optimal capacitors Replacement in radial distribution systems

ABSTRACT:

The main objective of the present work is to determine optimal location and size of capacitors in radial distribution systems to improve voltage profile and reduce the active power loss. For this, an effective load flow solution is essential.

In this project, Vector Based Distribution Load Flow (VDLF) method is used. The VDLF is made powerful by using the ‘Sparsity Technique’. Optimal Capacitor Placement and Sizing are done by ‘Loss Sensitivity factors’ and ‘α-coefficients’ respectively. The concept of ‘Loss-Sensitivity Factors’ can be considered as new contribution to the area of distribution system studies. From a single base case load flow study results, the “Loss-Sensitivity Factors” offer the important information about the sequence of potential nodes for capacitor placement.

The evaluation of Loss-Sensitivity Factors is well supported by the effective data structure proposed in sparsity technique. Loss sensitivity factor is defined in two ways and the results obtained using both the ways are compared.

The concept of ‘α-coefficient’ is reported for reactive power planning in power system and the application and validity of these coefficients in distribution systems for optimal capacitor sizing is investigated and found to be very effective. The algorithm in this project using α-coefficients makes the load flow solution simple, accurate and numerically reliable with reduced memory and execution time.

The above approaches are tested on 15 & 31 bus distribution test systems and results are promising.
