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, total copper loss at peak load is 300 KW and 0.06 $/kwh. Derive the necessary equations and calculate the following: a. The load factor of the feeder b. The loss factor of the feeder c- the total annual energy cost in $ due to copper losses Suppose that a primary feeder is supplying power to a variable load.
