Dynamic modelling and analysis of dc micro grid is connected to submarine power system to improvement of stability using droop control

Abstract

Electricity usage is increasing day by day but we are unable to supply it. It needs to increase the use of renewable energy sources. Micro Grid is an alternative system to meet the rapid load changes in future with the hybrid energy system (HES). In this paper, the micro grid is constructed with combines battery and super capacitor to store the electrical energy, and the power management is done using the drop control strategy. The system is designed so that the micro grid can withstand different load challenges like step and pulse. The severity of the loss due to the sudden changes in submarine (SM) power system (SPS), voltage differences occur, it has to escape use the DC micro grid in this process analyzing the power controlling of DC micro grid, the battery, the super capacitor connected to the SPS power grid using Mat Lab/simulink.
