Control of Hybrid Wind-Diesel Standalone Microgrid for Water Treatment System Application

This article deals with the control of a standalone microgrid based on variable speed wind turbine (WT) and fixed speed diesel generator (DG) for water treatment application. A perturb and observe (P&O) method is used to achieve the maximum power point tracking (MPPT) from the WT without using s...

Description
Summary:This article deals with the control of a standalone microgrid based on variable speed wind turbine (WT) and fixed speed diesel generator (DG) for water treatment application. A perturb and observe (P&O) method is used to achieve the maximum power point tracking (MPPT) from the WT without using speed sensors. Two levels of control are proposed for the three-phase voltage source inverter for voltage and frequency regulation at the point of common coupling (PCC) and power management in standalone and diesel connected modes. Furthermore, the battery energy storage is controlled using simple approach to balance the power in the system during load variations and wind speed changes. The performance of the proposed system is tested using MATLAB/Simulink under load and weather variations. In addition, the system is tested on a small-scale prototype in the laboratory under load and wind speed variations.
