30 square kilometers is 3e7 m^2. 2000 MW is 2e9 W. So you're looking at less than 70 W/m^2.
For comparison, the solar constant [1] is more than 1300 W/m^2.
So, no cooking.
Also, the receivers would be microwave antennas on poles, i.e. they wouldn't monopolize the land they stand on. There is concept art from the 70s showing cows grazing between/under them.
