Design and optimization of DC-grids power exchange

Abstract

A dominance-based power exchange mechanism between DC grids has been presented and investigated to enable macro-optimization of power supply capacity. Furthermore, a MATLAB/Simulink simulation model is created to calculate the power loss and renewable energy ratio for the power exchange while taking transmission voltage and transmission power into account. As a result, the proposed power exchange method’s effectiveness in terms of power exchange between on- and off-grids is demonstrated. Furthermore, adjusting the aforementioned parameters can lower the amount of power drawn from the utility grid, illustrating the significance of optimizing the parameters to optimize power exchange functioning.
