A practical example of the use of distribution static compensator (D-STATCOM) to reduce voltage fluctuations

Voltage fluctuations at the point of common coupling of the generator to the electricity supply network are an inevitable consequent of the variable nature of some renewable energy sources such as photovoltaics and wind power. These can be mitigated by a number of equipments but the fast response of the distribution static compensator (D-STATCOM) makes it the ideal solution. The author discusses active and reactive power flows, and reactive power compensation, and then describes the D-STATCOM and an application
