DESIGN METHODOLOGY OF A HYBRID RENEWABLE ENERGY MICROGRID FOR AN ISOLATED RURAL COMMUNITY. APPLICATION CASE IN ZAMBIA

This research tackles the problem of designing reliable off‑grid power systems for isolated rural villages that have never had grid electricity, focusing on Mumbeji, Zambia. The paper lays out a step‑by‑step, multi‑phase method that includes Data Collection, Assessment, Planning/Modelling, and Execution. Instead of only doing techno‑economic optimization, the method also brings in social factors, like co‑designing with the community and setting up a local renewable‑energy group, to make the project last. Technically, the work estimates the community’s electricity demand curves, evaluates local solar and wind resources, and models a hybrid microgrid layout. For B.Tech students, this framework serves as a hands‑on guide for sizing hybrid PV‑battery‑diesel or wind systems. The

paper describes the basic method and early demand‑generation curves, but long‑term operation data and experimental testing of the actual microgrid are still limited to the early stages. This resource helps turn community resource assessments into simulated microgrid designs using standard engineering tools.
