1) Consider two interconnected areas as follows: The connected load at 60 Hz is 30,000 MW in area 1 and 10,000 MW in area 2. The generation is 32,000 MW in area 1 and 8,000 MW in area 2. The load in area 1 varies 1.5% for every 1% change in frequency while in area 2 the load varies 2% for every 1% change in frequency. Area 2 is importing 2,000 MW from area 1. The speed regulation, R, is 4% for all units. Area 1 is operating with a spinning reserve of 2,000 MW spread uniformly over a generation of 10,000 MW capacity and area 2 is operating with a spinning reserve of 1,000 MW spread uniformly over a generation of 4,000 MW capacity.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
