Wind Integration: An Emerging Paradigm

Republished from Aug. 20th, 2007. There is a need for a change in mental models to integrate wind to power systems operation. Several generative dialogue suggestions are given to apply the fundamentals of EWPC.

After reading the article by Sandy Smith, Communications Coordinator, Utility Wind Integration Group, some of its references, the articles by Roger Arnold, and all of the really valuable comments on all 4 articles, I like to select what J. Charles Smith wrote in the article Winds of Change as a summary message:

For many of us, this has created the necessity of a fundamental realignment in our thinking. We must understand all the implications of this and go about the business of helping to create the future.

The following are my generative dialogue suggestions (I am not my opinion) for a fundamental realignment in our thinking :

1) A carbon tax should be negotiated on a global setting, i.e. the World Trade Organization. Each country that does not apply the negotiated tax, will then free ride the global system.

2) Most of the discussions are indirectly supporting generation as a monopoly. Generation competition is not only possible, but absolutely necessary to go forward.

3) Wind generation variability is an important consideration, but wind generation uncertainty is even more important. Power system systemic risk management of system failure (system security) responds to uncertainty. Supply side management of systemic risk of system failure should be complemented by demand side management of systemic risk of system failure. See An Alternative Business Case for Demand Response and a Dominican strategy.

4) Wind generation best performance will come from balancing areas, in which generators are widely dispersed and mostly located in the distribution system. Open transmission access is insufficient to integrate wind generation in the state of the art.

5) There is thus a need for full transportation access. Transmission and distribution reintegration requires dismantling native loads, which changes the concept of a utility to wires only utility. See NERC Compliance and Power Sector Structure.

6) Fully functional and competitive wholesale and retail markets can then allow the development of the resources of the demand side. See We Need 2GRs as the Forecast is Always Wrong.

All of the above implies an emerging EWPC is Pragmatics' Winning Market Architecture and Design.

To go forward to EWPC as the End-State of the electricity industry for quite some time, I made a presentation at Carnegie Mellon University that can be found on the Grupo Millennium Hispaniola Blog, as A Generative Dialogue to Reach the End-State of the Power Industry.
