- Abstract
- It is demonstrated that compensating of reactive power increases the voltage profile improvement in a distribution system especially in rural networks or industries which are so far from high voltage substation. However, reactive power sources are expensive, needing large scale of investment. This paper presents an applicable method to define the number of static reactive power generating units and their optimal position in a radial network. The proposed method improves voltage profile and power losses simultaneously. To solve the optimization problem, simulated annealing algorithm has been used to minimize a dual fitness function consist of voltage drop and power losses. The method uses an economic criterion to choose the best number and location of reactive power sources. Finally, the proposed algorithm is implemented on a test network called “seda sima” which is one of the middle voltage networks in Bardsir city, Kerman, Iran. The simulation results using Matlab 2009a are presented by verifying the effectiveness of the proposed method.
