Introduction

Hybrid solar-wind energy systems have emerged as a viable solution to address the increasing global demand for sustainable and reliable electricity [1]. These systems integrate solar photovoltaic (PV) and wind turbine technologies to harness renewable energy from multiple sources, thereby mitigating the intermittency issues associated with standalone renewable energy systems [2]. The complementary nature of solar and wind resources ensures a more consistent energy supply, as solar generation peaks during daylight hours while wind energy production can occur throughout the day and night [3]. By combining these two energy sources, hybrid systems enhance energy security, reduce dependency on fossil fuels, and contribute to the decarbonization of the power sector [4]. The deployment of hybrid solar-wind systems is particularly advantageous in remote and off-grid areas, where access to conventional electricity infrastructure is limited [5]. These systems not only provide clean energy solutions but also support economic development by enabling electrification in underserved regions [6]. 

The efficiency of hybrid solar-wind energy systems is highly dependent on optimized system design, which involves selecting appropriate components, determining the ideal power generation capacity, and integrating energy storage solutions [7]. Energy storage plays a crucial role in balancing fluctuations in power generation and ensuring a continuous energy supply. Batteries, supercapacitors, and other advanced storage technologies help store excess energy generated during peak production periods for use during periods of low generation [8]. Power electronics and intelligent control systems are essential for ensuring the smooth operation and seamless integration of different energy sources [9]. Hybrid energy systems must be designed to operate efficiently under varying climatic conditions, requiring robust energy management strategies and adaptive control mechanisms [10].
