hybrid wind-solar

According to a new report by the Institute for Energy Economics and Financial Analysis (Ieefa) and JMK Research, the Solar Energy Corporation of India (SECI) has so far tendered a total of 12,860 MW hybrid capacity.

The Australian Capital Territory (ACT) has awarded a power purchase agreement in its fifth renewables reverse auction. The deal relates to a portion of a project consisting of 1.2 GW of wind, 600 MW of solar, and 900 MW/1,800 MWh of battery storage.

Longyuan Power has signed a deal to build a 2 GW hybrid wind-solar-storage project in Inner Mongolia. JA Solar and Sungrow, meanwhile, said that they have supplied PV modules and inverters for a 133 MW solar-wind project in South Korea.

A study from the Lappeenranta University of Technology states a deeper complementarity between solar and wind generation may favor renewables deployment reducing the need for stronger developments in storage technology. Combining solar with wind more widely could also reduce the need for ramping and improve the reliability of energy supply, say the researchers.

Almost 10 GW of hybrid generation capacity is already under implementation despite the nation having only 100 MW of combined wind and PV projects at present, according to analyst Crisil.

An international research team is proposing a fuzzy logic approach for optimal site selection of large-scale wind, solar and hybrid wind-solar power projects. The new methodology is based on criterial components for energy optimization through climatological, topographic and human factors.

A researcher has proposed a new approach to apply maximum power point tracking techniques to optimize electricity production in wind-solar power projects. The permanent magnetic synchronous generator hybrid model used in the study is based on a multi-input rectifier stage which is said to be able to eradicate current harmonics and eliminate the need for extra input filters.

The Smart Grid Station wind-PV facility also incorporates a 500 kWh lithium-ion battery storage system, around 2,000 internet of things-derived sensors and smart meters. The plant was installed by the Dubai Electricity and Water Authority and Korean utility KEPCO.

India has unveiled a national wind-solar hybrid policy that provides a framework for promotion of large grid connected wind-solar PV systems for optimal and efficient utilization of transmission infrastructure and land, reducing the variability in renewable power generation and thus achieving better grid stability.

The assessment was conducted by Brazil’s energy agency Empresa de Pesquisa Energética (EPE). These projects are expected to be particularly suitable to regions with a low degree of grid integration.
