Promote solar and wind power generation system technology to become the main energy of the future

Both solar photovoltaic power generation and wind power generation technology have made great progress, but there is still a long way to go before solar and wind energy systems can truly become important energy sources that the world can rely on. In addition to the advantages of abundant resources, cleanliness, and environmental friendliness, hybrid wind and solar power systems also have disadvantages such as low energy density and certain intermittent and fluctuating properties.

Technical aspects of solar photovoltaic power generation system
Solar cell technology and system equipment will develop in the direction of high energy efficiency, low cost, long life and intelligent technology. The key R&D plan should continue to support the R&D of high-efficiency crystalline silicon solar cells and thin-film cells for industrialization, as well as key technologies for new solar cells and industrial R&D; support for technological innovation and level improvement of photovoltaic systems and balance components; Research and test platform construction.

wind power technology
In the future, the single-unit capacity of wind turbines will continue to increase, and the flexible blade technology of large-scale wind turbines and the core control technology of the units need to be developed urgently; the doubly-fed asynchronous power generation technology will still occupy the mainstream position, and the direct-drive and full-power converter technology will be used in larger-scale wind power generation. The proportion of applications on wind turbines is increasing, and it is expected to become the mainstream technology in the future; various speed-increasing full-power converter wind turbines will be applied; wind power equipment research and development in low wind speed areas will make progress; the technical level of wind farm construction and operation will be Increasingly; offshore wind power technology will become an important development direction.

Hybrid energy storage system technology
Efforts should be made to study large-capacity and high-power energy storage technologies, improve efficiency, and achieve leaps in scale, lifespan and cost of energy storage technologies. In the aspects of large-scale access to renewable energy, peak regulation and efficiency improvement of traditional power systems and regional energy supply, complete system solutions and demonstration projects with completely independent intellectual property rights and instructive significance for international energy storage technology and industrial development, forming a comprehensive A complete set of energy storage technology research and development system for technical research, technology demonstration and engineering application.

Multi-energy complementary and distributed energy technology
The future development direction is: the complementary utilization of multiple renewable energy sources and their comprehensive and efficient utilization with conventional energy forms; the research on a series of key technologies for high-proportion consumption and delivery of renewable energy sources, and the establishment of renewable energy sources for different climates and different energy needs. Demonstration of renewable energy supply systems, as well as research and demonstration of renewable energy-based energy systems.
