Building Automation Networks for Smart Grids

Abstract

Smart grid, as an intelligent power generation, distribution, and control system, needs various communication systems to meet its requirements. The ability to communicate seamlessly across multiple networks and domains is an open issue which is yet to be adequately addressed in smart grid architectures. In this paper, we present a framework for end-to-end interoperability in home and building area networks within smart grids. 6LoWPAN and the compact application protocol are utilized to facilitate the use of IPv6 and Zigbee application profiles such as Zigbee smart energy for network and application layer interoperability, respectively. A differential service medium access control scheme enables end-to-end connectivity between 802.15.4 and IP networks while providing quality of service guarantees for Zigbee traffic over Wi-Fi. We also address several issues including interference mitigation, load scheduling, and security and propose solutions to them.

An Improved Backward/Forward Sweep Power Flow Method Based on a New Network Information Organization for Radial Distribution Systems

“…For a simple-intermediate or terminal bus, the branch current is obtained using equation (2). If the bus of the main line is a common bus, the current in the next branch is obtained using equation (6).…”

“…e load consumed or produced in medium-and lowvoltage distribution network at each bus can be measured by electronic meters [1] and can be transmitted through advanced metering infrastructures [2], or it can be estimated from the forecast of load demand [3]and the solar [4] or wind prevision [5]. However, knowing the loads at each network node is not sufficient to conceive network control applications, and further information is needed, such as voltage magnitude and voltage deviation of each network node; capturing that information directly requires serious investments in sensors and new communication infrastructure [6]. Avoiding those investments is possible, thanks to a tool named "load flow analysis" [7], which is able to calculate the needed network information only from the values of load consumed or injected of each node.…”

A Priority-Based CSMA/CA Mechanism to Support Deadline-Aware Scheduling in Home Automation Applications Using IEEE 802.15.4

“…As future works, the authors aim to a better evaluation of proposed approach performance, in terms of the effects of contention occurring on the tunneling medium. The use of 6LoWPAN and IEEE 802.15.4 protocols has been presented in [27], while 6LoWPAN, IPv6, and IEEE 802.15.4 protocols are also used in [32]. The authors propose a prototypical implementation of a home automation network that uses IPv6 over 6LoWPAN to control home applications.…”
