description | Network reconfiguration in distribution system is
realized by changing the status of sectionalizing switches, and is
usually done for the purpose of loss reduction. Loss reduction can
result in substantial benefits for a utility. Other benefits from loss
reduction include increased system capacity, and possible
deferment or elimination of capital expenditures for system
improvements and expansion. There is also improved voltage
regulation as a result of reducing feeder voltage drop. Research
work included by this paper focuses on using branch exchange
method to minimize losses and solve the problems over different
radial configuration. Solution’s algorithm for loss minimization
has been developed based on two stages of solution methodology.
The first stage determines maximum loss-reduction loop by
comparing the size of circles for every loop. In a distribution
system, a loop is associated by a tie-line and hence there are
several loops in the system. To obtain the maximum lossreduction
loop, size of modified zero loss-change circles are
compared, and the loop within the largest circle is identified for
maximum loss-reduction. The second stage determines the
switching operation to be executed in that loop to reach a
minimum loss network configuration by comparing the size of
the loop circle for each branch-exchange. The smallest circle is to
be identified for the best solution; the size of the loop circle is
reduced when the losses are minimized. The performance of the
proposed branch exchange method is tested on 16-bus
distribution systems. |
