Maximum loading and cost of energy loss of radial distribution feeders
The paper presents a method for obtaining the maximum allowable loading of radial distribution feeders for different types of loads without violating the maximum current carrying capacity of branch conductors. Minimum voltage of the feeders can also be maintained by allowing the feeders to take load growth up to a specific period of time. A simple mathematical formula for calculating power loss in kth year is proposed. Another mathematical expression for the present worth of the cost of feeder energy loss over the entire life time is also proposed for different types of load modeling considering the effect of load growth, load factor and cost of energy. Results are also presented for a radial distribution feeder.
