Wind-Driven Position Sensorless Switched Reluctance Generator and Diesel Generator Based Microgrid for Optimal Fuel Consumption and Power Blackout Mitigation

Abstract

This paper proposes a battery-supported wind power generation system (WPGS) with a mechanical position sensorless switched reluctance generator (SRG) and a diesel generator set (DGS) to enable uninterrupted electricity to remote locations. A sliding mode position observer (SMPO) estimates the SRG speed and position based on the generator voltages and currents. The proposed control approach enhances the consideration of dynamic variations in demand and generation in light of the potential for off-grid operation of small-scale WPGS in regions with a weak or nonexistent grid. Diesel engines perform best at 80%-100% of full capacity. At this mechanical loading, CO and other greenhouse gases are the lowest. The proposed approach keeps the DGS at 80%-100% loading regardless of mechanical load to maximize efficiency. In such a microgrid, the power quality (PQ) concern is dominant due to the use of local nonlinear loads. Hence, a joint logarithmic hyperbolic cosine adaptive filter (JLHCAF) is designed for the microgrid to mitigate the PQ issues emerging due to the nonlinear loads.
