Prof Zimmerman, thanks for your response I am using runopf_w_res. I agree with you, but I want to decouple the energy prices and reserve prices, because the reserve market is "pay as bid", i.e. the reserve payment doesn't depend on the reserve prices, only depend on the reserve cost. For this cause, the reserve prices must not be affected to energy prices.
Therefore, I want to formed the energy price independently of the reserve price.

I'm not sure what you mean by forming the energy price "independently of reserve prices". When co-optimizing, by definition the allocation of energy and reserves (and therefore energy prices) are interdependent. That is, the amount of required reserves and the relative reserve costs will affect the energy dispatch and the nodal marginal price of energy. -- Ray Zimmerman Senior Research Associate 419A Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Jun 29, 2012, at 11:16 AM, Santiago Chamba wrote: Hello Matpower community, I am working with joint optimization of the energy and reserve markets. The energy market is based in marginal cost, and the reserve market is "pays as bid". When I simulated a case with scarcity generating power, the all capacity of power units are dispatched for energy and reserves. In this case, the nodal price reflect of multipliers of the power unit capacity constraints, i.e. the price is modified with regard to the reserves constraints. How can I formed the energy price independently of reserves price. ? Best regards, Santiago
