Problem Statement

The problem posed to MISG 2007 is to explore the implications of two ways of managing – and exploiting – the unpredictable ramping of wind generation, by:
• Wind/hydro matching: by matching each wind station with a hydro station (New Zealand has abundant hydro generation already). Hydro stations have very fast ramp rates, so where the wind farm and hydro stations are co-located this can be a perfect match. The problem is that they are not co-located.
• Wind sloshing: by having a large enough portfolio of wind regionally or nationally that “random” changes in one wind farm will, to a degree, be offset by random changes across the portfolio, for which the technical term “sloshing” has been coined.
