Suppose that a primary feeder is supplying power to a variable load. Every day and all year long, the load has a daily constant peak value of 50 MW between 7 PM and 7 AM and a daily constant off-peak value of 5 MW between 7 AM and 7 PM. Derive the necessary equations and calculate the following:
a. The load factor of the feeder
b. The factor of the feeder
