Stephen:
For hydro plants with reservoir, the way I have done this is by
assigning a daily (or weekly, depending on the length of the planning
horizon) amount of energy as the initial storage state, to be used
throughout the horizon optimally. As for the cost, it could even be
zero; the price of water will be set by virtue of the thermal
generation displaced by hydro power.

Ray and all,
I was wondering if anyone has experience in modeling hydro commitment
in MOST. I understand that a comprehensive hydropower commitment
incorporates medium and long-term solutions.
However, I am hoping to build a simplified model that possibly assumes
energy constraints on the hydro at the daily or weekly level, and then
looks to solve hourly commitment based on these constraints. Have
other people incorporated hydro in some way? Perhaps there is a way to
consider it a form of storage that can only be externally recharged
(through rainfall)? Do I develop a profile in order to have a
time-dependent cost function? Any help on the matter would be greatly
appreciated!
