Abstract—This paper presents comparative study of two sensitivity based methods namely loss sensitivity method and bus sensitivity method, for the optimal capacitor placement problem. These methods will give best capacitor locations for the reactive power compensation. Self-adaptive Differential Evolution with Neighborhood Search (SaNSDE) algorithm is used to find the optimal capacitor sizes. The performance of these two methods is compared on the basis of the active losses and voltage profile of the bus systems after optimal capacitor placement. The methods have been implemented on IEEE 15-bus, IEEE 34-bus and IEEE 69-bus radial distribution systems. The results obtained clearly indicate that bus sensitivity method based capacitor placement gives better results in comparison to the loss sensitivity method.
