Biogas-powered small power generation system designed for the agricultural sector to support the BCG model in Thailand

Abstract

This study presents the design of a small grid-connected power generation unit for farming systems to support the Bio-Circular-Green Economic Model (BCG) in Thailand. We focus on using the remaining agriculture waste resources to be reused according to the circular economy in the BCG model. Biogas was used as the primary fuel for an internal combustion engine, with gasoline and LPG as the immediate emergency reserves. We have integrated an engine to transmit power to a self-excited induction generator and designed a grid-connected inverter control strategy based on PQ control for the power conversion of the system by using digital signal processing. Using interface-based Internet of Things, devices can be wirelessly connected for control and logging data via a dashboard application.
