Voltage Control of 11-kV AC Grid Using STATCOM Fed with DC Microgrid

This paper is focused on the voltage control on an AC grid using STATCOM fed with a DC microgrid. This will enable to address the ability to integrate microgrids, which are based on renewable energy sources, with the AC power grid under various operating conditions. The usage of STATCOM provides the ability of AC grid voltage stability by feeding the appropriate reactive power. The design of STATCOM voltage control system is developed based on the parameters of the AC grid. The control system is adjusted to be active in the various operating conditions. The simulation study using PSCAD package is achieved to study the effect of STATCOM-microgrid system on the voltage of the AC power grid. This paper represents the first step of full integration between the AC power grid with DC microgrids to transfer both active and reactive power under various operating conditions.
