Abstract


Optimal selection and location of switching devices is important in distribution power system planning and reconstruction. Based on the cost-benefit analysis, this paper takes into account the reliability worth in distribution network planning and uses Differential Evolution Algorithms (DE) to solve the optimal switching device placement problem for the first time.(1)In this thesis, an analytic reliability algorithm, in which the reliability indices such as ENS are expressed as polynomials of 0-1 switch variables, is proposed firstly. Then, the feeder automation planning is formulated as an optimal switch placement problem. A new binary programming is employed to solve this problem.(2)A model based on DE for optimal switching devices (OSD) in EDNS is proposed. The optimal number and position of Switching devices, reliability, investment and outage loss of EDNs can be determined by the proposed algorithm. DE is proved to be good convergence and quick convergent speed by the numerical results.
