Backup power supply

Lead acid batteries are widely used in the field of backup power sources, such as UPS, security, data centers, military, etc. When equipment cannot be connected to mains power, lead acid batteries will provide temporary power supply to the equipment to protect it from data loss caused by power outages.

Solar system

In the long run, renewable energy will be the main source of energy for humanity in the future. Therefore, most developed countries and some developing countries in the world attach great importance to the important role of renewable energy in future energy supply. Among new renewable energy sources, photovoltaic and wind power are the fastest growing, and countries around the world have made the commercial development and utilization of solar photovoltaic power an important development direction. It is expected that solar power generation will play an important role in the world's electricity supply by 2030, reaching over 10%, with renewable energy accounting for 30% of the total energy structure; By 2050, solar power generation will account for 20% of total energy consumption, with renewable energy accounting for over 50%. By the end of this century, solar power generation will play a leading role in the energy structure.

What is CIGS battery also given here? From the table above, it can be seen that solar cells are classified according to different materials, and can be sorted according to the degree of photovoltaic application. There are polycrystalline silicon cells, monocrystalline silicon cells, CdTe cells, amorphous silicon cells, CIGS cells, and other solar cells. Overall, CIGS cells are a type of solar cell, with the use of copper indium gallium selenide (CIGS) material as the cell layer material, forming a PN junction for solar energy to absorb sunlight and generate electricity. This type of solar cell has gained market recognition due to its low cost and high conversion efficiency, and its share in all solar cells is increasing. It is also a hot investment topic in solar cells at present.

Based on the current technological development status, it is predicted that high conversion crystalline silicon batteries, thin film batteries, and high concentration multi junction batteries will be the development trend. The prospects of these two technological routes, crystalline silicon batteries and amorphous silicon thin film batteries, are the most optimistic. In the construction of large-scale power plants, high concentration multi junction batteries with potential for improving conversion efficiency still provide an efficient and environmentally friendly solution; Meanwhile, the competitiveness of CPV in grid connected power generation cannot be ignored (in addition to low cost, this technology route can complement biomass and natural gas power generation to achieve continuous and stable power supply). In addition, hybrid power generation forms such as photovoltaic and solar thermal hybrid power generation, wind solar complementary power generation, etc. are a good choice for grid connected power generation systems because they can compensate for the unstable output power caused by solar radiation over time and weather changes.

Data Center Network

The current data center infrastructure is facing challenges from the rapid growth of cloud computing and mobile internet data usage, and many data centers around the world are facing significant changes to keep up with current needs and meet future network development with higher bandwidth requirements.

The trend of modern data centers has gradually shifted from traditional three-layer networks to more simplified and suitable two-layer networks for cloud computing applications, known as leaf backbone networks, which have greatly improved flexibility and efficiency. Another significant change is the improvement of data speed between networks, with host to host connections upgrading from 1G to 10G, and switch to switch connections starting to upgrade to 40G and 100G.

Accompanied by these changes are the main technical challenges faced by relevant optical module, component, and chip suppliers. Avago Technologies has already addressed these technical challenges and brought highly differentiated solutions to the market that can meet the growing demands of modern data centers.

Wind power generation system

With the depletion of fossil fuels and the aggravation of environmental pollution, the development of renewable energy has received extreme attention. Wind power generation, as the most mature power generation technology in renewable energy generation, has rapidly developed in recent years with strong government support.

In just ten years, China's proportion of wind power generation in the world's wind power has increased from 1.66% in 2004 to 27%, and the total installed capacity of wind power has jumped to the top in the world. In 2013, wind power accounted for 2.6% of the country's 5.26 trillion kilowatt hours of electricity generation, surpassing nuclear power generation. In less than 10 years, wind power generation has surpassed nuclear power, which has been developing for 40 years, and has risen to the third largest energy source in China. The Energy Research Institute of the National Development and Reform Commission predicts that by 2050, the installed capacity of wind power will reach 1 billion kilowatts, providing 17% of domestic electricity.

The rapid development of wind power has also exposed a series of management problems. Based on summarizing the problems of wind power management, this article proposes an improvement plan for wind farm management, namely the research and development of intelligent management and centralized control systems.
