Executive Summary

One of the biggest distributed power generation success stories is the deployment of wind power - now the world's fastest-growing energy source. Since 1993, the market for new tur-bines to generate clean power from wind has grown at over 40 % per year. Already over 25,000 turbines (some 10,000 in Germany) are producing electricity world-wide at the end of 2001.

It is not sufficient to develop distributed generation systems that only produce electric power. Fully automated - remotely supervised - systems that require little or no human intervention seem to be ideal. Technologies bundled into the distributed generation system, therefore, has to include interfaces to supervisory control and data acquisition (SCADA) of control centers. Additional applications that are necessary for a complete system may include: metering, protection and control, remote monitoring and fault diagnosis, automated dispatch and control, data retrieval, site optimization of electrical/thermal outputs, asset management, as well as condition monitoring and diagnosis.

Globally, utility deregulation is expanding and requiring demands to integrate, consolidate and disseminate real-time information quickly and accurately within all kinds of utility automation systems - from power plants to customer interfaces. Utilities and vendors spend an ever-increasing amount for real-time information exchange; costs for data integration and maintenance are exploding. Vendors of power systems have - because of the fast growing market - very limited resources to implement and apply hundreds of proprietary communication systems. In response to this situation, the IEC (International Electrotechnical Commission) and IEEE have developed and published a suite of (draft) international communication standards and a technical report.

The future electricity systems will - thanks to a seamless real-time communication system - be smart at the top but smarter at the bottom, self-regulated by millions of communicating devices connected to form feedback loops, and permanently aware of the world around them.

This paper gives an overview on utility's crucial integration requirements, the IEC 61850 standardization and the IEEE UCA (Utility Communications Architecture™) solution, and the global market acceptance of this new technology.
