Optimal Sizing and Allocation of Capacitors in Radial Distribution System using Sine Cosine Algorithm

The present work implements Sine Cosine Algorithm (SCA) for obtaining optimal location and size of capacitor banks for addressing problems like voltage instability and line losses in radial distribution systems. By using power loss index (PLI) method, the buses that are more sensitive to the capacitor placement are identified and, thereafter, the location and size are optimized by using proposed SCA. The main objective of the system is considered as the minimization of the total cost. The algorithm is implemented on 33 bus and 69 bus test systems and the results obtained are compared with those yielded using other algorithms.
