Abstract
A hybrid renewable energy source (HRES) consists of two or more renewable energy sources, suchas wind turbines and photovoltaic systems, utilized together to provide increased system efficiency and improved stability in energy supply to a certain degree. The objective of this study is to present a comprehensive review of wind-solar HRES from the perspectives of power architectures, mathematical modeling, power electronic converter topologies, and design optimization algorithms. Since the uncertainty of HRES can be reduced further by including an energy storage system, this paper presents several hybrid energy storage system coupling technologies, highlighting their major advantages and disadvantages. Various HRES power converters and control strategies from the state-of-the-art have been discussed. Different types of energy source combinations, modeling, power converter architectures, sizing, and optimization techniques used in the existing HRES are reviewed in this work, which intends to serve as a comprehensive reference for researchers, engineers, and policymakers in this field. This article also discusses the technical challenges associated with HRES as well as the scope of future advances and research on HRES.

An urgent need for alternative sources of energy becomes imminent due to the rapid depletion of fossil fuels, which have been extensively utilized to meet the load demand nowadays
These maximum power point tracking (MPPT) techniques can be primarily classified as tip-speed ratio control (TSR), power-signal feedback (PSF), and hill climb search (HCS) based [65]
The diode clamped, flying capacitor (FC), and cascaded H-bridge (CHB) topologies are the most frequently utilized multilevel inverter (MLI) configurations in grid-interfaced Renewable Energy (RE) systems. These three MLI topologies are considered as the classic MLI topologies, and they are widely employed in industries due to their common advantages, including lower harmonic distortion, higher voltage withstanding capability, FIGURE 29
Summary
An urgent need for alternative sources of energy becomes imminent due to the rapid depletion of fossil fuels, which have been extensively utilized to meet the load demand nowadays. ROY ET AL.: RECENT ADVANCES OF WIND-SOLAR HYBRID RENEWABLE ENERGY SYSTEMS FOR POWER GENERATION: A REVIEW. The hybrid utilization of the PV and WT are one of the most promising technologies among renewable energy sources for satisfying the load demand because they have complementary energy generation profiles. The wind-solar hybrid renewable energy system (HRES) has the ability to suppress the change of single source output power to some extent. The aim is to acquire more stable power output from renewable energy sources, which can be connected with diesel generators, battery banks, ultra-capacitors, or hydrogen production systems. The hybrid wind-solar-diesel energy system is an attractive option, especially when a system is not directly connected to electrical distribution or power grid. 3) HYBRID WIND-SOLAR-BATTERY ENERGY SYSTEM There are several disadvantages, i.e., expensive, bulky, nonenvironmentally friendly, incorporating a diesel engine in the HRES framework. As the generation capacity of diesel generators is limited to a specific range and the solar energy is fluctuating, it is always advisable to include the battery storage to optimize solar energy contribution to the generation of the hybrid system
