The challenge when using Avrora or some other MCU simulator, is that the MCU is often only a small part of the energy consumption. With TinySec, something like Avrora might be ok, as long as you are sure that the code changes will not have any side effects outside of the processor. If your extra cycles cause you to leave the radio on for a longer period of time, for example, then you need to make sure that's accounted for.
You can always just hook it up to some kind of power meter, and measure it directly. If you don't have an ammeter/power meter, you can brush up on Ohm's law and us an oscilloscope or DAQ with a sense resistor in series with your mote. Either way, measuring the power is just as easy as simulating it, and you won't have to second guess the validity of your simulator.
