Abstract: Distributed Generation (DG) and its interconnection to the AC power grid is a relatively new concept. DG employs small generators, which are distributed throughout the power system. The electricity is usually generated by renewable energy sources such as wind, hydro and tidal, which are intermittent in nature. These generators connected to the AC grid may lead to severe power quality problems. The issues are the voltage dip while connecting/disconnecting the generator, and unbalanced and distorted power supply. In this paper, the power conditioning of a micro-hydro-driven induction generator connected to the grid using a Battery Energy Storage System (BESS) is simulated for voltage regulation, load balancing, load levelling, harmonics reduction and voltage dip mitigation during motor start-up.

Keywords: battery energy storage systems; BESS; distributed generation; DG; induction generators; power conditioning; power quality; microhydro turbines; renewable energy; simulation; voltage regulation; load balancing; load levelling; harmonics reduction; voltage dip mitigation; motor start-up.
