Abstract

Static Compensator (STATCOM) has been widely proposed for power quality and network stability improvement. It is easily connected in parallel to the electric network and has many advantages for electrical grids. It can improve network stability; power factor, power transfer rating. It can also avoid disturbances such as voltage sag (dip) and swell which is the main concern of this paper This paper uses a single phase multilevel inverter for STATCOM. It also implements a new current mode controller to control a STATCOM. In order to detect voltage sag, the STATCOM utilizes Goertzel algorithm which is more efficient and practical compared to available methods. Finally, simulations show the results of STATCOM operation for sag mitigation. The results show that the proposed controller can effectively mitigate voltage sag during disturbances
