This research focuses on the application of the Direct Torque Control (DTC) strategy to manage the terminal voltage of a Self-excited induction generator (SEIG) that supplies power to an autonomous load. The SEIG is connected to a three-level Neutral Point Clamped (3L_NPC) converter. The utilization of the 3L_NPC converter ensures the increase in generated voltage levels, leading to improved current waveform quality and reducing the Total Harmonic Distortion (THD) in the stator currents. To ensure a more stable and dependable power supply, this study also introduces an Energy Storage System (EESS) consisting of batteries (BT) along with a management algorithm designed to oversee power flows between different storage devices. Furthermore, the dynamic model of the SEIG incorporates the saturation effect of magnetic materials and is conducted in the frame using the Concordia transform. The efficacy of the proposed control strategy is verified through simulation tests conducted in MATLAB/Simulink.

Diesel Generator set was found to be a favorite power generator in a remote area. In this area, diesel genset usually consumes a significant amount of diesel fuel with higher fuel price than an urban area. Diesel Generator capacity conventionally prepared twice bigger or more than the existing load to prevent any load spike from designated equipment. This work implements an Energy Management System to cut the spike with the support from battery storage unit and photovoltaic module. Once the Energy Management System cut the load spike using battery/photovoltaics, Diesel Generator loads no longer need to be irrelevantly bigger than the existing load. The current experiment in the remote island at Raja Ampat archipelago indicates that the using of 80 kVA Diesel Generator can be reduced to 42 kVA Diesel Generator. This Diesel Generator replacement induces fuel consumption up to 50 %. With this designed work, a smart microgrid with PV-Battery-Diesel can be installed in a designated remote area with lower fuel consumption.
