Optimal Capacitor Placement to Reduce Losses in Distribution System
Authors: ,
Abstract: Distribution system provides a final link between the high voltage transmission system and the consumers.To improve the overall efficiency of power system, the performance of distribution system must be improved. An important method of controlling bus voltage is by shunt capacitor banks at the buses at both transmission and distribution levels along lines or substation and loads. The problem of capacitor allocation in electric distribution systems involves maximizing “energy and peak power (demand) loss reductions” by means of capacitor installations. As a result power factor of distribution system improves. A 10 bus radial distribution system is taken as model. The load flow program is executed using Fuzzy Logic toolbox of MATLAB. Fuzzy logic based technique is used for determination of suitable location of capacitor placement. Shunt capacitors to be placed at the nodes of the system will be represented as reactive power injections. Fuzzy techniques have advantages of simplicity, less computations & fast results.
