Calculation of Helping Load and Helping Flow. The Nodal Load for a load bus with a negative or zero nodal distribution factor is a helping Load, defined as HLoad, and the Nodal Flow for that Load is helping flow, defined as HFlow. To identify helping Loads that have a material impact on the Generator Deactivation Reliability Need, the ISO will calculate a helping materiality threshold, defined as HMT, as follows: Where m is for the total number of Subzones and n is for the total number of load buses in a given Subzone.
