A review of study on hybrid solar PV and Wind energy system

Because solar and wind power are inherently intermittent and unpredictable, increasing their penetration in current power systems may pose significant technological difficulties, particularly for weak grids or stand-alone systems without enough storage capacity. The impact of the fluctuating nature of solar and wind resources may be partly addressed by combining the two renewable resources into an optimal combination, and the entire system becomes more dependable and cost-effective to operate. The difficulties and possibilities/solutions of hybrid solar PV and wind energy integration systems are discussed in this article. Voltage and frequency fluctuation, as well as harmonics, are significant power quality problems for both grid-connected and stand-alone systems, with the latter having a greater effect when the grid is weak. This may be addressed to a great degree via appropriate design, sophisticated rapid response control capabilities, and hybrid system optimization. In terms of optimum size design, power electronics topologies, and control, the article provides an overview of the major research work published in the literature. The article provides an overview of the current status of hybrid solar and wind systems, both grid-connected and stand-alone.
