Transient performance improvement of grid connected hydro system using distributed generation and capacitive energy storage unit
In this paper, distributed generation (DG) consisting of wind turbine generators, aqua electrolyzer, fuel cells, diesel engine generator, and energy storage devices like flywheel energy storage system and battery energy storage system are considered along with conventional hydro power generation with electric governor. The hydro generator is equipped with automatic voltage regulator, IEEE type dual input power system stabilizer like PSS3B and integral controlled automatic generation control (AGC) loop. The different tunable parameters of the power system model are optimized by a novel craziness-based particle swarm optimization with wavelet mutation (CRPSOWM), developed by the authors. While integrating the DG with the hydro power system, improved transient performance is observed. The usage of capacitive energy storage unit in the AGC loop of conventional power generation unit provides further improvement in the transient performance. The proposed CRPSOWM incorporates a wavelet-theory-based mutation operation and offers robust and promising results.
