[Greenbuilding] Using the grid as a battery

[Nick Pine]

... a simulation could have 1 minute time steps and 100 virtual pulse 
generators activated by individual accumulators that add a fixed amount dT 
from a uniform random number generator with each time
step, proportional to the daily source frequency, plus another amount dS 
proportional to source correlation from each pulse generator with an active 
output. When an inactive pulse generator accumulator reaches a fixed 
threshold, we could dump its accumulator and fire its output for a random 
interval with the average source duration.

For example, 100 sources with 4 hour/day average durations and 0% 
correlation and a 0.5 firing threshold would have 24hx60mxdT = 0.5, ie dT = 
0.000347 and dS = 0.

With 20% correlation, dT = 0.8x0.000347 = 0.000278. The average number of 
active sources would be  100x4h/24h = 16.7, and 16.7dS = 0.2x0.000347 makes 
dS = 4.16x10^-6.
