Abstract


Addressing power quality issues in today’s modern electrical systems have become a significantly important topic for all consumers. Power quality issues play a vital role for reliability and efficiency of electrical networks. With distributed generations and mainly solar and wind energy installations power quality issues become a challenge to tackle. Power quality issues such as voltage sag, voltage swell, load changes and harmonics can cause financial losses, distributions in the operations and damage devices and equipment that is used in facilities and in daily life. There are custom power electronic devices that can overcome these power quality issues and improve stability. To ensure stability of voltage and reduce Total Harmonic Distortions (THD), Distribution Static Synchronous Compensators (D-STATCOM) is used in this paper simulate a hybrid electrical system in MATLAB/SIMULINK as well as compared with real site data. D-STATCOM is widely used in distribution systems due to their capabilities in voltage fluctuation mitigation, reduce THD, rapid response to reactive power support and improving system efficiency. In this study, P&O control algorithm is used and D-STACOM is integrated in the work to enhance power quality in total. With the current control technic and simulation THD is reduced significantly in hybrid electrical system. The simulation result also checked with real plant data and it is clear that D-STATCOM can support plant to reduce THD and improve power quality in electrical systems.
