This paper presents an advanced dynamic voltage restorer with integrated energy optimal compensation (EOC-DVR), which combines the advantages of pre-sag and minimization compensation. The performance parameters EOC-DVR, such as compensatory capability, loss energy, duration compensation, can be balanced by this strategy. Additionally, impact on load is further reduced proposed method. By analyz...

Power quality is one of the major concerns in the present era. The problem of voltage sags and swells and its major impact on sensitive loads are well known. To solve this problem, custom power devices are used. One of those devices is the Dynamic Vol tage Restorer (DVR), which is one of the most efficient and effective modern custom power devices used in power distribution networks. A new cont...

This paper proposes a low complexity control scheme for voltage of dynamic restorer (DVR) in three-phase system. The employs the fractional order, proportional-integral-derivative (FOPID) controller to improve on DVR performance order enhance power quality terms response time, steady-state error and total harmonic distortion (THD). result obtained was compared with proportional-integral (FOPI),...
