Claim 0:
1. A control system for cost optimal operation of an energy facility including equipment, the control system comprising:
a controller configured to:
provide a cost function comprising a cost term defining a cost as a function of a rate variable and an equipment usage variable;
simulate a cost of operating the energy facility over an optimization period at each of a plurality of different values of the rate variable, the plurality of different values of the rate variable defining a plurality of different costs per unit of the equipment usage variable;
select a value of the rate variable that results in a lowest cost of operating the energy facility over the optimization period;
perform an online optimization of the cost function with the rate variable set to the selected value to generate one or more setpoints for the equipment; and
operate the equipment during the optimization period in accordance with the one or more setpoints generated by performing the online optimization.
