The rising demand for renewable energy has recently spurred notable advancements in hybrid energy systems that utilize solar and wind power. The Hybrid Solar Wind Energy System (HSWES) integrates wind turbines with solar energy systems. This research project aims to develop effective modeling and control techniques for a grid-connected HSWES.
This article proposed two hybrid strategies, a hybrid of CNN-ABiLSTM and a CNN-Transformer-MLP model, for the forecast of renewable power production, specifically wind and solar power production.
Among the various renewable resources, hybrid solar and wind energy seems to be promising solutions to provide reliable power supply with improved system efficiency and reduced storage requirements for stand-alone applications.
This study aims to optimize power extraction efficiency and hybrid system integration with electrical grids by applying the Maximum Power Point Tracking (MPPT) technique to solar and wind systems. Combining the control strategy with the optimization algorithm makes our work new and compelling.
Jain, Das made a Geographic Information System (GIS) -based multi-criteria assessment of the solar PV and onshore wind energy potential in India. However, since analysis confined to the spatial scale only was not comprehensive, further analysis on the complementary potential of wind power and PV power at temporal scale was needed.
China has made considerable efforts with respect to hydro- wind-solar complementary development. It has abundant resources of hydropower, wind power, and solar power and shows promising potential for future development.
The successful grid connection of a 54-MW/100-kWp wind-solar complementary power plant in Nan’ao, Guangdong Province, in 2004 was the first wind–solar complementary power generation system officially launched for commercialization in China.
Pumped storage is the most economical and reliable energy storage technology in China at present, and it has vast development prospects under encouraging policies . The installed capacity of pumped storage in China was about 31 million kW in 2020, and it is expected to increase to about 120 million kW by 2030 .
Coordinated control structure of wind power and energy storage. Secondly, the controller parameters of energy storage are evaluated according to the frequency regulation requirements of the system. Finally, the evaluation parameters are sent into the additional controllers to provide reliable frequency support.
Based on the induction factor received from the centralized control system, the turbines capture the kinetic energy from the wind and convert it into electrical energy, where the wake efect impacts the downstream wind turbines by reducing wind speed and generating additional turbulence.
At the same time, the coordinated control problem of multiple voltage and reactive power resources was fully considered. By establishing an optimal voltage control model, precise control of the power station voltage was achieved, significantly improving the coordinated control effect of photovoltaic energy storage power stations.
In order to improve the stability of the wind power and energy storage system, the ESSs adopts the control strategy combining V/f and PQ, which can not only ensure the response to the reference value allocated to the upper layer of ESSs, but also improve the stability of the black-start system.

4 Kazakhstan’s vast and cost-efficient wind energy potential offers a particularly strong foundation for scaling up renewable energy capacity. The country could increase its wind power capacity to 10 gigawatts by 2035, twice as much as the government is currently planning – or even more.
The au thors reported that floating PV systems are less expensive than wind-based floating power u nits. Integrating floating power units enhances p ower generation and reduces operation and mainten ance costs accordingly. The wind energy density is promising away from offsho re, which helps improve the performance of hybrid systems.
The optimized share in power generation is 74% wind power and 26% solar photovoltaic, which results in 8% additional energy generation from renewable s ources. Therefore, it is concluded that floating wind power units have the capability to meet the surplus po wer demands and conv ey additional benefits to integrated power systems. Access
