Functional specifications AE2000

Proposed specifications for GPX AE2000 - Green Power eXchanger

INTRODUCTION

This GPX AE2000 User Interface Design is intuitively made and
provides an idea of basic functions to communicate with a user with
digital certificates.

This design does not describe the system for distributing digital certificates
for green electricity. For the design of the distribution channel please contact
the GPX representative. Scroll down or Click here for Specifications.

The protocol for the exchange according to the European Energy Certificate
System as provided by the Association of Issuing Bodies : see the Acrobat-
document dating from September 2005: "AIB EECS details" - original source:
AIB.

The GPX AE2000 User Interfaces are start-up examples for
manufacturing or further development. The next generation kWh meters
can communicate with GPX. Hence GPX can act as a user interface to
determine the energymix desired by the consumer by means of modern
smartcard technology and/or internet technology.

Design on client specification.

Suggested further development in the idea of the "home automation":

1. GPX product family comprising:
      - main unit with modular (for example clickable) extensions
      - remote communicating GPX "SmartPlug"
2. Modules for:
      - USB port
      - Clock & Timer functions
      - Thermostat sensor functions
      - Security alarm sensor functions
      - Wireless functions (GPRS/UMTS/Bluetooth/Zigbee/IEEE802.11/IEEE802.15/IEEE802.16, etc)
      - Internet by wall-outlet (for example RJ45 or RJ11 for small telephone plug - outlet aside the unit)
3. Communication (token, PLC or wireless) to functional related systems:
      - GPX product family for sub-metering
      - the wall outlet and the circuitbreaker system
      - central heating system
      - main contract-meters for electricity, gas and water
      - tv-on-demand-box
      - personal computer, desktop, laptop, palmtop, pda

The GPX Energy Manager package is for sub-metering and dedicated supply of Green Energy from Point-to-Point. The GPX EM can provide detailed insight in the dynamics of your energy consumption of house, kitchen, garden, office, etc. Your (home)organisation will benefit from monitoring the patterns of consumption of totals and detailed energy. From the patterns you can easily retrieve improvement for the efficiency on every level of use. Optimize and improve your energy processes at home, office and factory with GPX devices and monitor them straight on every PC.

One live test has been conducted on the presented GPX AE2000 prototype (mock-up unit). It saved a total of 30% on annual spendings on the use of electricity, gas and water. The project was conducted in combination with an ECO-TEAM programm of the Global Action Plan. To learn more about GAP, see item nr.7 at www.gpx.nl/swing.htm (opens on a new page).

Presented system is part of patent NL 1013568, with several international patents granted.

SPECIFICATION GPX AE2000-C Consumption Module Picture: Green Power eXchanger - Groene Energie Stopcontact

go top

The depicted GPX AE2000-C is a plug-and-play meter unit for the wall-outlet for the measurement of the consumption of certificates of specific energy production.
It comprises a digital kilowatt-hour meter combined with a register in which the digital green certificates are stored. The certificates are brought into the register by smartcard.
As a plug-and-play unit, GPX AE2000-C transforms the renewable certified energy tickets back to concrete electrical power. In this way, the circle of production and consumption of green certificates is closed. The digital certificates can be produced with an energy meter at for example the solar PV cells on the roof and can be consumed with GPX AE2000-C Consumption Module at another time and location.

The new module presently in development is the GPX AE2000-P Production Module. It will produce the certificates for solar production. The register from the Production Module will store the measured amount of energy in the internal register. The produced certificates from the register can be booked onto the smart card after the smartcard is inserted. With the both modules, a set for demonstration will be set together for the educational market.

Testing/certification

The GPX AE2000 types must comply with the standard IEC 1036 for static kWh meters - for the Dutch and European market. It can be tested at NMI including CE mark - contact: Jos G.M. van der Grinten, telephone +31 78 633 2308, fax +31 78 613 46 47 or e-mail CertinSales@NMi.nl. NMI can help to clear to what specific standards the GPX AE2000 modules will have to comply regarding kWh-metering.

Companies producing GPX are willing to meet ISO SR or ISO 26000 (to be published in 2009). Companies producing GPX modules have or are working towards certification for the Environmental Management ISO14001 standard, and understand the C2C, the Cradle to Cradle concept.

It is the chain of good things we're trying to bridge with GPX, to approach a better environment. We want to present a metrological strong solution for bringing precious (energy) resources to appreciated (energy) consumers. Interested in the Total Product Chain Responsibility? Then have a look at an example, see the story of stuf.

To promote re-use, recycling and other forms of recovery,
GPX products will meet the directive for Waste Electrical and Electronic Equipment (WEEE)
