5、 p is the active power output,1 in p.u. of the DER nameplate active power rating f is the disturbed system frequency in Hz pavl is the available active power, in p.u. of the DER rating ppre is the pre-disturbance active power output, defined by the active power output at the point of time the freque
6、ncy exceeds the deadband, in p.u. of the DER rating pmin is the minimum active power output due to DER prime mover constraints, in p.u. of the DER active power rating in kW dbOF is a single-sided deadband value for high-frequency and low-frequency, respectively, in Hz dbUF is a single-sided deadband
7、 value for high-frequency and low-frequency, respectively, in Hz kOF is the per-unit frequency change corresponding to 1 per-unit power output change (frequency droop), unitless kUF is the per-unit frequency change corresponding to 1 per-unit power output change (frequency droop), unitless 1 Includes positive and negative active power for Energy Storage DER during low- and high-frequency conditions respectively. Use of alternate control means to meet this requirement is permitted.
