Power data management on the Internet space: Green ICT projects in Japan

Abstract

After the M9.0 earthquake in 2011, Japan has faced severe electric shortage. The tsunami caused by the earthquake destroyed many power plans along the coast lines, and still, sufficient power is not provided even in 2012.Electricity (i.e., power data) management using information and communication technology (ICT) is getting more and more popular these days. Many projects (not only by academia but also by vendors and service providers) have been established to control such electricity using the Internet technology.This paper reports the work of "66kV power data management on the Internet space", which we have built at five campuses of the University of Tokyo.

Virtual Power Plant Performance

“…3. Since this standard is premised on Web service communication using HTTP (S), it seems that a system with excellent interoperability can be constructed for various customers [21,22]. However, it is important to note that because HTTP (S) over TCP/IP is used, Internet data transmission time may take several seconds in some cases, and the data transmission delay is probabilistically distributed.…”

An Interoperable Building Energy Management System With IEEE1888 Open Protocol for Peak-Load Shaving

“…Open platform is a key feature for the new-era BEMS. Typically, the architecture of BEMS is comprised of three main components including control device, data storage and application [11]- [13]. The control devices, in this regard, are smart meter for load power measurement and BESS; these devices are available from various vendors.…”

“…The control devices, in this regard, are smart meter for load power measurement and BESS; these devices are available from various vendors. Most vendors usually rely on the data exchange protocols from the federation of the existing access or field networks, e.g., BACnet Another open-platform BEMS is conducted in [12], [13] with the adoption of IEEE1888 open protocol or Ubiquitous Green Community Control Network Protocol. In comparison with other schemes, the exceptional features of this scheme are: 1) Common interface for gateways, data storages and applications is provided, and 2) Determination of data structure with Facility Information Access Protocol (FIAP).…”

Scalability analysis on the smart grid fast automated demand response aggregation Web services for widely distributed building facilities

“…IEEE 1888 is a framework recently developed with focus on Internet equipment monitoring, and standardized by IEEE/ISO. In so doing, web services based on HTTP(S) are used, which promises development of highly interoperable systems for various customers . It should be noted, however, that because of using HTTP(S) over TCP/IP, WAN data transmission takes several seconds, and transmission time is probabilistically distributed.…”
