Define final values for nfr_energy and nfr_safety

[marioney]

@chcorbato @darkobozhinoski We need to define these values before we can run the experiments.

Default values are nfr_energy=0.5 and nfr_safety=0.8

[marioney]

Defined values:

nfr_energy=0.7
nfr_safety=0.4

Also increase in power will be 0, 1.3and 1.5
