integration of all involved". It became truly multidisciplinary, as it attracts research and development not only by electrical engineers, but also by entrepreneurs, economists, sociologists, politicians, lawyers, and finally, IT-specialists [12,13]. However, a smart grid is not only smart metering, but also smart controlling of the energy conversion process and power flow management (flow direction, energy storage and conditioning). The two most recent decades were dedicated to Internet communication. The next two or more decades will not be focused only on the Internet, but also on the Energy Net network, where it is the energy that will be managed, instead of information [14]. The tools necessary to implement this vision are microchips like digital signal processors (DSPs), complex programmable logic devices (CPLDs), field programmable gate arrays (FPGAs) or advanced RISC machines (ARMs) to, in real time, control transistors and thyristors switching in different types of power electronics converters. Because the technology of reduced instruction set computer (RISC) is flexible and achieved a sufficient level of maturity, the price of ARM devices became very competitive. That leverages the ARM platform as a suitable tool to handle intelligence communication and at the same time provide robust operation at a reasonable price [15]. This ARM-based solution provides the environment for real-time communication using different protocols.The paper is focused on an ARM-based solution for the control and Web-based management of a DC-DC power elec-

A method to extract unique features from measured waveforms of nonlinear loads is presented. These features can be used for the identification of loads connected to the grid. The method is based on the currents' physical components (CPC) electric power transport theory combined with the Z-transform (for implementation using digital signal processing (DSP). A set of admittance-based Z-transform functions that reflect the current physical components suggested by the CPC is constructed. The resulting transfer functions are shown to reflect the electric physical significance, and are used for electric load and machine identification through its electric characteristics. In this paper, the Z-transform analytic expressions are developed and extended along with their physical comprehension. Moreover, the strength of the theory over more traditional spectral analysis is explained. The method presented in this paper is demonstrated and analyzed using real-world measured waveforms (measured by power quality monitors).

“…For instance, Chang et al [23] in their tests used three loads: (i) a 160-hp induction motor, (ii) a 123-hp induction motor driven by variable-voltage drives, and (iii) a bank of loads supplied by a six-pulse thyristor rectifier for ac power. Fernandes et al [24] used some residential loads (lights, fan, computer and monitor), arcing, ferromagnetic devices, adjustable speed drive, and six-pulse HVDC. A collection of related works can be seen in Table 1.…”
