Control of wind-solar microgrid for rural electrification

A wind-solar microgrid (MG) is investigated to work in isolated and remote areas where abundance of renewable sources i.e. wind, solar, hydro etc. are available. The constant speed wind generation is achieved with permanent magnet synchronous generator (PMSG) and solar panels are used to generate DC power from the sun light. A boost converter is utilized to fetch this solar power to loads and the battery bank using incremental conductance (INC) approach. This battery bank is paralleled at the DC bus of the VSI (Voltage Source Inverter). The normalized sign least mean fourth (NSLMF) control is applied to provide power quality solutions like harmonic suppression, voltage regulation, the reactive power compensation and power balance etc. A MATLAB-Simulink model is developed to demonstrate the performance of the microgrid.
