Energy savings using D-STATCOM placement in radial distribution system

In this paper optimal location and size of D-STATCOM is determined for radial distribution networks for loss reduction, improvement of voltage profile and overall energy saving. The main contribution of the paper is: (i) Comparison of D-STATCOM allocation for radial distribution network using voltage stability index and power loss index approach (ii) D-STATCOM size calculation by variational technique for radial distribution system, (iii) percentage reduction in power losses with D-STATCOM placement. Based on the reduction in the power losses, the energy savings have been determined. The proposed method is tested for D-STATCOM allocation in IEEE 33-bus radial distribution systems. Results show the considerable reduction in losses and improvement in voltage profile. (C) 2015 The Authors. Published by Elsevier B.V.
