Recloser Allocation for Improved Reliability of DG-Enhanced Distribution Networks Conference Paper uri icon

abstract

  • The radial distribution feeder protection strategy is first presented in the paper without consideration for DG. Then, the addition of DG across the feeder (constrained in terms of power and/or energy capacity) is introduced in the model. If islanded operation of these DG sources is allowed on a feeder subjected to a disturbance, DG may reduce the number of interruptions and/or durations for customers residing within their protection zones, thus increasing the reliability of service. To that end, a procedure for finding optimal positions for DG and protection devices is presented for a feeder equipped with capacity-constrained distributed generators, using a custom-tailored genetic algorithm, and the improvement in reliability is demonstrated on a test feeder. Tuning of the genetic algorithm parameters, and an adaptive algorithm that eliminates the need for parameter tuning are the subject of a separate paper by the same authors. 2007 IEEE.
