Frequency response of prime movers during restoration

In the initial phase of restoration, operators are often concerned with the size of load which can safely be picked-up, and the effectiveness of the g eneration reserve. There has been a need for a methodology to readily addre ss these concerns by providing simple guidelines to facilitate an orderly p ower system restoration. In this paper, a simple approach is developed based on an approximate frequ ency response rate of prime movers for determining: (a) the maximum load pi ckup within the allowable system frequency dip, and (b) the amount and dist ribution of reserve for maintaining firm generation.
