The presence of real and reactive power mismatch leads to change in ____________ in islanded microgrid. Frequency Voltage Both of these None of these

The presence of real and reactive power mismatch leads to change in both Frequency and Voltage in an islanded microgrid.

Here's why:

1. Real Power Mismatch: In an islanded microgrid, if there is a mismatch in real power (the power that actually does work), it directly affects the frequency of the system. If generation is more than the load, frequency will rise and if generation is less than the load, frequency will fall.

2. Reactive Power Mismatch: Reactive power (the power that oscillates back and forth) mismatch in an islanded microgrid leads to voltage changes. If reactive power generation is more than the load, voltage will rise and if reactive power generation is less than the load, voltage will fall.

So, the answer is "Both of these".
