If I have a number of op-amps on a circuit, how do I calculate the power consumption? Do I consider only the quiescent current?

Your circuit looks OK , what is your load resistance and load impedance?
What is you current power consumption? (V & I in no load)
What is your power consumption when applying dc voltage and connecting the input to GND and out put floating ?
All the best

The rms value and average value are different.
Positive value means the current flow from the power supply and the negative value means the current flow into the power supply.
For the negative value ,the power supply acts as a load.the load acts as a source.
So the power consumpted by the load should be substracted.

As we know, MCML draws static power which equal to, P=IV. As far as i know, static here is not mean on leakage and subthreshold. It refers to current source at the tail of the MCML. Let say I want to reduce the power consumption, I can simply change Vdd and current source. Or there is other effective ways/techniques to reduce it ?

in some cases there is.. for example.. you can increase the parallelism in the circuit and reduce the clock frequency to get the same throughput. In this case since clock is decreasing with increase in area . so power decreases.
But in general lower gatecount means lower power assuming same CLOCK , similar switching activity...

You can calculate the average current drawn from power supply. In the "Output / Setup..." of ADE, you can enter the following express to calculate average current of a voltage source (V1):
where V1 is the name of a voltage source. You may need to calculate average current of VDDA and VDD.

In most cases the input power used in PAE formula is neglected compared to output power (due to high gain of the amplifier).
So, never you get high PAE and high power consumption in the same time.

The Family of logic parts (Cmos, TTL or other) determines its power consumption when it is sitting doing nothing or is switching slowly.
I doubt that a datasheet or a simulation program will tell you the power consumption when it is switching at a high frequency.
