Abstract :
Control areas are held to the NERC´s control performance standards (CPS), CPS1 and CPS2. A control area serving rapid and widely varying loads would like to know how load variations in certain subareas or zones affect its area´s CPS1 and CPS2 measures. This paper addresses the question of decomposability of the 1-min average value of area control error (ACE) A~C~E~1, the primary variable in the computation of CPS1 and CPS2, into components attributable to load fluctuations within defined zones. It includes description of dynamic models of ACE and A~C~E~1, and simulated results confirming the decomposability of A~C~E~1.
