Smart grid technologies will equip the electrical grid of the future with two-way information flow between grid entities and consumers. This bidirectional information flow facilitates improved grid monitoring, control automation, energy efficiency, and sustainability. Several smart grid networking architectures have been proposed recently. However, the majority of these are restricted to subdomains...
This paper presents a new hardware design for a surveillance and controling system of a medium voltage withdrawable cell. The proposed design is based on a development board- Wilke Technology, at it is core being the Tiny Tiger 2 Multitasking Computer microcontroller with memory capacities of 2 MByte or 4 MByte FLASH for program and data, plus 1 MByte SRAM with Backup Input. In this paper I made a...
Smart grid technology is the future of electricity ordered by computers. This article presents the characteristics of the new technological developments in this area and reveals the fractal nature of this architecture, leading to a holonic structure which presents smart grid as a system bottom-up organized from autonomous entities that are recursively clustered at various aggregation layers. Taking...
This paper highlights the U.S. Department of Energy's Smart Grid R&D projects on dynamic optimization of distribution grid operations through integration of advanced sensing, communication, and control technologies. The progress and planned activities of the following programs are discussed: Renewable and Distributed Systems Integration demonstrations, microgrid developments, the Smart Grid Regional...
This paper has presented the analysis of smart grids' power and frequency control. The spreading of the continuously increasing integration of the intelligent energy distribution networks is unavoidable. The regulatory options must be tested to the safe and long-term reliable operation. In the paper the model used for simulating the smart grid is introduced, and it is also shown, how to apply for...
Synchronized measurements became recently an affordable tool ready to be implemented not only at transmission system level but also at distribution level, mostly in conjunction with the applicability of the smart grid approach. As a preliminary step of introducing PMUs on a larger scale, extensive measurements campaigns, primarily dedicated to power quality purposes, were conducted within medium and...
