Why the ERCOT ORDC Splatters on the 2,000 MW Cliff : A Mathematical and Graphical Explanation
The Electric Reliability Council of Texas (ERCOT) operating reserve demand curve (ORDC) is a complex mathematical tool used as the ERCOT market's scarcity pricing mechanism. For it to be improved, it must first be understood. This work explains why the curve does not produce a loss of load probability equal to 1.0 when reserve level equals zero or the administratively imposed zero at the minimum contingency level (MCL or X)
