Effective Utilisation of Weakly Meshed Distribution Network with DG and D-STATCOM

摘要

Renewable energy sources-based distributed generation (DG) integration is becoming the integral part of the present-day active distribution networks in the competitive environment. Distribution Static compensator (D-STATCOM) devices are playing a key role for better management in terms of planning the reactive power deployment for maintaining the better voltage profile and reduction in the line losses. In this article, a steady-state analysis of mesh distribution system has been carried out with installation of DG and D-STATCOM with large industrial load under load growth scenario. The major objectives of the manuscript are (i) finding the best possible place for D-STATCOM as per proposed new sensitivity index, (ii) sizing of D-STATCOM using variational algorithm based on minimum total cost of energy loss criteria, (iii) determination of percentage feeder released capacity and annual savings in cost of energy loss with DG or/and D-STATCOM. (iv) comparative analysis with simultaneous and individual allocation of DG and D-STATCOM.
