Series active compensator (SAC) is a custom compensator utilized in power distribution network, however, due to connected in series with distribution line then SAC would suffer from large current flows due to downstream faults. To limit the flow those fault currents and protect SAC itself as well, a fault current limiting (FCL) function is proposed. Fault current limiting function of SAC will be activated...
Recently, solar energy generation and wind power generation have been introduced to electric power system. But, as for this natural energy, influence such as frequency fluctuation is exerted on electric power system, which is a fundamental problem in operation of a small grid system such as micro-grid. These systems should provide appropriate power quality compared to a large grid. However, using...

Wind power generation using an unlimited, natural energy is getting an attention regarding environment issues in recent years, and the installed capacity of wind power generation system is increasing at a rapid pace, resulting in deterioration of power quality especially frequency and voltage. This fact will be a big problem to restrict large capacity of wind farm. This paper proposes a new frequency...
