Recently, introduction of renewable energy such as photovoltaics and wind energy has gained precedence for greenhouse gas reduction and oil substitution. However, due to the power fluctuation of renewable energy sources, voltage and frequency deviation are problematic in power systems. At present, a transformerless battery energy storage system based on a cascaded multilevel converter has been proposed...
In recent years, distributed generation (DG) and renewable energy source (RES) are attracting special attention to distribution systems. RES such as photovoltaic (PV) system is used as a source of clean energy. However, the large amount of distributed generation causes voltage deviation beyond a statutory range in distribution systems. This paper proposes a methodology for voltage control by using...
Recently, operational cost for diesel generator such as fossil cost, transport cost, and storage cost are expensive in isolated island. Consequently, renewable energy generation is advanced in the world. Furthermore, all-electric house and electric vehicle carrying a storage battery is increasing. Controllable load in the grid can be installed using all-electric house and electric vehicle carrying...
Wind turbines have become the most cost-effective renewable energy systems available today and are now completely competitive with essentially all conventional generation systems. However, wind stochasticity results in fluctuations in output power as well as undesirable dynamic loading of the drive train during high turbulence. A model-based predictive control strategy for the field-oriented control...
