Network reconfiguration using PSAT for loss

Journal Article

Abstract


  • 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.
