Determination of Locations for Static Transfer Switches in Distribution Systems Using Genetic Algorithms and Goal Programming

Voltage dip resulting from faults is one of the important power quality problems. Static Transfer Switches (STSes) are considered one of the efficient remedy approaches for the voltage dips. Placement of STSes considering the minimal cost in a distribution system, therefore, becomes essential for planning a system including sensitive loads. In this paper, the problem is formulated as a goal programming problem with three individual objectives. The Genetic Algorithms (GAs) using a vertex encoding/decoding are used to solve the problem. The simulation results from a 33-bus system are used to show the applicability of the proposed method.
