An Enhanced Method for Determination of the Ramping Reserves

Power generation reserves play a central role for maintaining the balance of generation and consumption. Reserves, scheduled in advance, compensate for forecast error, variability and transmission losses. However, as reserves are a costly commodity, their amount should be carefully assessed to prevent unnecessary expense. Currently, the quantity of required reserves are determined based upon a posteriori methods that use operator’s experience and established assumptions. While these assumptions have been made out of a level of engineering practicality, they may not be formally true given the numerical evidence. The earlier “sister” paper to this work presented a method to determine the quantity of load following reserves a priori. This paper now uses a similar methodology to determine the quantity of ramping reserves.
