How to use fuzzy logic to regulate voltage and frequency of a microgrid?

using fuzzy logic is an improved droop control. it is represented in the attachment paper. i didnt get it well. in the method do we calculate R and X of a line to use them in the GDC (generalized...

In microgrid, when there are 2 or 3 DG units connected in parallel, should they work in the common reference frame? How?

for conventional droop control, when microgrid is in islanded mode and several DG work in parallel. for simulation, How to translate the variables from an individual inverter reference frame onto...

Arena simulation - how do i model the following model in ARENA (see description) (new to ARENA)?

Hello, I'm fairly new to ARENA and I have the following problem: I have two queues in which, in each queue, a different order type arrives (both having an arrival rate of exponential 10). Order...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
