PROJECT TITLE :

Optimal capacitor placement in distribution systems for power loss reduction and voltage profile improvement

ABSTRACT:

This study presents a two-stage procedure to identify the optimal locations and sizes of capacitors in radial distribution systems. In 1st stage, the loss sensitivity analysis using two loss sensitivity indices (LSIs) is employed to select the most candidate capacitors locations. In second stage, the ant colony optimisation algorithm is investigated to search out the optimal locations and sizes of capacitors considering the minimisation of energy loss and capacitor prices as objective functions while system constraints are totally achieved. The fastened, practical switched and the mixture of mounted and switched capacitors are thought-about to find the optimal answer. The backward/forward sweep algorithm is developed for the load flow calculations. The proposed procedure is applied to completely different standard take a look at systems as thirty four-bus and 85-bus radial distribution systems. In addition, the appliance of the proposed procedure on a real distribution system of the East Delta Network as a half of the Unified Egyptian Network is used as a test system. Numerical results show the aptitude of the proposed procedure to find the optimal answer for significant saving in the entire value with a lot of accurate and economical, competitive compared with other methods within the literature especially with increasing the distribution system sizing.
