The average annual increase in electricity demand is 8.5%. Savings give priority to equipment development (1)

During the “11th Five-Year Plan” period, China’s power industry’s ability to support economic and social development has been significantly enhanced, its power supply structure and layout have been further optimized, and the level of power technology equipment and capabilities for independent innovation have improved significantly.

At the same time, there are still some deep-seated problems in the development of the power industry. The unified planning of the power industry needs to be strengthened urgently. The scientific and reasonable electricity pricing mechanism has not yet been formed. The sustainable development capacity of power companies is weak, and the proportion of existing green power generation is far from the future development goals. The ability of resource allocation cannot meet the needs of economic and social development, the capacity for scientific and technological innovation needs to be improved, and market-oriented reform needs to be deepened.

According to the “Twelfth Five-Year Plan” research report issued by the China Electricity Council, during the “Twelfth Five-Year Plan” period, the development direction of China’s power industry will be driven by scientific and technological innovation, and will be based on the transformation of power development methods. Adhere to saving priority, give priority to the development of hydropower, optimize the development of coal-fired electricity, vigorously develop nuclear power, actively promote new energy generation, moderately develop centralized natural gas power generation, develop distributed generation according to local conditions, accelerate the construction of a strong smart grid, drive the development of the equipment industry, and promote green harmony development of.

About trillion yuan, about 3 million jobs are provided each year.

3. Giving priority to the development of hydropower and optimizing the development of coal-fired power The coal-fired power generating unit of China’s coal-fired power station has the lowest cost of electricity generation; the cost of nuclear power generation is less than that of the coal-fired power generation unit of the load center; currently, the cost of generating electricity from hydropower is relatively low, and hydropower is considered to protect the ecological environment. The increase in investment in resettlement and other aspects and the increase in transmission costs, etc., the cost of utilities is close to or slightly higher than the cost of coal and electricity in the load center; the cost of generating electricity from wind power, solar energy, biomass, and natural gas is much higher than coal, nuclear and hydropower. In order to co-ordinate the next decade and long-term development strategy, the power supply development must adhere to the principle of giving priority to the development of hydropower, optimizing the development of coal-fired power, vigorously developing nuclear power, actively promoting new energy generation, moderately developing natural gas for centralized power generation, and developing distributed generation according to local conditions.

Hydropower: Promote the integrated development and development of hydropower basin cascades: promote integrated hydropower basin cascade development. We will actively promote the construction of large-scale hydropower stations in the southwest region, develop local and small rivers' hydropower resources according to local conditions, and implement the combination of large, medium and small development. Actively develop hydropower basin planning and preparatory work in Tibet to ensure the sustainable development of hydropower.

Expand the scope of resource allocation. Large-scale hydropower bases meet the electricity demand of the region, and they are transported to the East and Central regions where the market demand is large and the electricity price is high. This ensures the efficient use of hydropower resources. Promote the development of hydropower resources in neighboring countries and transmit electricity to China.

Scientific planning and construction of pumped storage power stations. Strengthen the overall optimization and unified planning of power supply, increase the development of pumped water storage, increase the economical efficiency and flexibility of power system operation, and promote the reasonable consumption of renewable energy power generation.

Development priorities: Continue to accelerate the development of seven hydropower bases in the upper reaches of the Yangtze River, Wujiang River, Hongshui River in Nanpanjiang River, the middle and lower reaches of the Yellow River, the North Main Stream, Xiangxi, Fujian, Zhejiang, Jiangxi, and Northeast China. The development is completed as soon as possible. We will focus on the development of six hydropower bases in the western region, including the Jinsha River, Yalong River, Dadu River, Lancang River, Nu River, and the upper reaches of the Yellow River. Promote the development of hydropower development in Tibet, such as the Brahmaputra. Development of hydropower in Myanmar and transmission of electricity to China.

The development target of conventional hydropower: During the “12th Five-Year Plan” period, the national scale of hydropower starts will be 120 million kilowatts, and the production will be about 87.50 million kilowatts. In 2015, the national average installed capacity of hydropower is estimated to be about 284 million kilowatts. The national level of hydropower development reached 52% (calculated according to technologically exploitable capacity), of which hydropower was basically developed in the eastern and central regions, and 43% in the west. During the “Thirteenth Five-Year Plan” period, the scale of hydropower production in the country is about 46 million kilowatts. By 2020, the national hydropower capacity will be about 330 million kilowatts. The level of hydropower development in the country is 61%, of which the hydropower development in the west is 53%. In 2030, it is estimated that the installed capacity of hydropower in the country will be 450 million kilowatts, which exceeds the economically exploitable capacity. With the exception of Tibet, the nation’s hydropower basic development is completed.

Pumped storage development goals: To strengthen unified planning, accelerate the development of storage power stations, improve the performance of power system peaking and frequency regulation, and meet the need for large-scale development of new energy power generation. Strengthen the preliminary work of pumped storage power stations and do a good job of project reserves. Establish and improve the grid price mechanism and ancillary service pricing mechanism to ensure reasonable investment returns for the construction of storage power stations.

It is planned that the planned installed capacity of the storage power station in 2015 will be about 41 million kilowatts, and about 60 million kilowatts in 2020.

Solar Charge Controller

Bosin solar charge controller is a vital component in a solar power system that regulates the flow of electricity from the solar panels to the batteries. It plays a crucial role in protecting the batteries from overcharging and ensuring their longevity.The primary function of a solar charge controller is to prevent overcharging of batteries. When the solar panels generate more electricity than the batteries can handle, the charge controller automatically regulates the charging process to avoid damage to the batteries. It monitors the battery voltage and adjusts the charging current accordingly, preventing overcharging and extending the battery life.

Another important role of a solar charge controller is to prevent reverse current flow. During the night or in low-light conditions, the solar panels do not generate electricity, and there is a possibility of reverse current flow from the batteries to the panels. The charge controller prevents this reverse current flow, protecting the panels from damage.

Furthermore, our Bosin solar charge controller helps optimize the charging process by employing various charging algorithms. It ensures that the batteries receive the appropriate voltage and current levels during different stages of charging, such as bulk charging, absorption charging, and float charging. This optimization enhances the charging efficiency and maximizes the battery's capacity.
