Design and Assessment of a Standalone Hybrid Mode Microgrid for the Rohingya Refugees Using Load Following Dispatch Strategy

Abstract

In this research, a stand-alone PV/Wind/Diesel Gen-erator/ Battery-based hybrid microgrid for a Rohingya refugee community in Kutupalong, Ukhia, Cox's Bazar, Bangladesh, is optimally designed and assessed. Its power system responses are considered and a load-following dispatch strategy is implemented. A previous study on this topic, in which a dispatch strategy and power system response-based analysis was not conducted for the design of an optimal microgrid for the same proposed location, was used as a reference. In this current study, the optimal costs, component sizes and greenhouse gas emissions of the proposed microgrid were reduced by significant amounts compared with those in the referenced one for the similar load profile of 29.44 kW by implementing load-following dispatch control. HOMER Pro was used to obtain optimal sizing and the microgrid's design, and Simulink for power system responses. This analysis would also be suitable for other locations with identical meteorological and load profiles.
