This paper gives an overall review of the working principle of the inertial response from the synchronous condenser for frequency support in the grid. In addition to this, four proposed frequency control strategies for improvement of network frequency response by static energy storage devices, such as the Static Synchronous Compensator (STATCOM) with suitable energy storage elements or the battery...
Individual capacitor voltage balancing is one of the challenges in the field of multilevel converters, especially when the phase legs of the converter are connected in star configuration. This issue can be even more problematic when the converter is operating close to zero average current operating mode. This paper first shows the issue related to the capacitor voltage balancing at zero average-current...
Hardware in the loop (HIL) simulations are necessary in order to validate correct operation of control system hardware and software of Static Synchronous Compensator (STATCOM). These simulations are currently performed by connecting the actual control system hardware with a Real Time Digital Simulator (RTDS), which is often complex, expensive and not always readily available. This paper presents the...
