Enhanced Power Quality In Hybrid Power System With DSTATCOM For Grid Connection

Abstract

The utility load is currently facing new challenges in terms of power quality, voltage stabilization, and efficient energy usage due to the increased utilization of circulated power sources in the power grid. Surrounded by the renewable power sources, wind and solar are considered the most reliable. However, relying solely on either photovoltaic or wind energy systems can lead to unstable electricity production due to the unpredictable nature of wind and solar irradiance availability. To address this issue, a Hybrid system of Solar and wind energy generation systems can provide a promising and dependable electricity supply. This paper presents a model of a hybrid system connected to the grid. This technology can greatly benefit remote users, especially in regions where grid combination is not cost-effective. Though, connecting power electronics to distributed generation systems can result in significant issue created by power quality like: production of harmonic and adjustment of  reactive power, which can interrupt the distribution system. The paper contains a software simulation model of the hybrid power system and analyzes its performance in grid linked mode. The quality power of the hybrid system is evaluated by calculating the THD at various wind speeds. The utilization of DSTATCOM has enhanced the power quality of this hybrid system.
