Abstract
This paper deals with the reduction of power drawn from the supply system during generation un-certainties in D.C Micro grids using D.C Electric springs. In this work supply system is modeled using a fluctuating power source and a battery i.e. during generation uncertainties the system runs on battery support. A small micro grid system which has a critical load and non-critical load has been taken for the study and the simulations are done in MATLAB. The objective of the proposed work is to conserve power by making the non-critical loads draw less power during generation uncertainties which in turn relives the battery and renewable generator to the possible extent. D.C Electric springs are extension to A.C Electric springs used in A.C systems which make the non-critical loads draw less power by adjusting the voltage supplied to them. The D.C Electric spring presented in this work is different from the existing technologies present in the literature in terms of the circuitry used and its interpretation with mechanical spring.
