Reduction Power losses on distribution feeders in Electrical Distribution Systems

This paper presents a study the power losses and its impacts on distribution of electric power networks, Capacitors are widely used in distribution system for reactive power compensation to achieve power and energy loss reduction, voltage regulation, and system capacity release. The extent of these benefits will depend upon how the capacitors are placed on the system, the number and location, the type (fixed or switched), the size, and the control scheme of the capacitors. Therefore, the capacitor placement problem in distribution feeders consists of determining the place (number and location), type, size, and control scheme of capacitors to be installed such that the benefits mention above is weighted against the fixed and running costs of the capacitors and their accessories. The installation of shunt capacitors on radial distribution systems is essential for many reasons. These reasons arc power flow control, improving system stability, voltage profile management. and losses minimization By taking the twenty two nodes, and apply the MATLAB program on this network. The result improved performance of the electrical network known, control adding shunt capacitor in the exact locations as needed to improve the voltage profile and reduces power losses
