Analysis of Power Quality and Technical Challenges in Grid-Tied Renewable Energy

Abstract

The transition of power generation from fossil fuel to renewable energy is a cutting-edge phase in smart grid research. Renewable energy sources (RES), such as solar, photovoltaic, and wind are gradually overtaking other sources as the most attractive alternative within the power generation and distribution systems across many nations. Reduction in the carbon footprint is a major consideration in the choice of the RES. However, the technical challenges with RES pose a significant barrier to unified integration, even though the high penetration level appears plausible. The challenges are majorly caused by the variability and unpredictability of these sources. It is therefore a stimulating task to efficiently manage the electrical power distribution systems in the face of renewable energy integration. The purpose of this study is to examine the potential of renewable energy integration and the accompanying technical challenges that include power quality issues associated with grid-tied renewable energy (GtRE). The study also recommends techniques capable of mitigating prominent power quality challenges to guarantee seamless renewable energy integration in power systems.
