Claim One:
1. A method for selecting improvements to an original distributed automation power grid, the method comprising: (a) identifying the original distributed automation power grid design as a current circuit; (b) by a processor, creating a parameterized phased-recovery survivability model of the current circuit with a selected failure event by performing a power flow analysis using a time series of load values of each of a plurality of sections in the grid at each of a plurality of times of day; (c) by the processor, determining an average energy not supplied metric of the current circuit with the selected failure event, using the parameterized phased-recovery survivability model of the current circuit; (d) generating a candidate circuit containing a modification to the current circuit; (e) by the processor, creating a parameterized phased-recovery survivability model of the candidate circuit with the selected failure event by performing a power flow analysis using a time series of load values of each of a plurality of sections in the grid at each of a plurality of times of day; (f) by the processor, determining an average energy not supplied metric of the candidate circuit with the selected failure event, using the phased-recovery survivability model of the candidate circuit; (g) substituting the candidate circuit as the current circuit only if the average energy not supplied metric of the candidate circuit is better than the average energy not supplied metric of the current circuit; and (h) repeating the operations (d), (e), (f) and (g) until the average energy not supplied metric of the current circuit meets a survivability requirement for the grid.
