In recent times, renewable energy sources such as wind, solar, and micro-hydro have seen increased usage for electric energy generation. This paper presents a wind-based standalone hybrid energy system designed for remote area power applications. There is still significant growth potential in the field of renewable energy resources in the coming years.
With the renewed interest in wind turbines as an alternative energy source, induction generators are being considered as a viable alternative to well-developed synchronous generators due to their lower cost, inherent ruggedness, and simplicity in operation and maintenance. Induction generators can generate power at varying speeds, making them suitable for self-excited standalone (isolated) mode and grid-connected mode, supplementing local loads alongside synchronous generators. Extensive research is being conducted to select an appropriate generator for standalone Wind Energy Conversion Systems (WECS). To ensure a continuous power supply, suitable storage technology is used as a backup.
Energy Storage Systems (ESSs) play a vital role in wind power applications by controlling wind power plant output and providing auxiliary services to the power system, thereby enabling increased integration of wind power. A charge controller for the battery bank, based on turbine Maximum Power Point Tracking (MPPT) and battery State of Charge (SoC), is developed to ensure controlled charging and discharging of the battery. The mechanical safety of the WECS is assured using a pitch control technique. Both control schemes are integrated, and their efficiency is validated through various load and wind profiles in MATLAB/SIMULINK
