Abstract

Abstract: —- The main objective of this paper is to create a smart dc micro-grid capable of 100% autonomous zero net electric energy in the cluster of buildings to facilitate a low-carbon sustainable electricity supply system under considerations of urban and rural scenarios. The propose model comprises of house clusters with an autonomous communication developed for the residential area, taking the consideration of stochastic behavior of wind and solar irradiation. Voltage droop and Slope compensation peak current mode control technique for the synchronous bidirectional boost converters is employed for the energy storage systems (ESSs). The bidirectional converter stage for house clusters plays a pivotal role in standalone operation. In case a battery pack is laid off from any house cluster, the dc bus voltage still be stabilized due to the proximity bidirectional converter stages of other house clusters or community bank. The houses in the cluster comprise of permanent magnet synchronous generator (PMSG), solar photo voltaic (PV), battery bank and variable load. The proposed model is simulated on MATLAB/Simulink environment and suffices the real time environment.
