摘要

Background: Introduction of capacitor into a radial distribution network can bring about power loss reduction, minimization of total cost due to power loss and compensation, improvement of network voltage profile and stability index. This depends on the deliberate placement and sizing of shunt capacitor as improper allocation may yield negative results. Hence this paper aim to minimize the compensation cost, reduce total power loss, improve the voltage profile and stability index by the way of optimal placement and sizing of one to three shunt capacitors using Cuckoo Search Algorithm as optimization technique. Methodology: In this paper, the objective function is the minimization of the total annual cost due to the radial distribution system power losses and reactive power compensation subject to the operating constraints. The cost of reactive power compensation includes purchase, installation and operating cost of capacitors. The applicability of the proposed method was tested on the standard IEEE 33-bus and Ayepe 34-bus Nigerian radial distribution network of the Ibadan Electricity Distribution Company. Four test cases were considered for the two test systems which are the base case, one, two, three installation of shunt capacitors. Results: The simulation results of the four test cases obtained were compared. The results demonstrate that the proposed method is capable of saving significant amount total annual cost, reducing total power loss and attain improvement in voltage profile and stability index. The rate of improvement of the results tends to be insignificant as the number of capacitors optimally were increased beyond two. Conclusion: Optimal allocation of capacitors in the radial distribution system is capable of improving the efficiency of the system.
