It is simply intended to be a piecewise linear approximation to the kind of capability curve exhibited by many types of conventional generators, such as this one from Figure 2 in [1]. > 2.

The answer to this one is readily available in the list archives ... e.g. http://www.mail-archive.com/[email protected]/msg00817.html > 3.

Could you please address it? I'm not aware of a method to maximize profits, since that would involve an objective that is a function of price, a very unconventional type of optimization problem. You can compute revenue directly as the product of quantity and price, and the cost is available in the dispatch matrix returned by runmarket. See help idx_disp for a description of each column of the dispatch matrix. - Ray [1] http://www.hydroworld.com/index/display/article-display/353952/articles/hydro-review/volume-28/issue-2/feature-articles/system-protection/coordinating-generator-protection-and-controls-an-overview.html -- Ray Zimmerman Senior Research Associate 419A Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645
