For the certain period of time, coal power will still be the heavyweight of power supply.Sugar babyTo be constructed, it will still need to exist at a certain scale of capacity for a longer period of time.

In September 2020, General Jinping proposed China’s “carbon peak” and carbon neutrality targets, coal-electricity with a machine capacity of more than 1 billion kilowatts has become an embarrassing existence in the Chinese dynamic circle. Many people believe that as the carbon reduction potential of coal-electricity is gradually reaching the bottom, the final addition of coal-electricity will be the key to carbonization peak and carbon neutrality in China’s power industry.
After the fog in 2013, coal and electricity have always been under blame in the domestic market, and now it has reached the edge of “death”. However, the life span of coal and electricity may not be as good as the isolated perspective of carbon neutrality target, but also from the perspective of the large environment and format of the entire power system.
When we have a broad perspective, the conclusions can be different: not only will the coal and electricity not only die, but will even play the role of the actor in the new future power system.
The impact of large-scale and online light and online light
In the context of carbon neutrality, the industry expects that the annual growth rate of new style and optical devices will be 50 million kw and 70 million kw in the next ten years. In 2030, the new dynamic devices will exceed 1.2 billion kw, reaching more than 1.7 billion kw, and it is widely expected to reach 1.2 billion kw by 2025, with a growth rate significantly exceeding the 13th Five-Year Plan period. During the 13th Five-Year Plan period, the average annual increase in wind turbines was about 30 million kw (exhausted in 2020, and the new engines exceeded 70 million kw that year), and the average annual increase in photovoltaic engines was about 50 million kw. Even for third-party institutions, most of the annual new photosynthetics tests in the photosynthesis project have increased by more than 100 million kw.
The power system is a non-linear time-changing energy balance system that exceeds the scale. It must always maintain balance. The production organization form is “source load”. Electricity is the active adjustment set, and the negative load is the passive unchanging set. The active adjustment is the active adjustment, and the negative load operation is followed by a precise and controllable power generation system. It is equipped with a basic and detectable power supply system.s://philippines-sugar.net/”>Escort Manila‘s system, through the rotation adjustment during the actual operation, the power system can realize the safe and reliable operation.
New powers mainly based on wind and light generation cannot be as good as “source load” (wind and light are not controlled), or only It can “source load” (discard wind and light, reduce output); at the same time, after a large number of distributed new power connections are connected on the power side, the accuracy of negative load prediction also drops significantly. As a result, the large scale connection of new powers will have a grand impact on traditional power networksSugar daddy. Before the power side energy has fully developed, the wind and optical power generation systems have no peak frequency, rotation and no Escort peak frequency, rotation and no Escort Manila‘s ability to replenish. Random atmosphere conditions make the machine’s efforts change at the same time, which makes the network structure more impactful, so that the network needs to be constructed in a corresponding rotation and replenishment point for wind and optical power generation systems. “To solve the peak frequency and effective control and adjustment of the voltage, other common power sources are required to supply active power to replenishment adjustment, and Sugar daddy guarantees the power supply of the network to a continuous, stable and reliable load.
In theory, the power generation capacity added by the wind and light entering the network is not as effective as reducing the common power generation units owned by the power system. Therefore, from a certain meaning, the existence of wind and light generation is equivalent to adding an “indeterministic burden” to the Internet.
The wind and optical power generation are connected to the power network in a large scale. Escort faces the future of “two highs” (high proportional cleaning power, high proportional power electronic system), and not only needs to adjust the specific gravity of new power generation (disinfection), but also ensure the safety of power use. It is necessary to build a new power system with new power as the main body. New power systems with new power as the main body means that wind and light generation will be the main body of power systems without Sugar daddy. Coal and electricity will be reduced from the main force to assist in power, but it must also bear the responsibility of “pressure stone” for power supply. Coal power positioned as aids in power, to ensure network safety, the total capacity of the surface machine cannot be as low as possible, but the operational efficiency (applicable hours) The embarrassing situation that cannot be as high as possible!
Coal and electric power is the “trump card” of Internet safety
The wave of wind and optical power fluctuation changes randomly with the weather conditions, and is much higher than the normal negative load change of Internet. Therefore, the adjustable capacity prepared for wind and light generation cannot be easily achieved by relying on temporary start and shutdown, but must be kept in the rotation preparation state. As a result, the larger the capacity of the wind and light generator, the larger the capacity of the rotation is. Therefore, when the wind and light power generation ratio are connected to the power network, a large number of flexible and adjustable power sources, namely, flexible power sources. In theory, traditional forces can be used as active power sources because they are all adjustable and controllable. Such as hydroelectric (including pumping storage), gas, electric Manila escort tank (electrochemical energy storage), and coal electricity. In terms of water and electricity, the capacity of water and electricity installations in my country is 37 million kw, of which 30 million kw of the pumping storage station is 30 million kw. Due to double pressure from resources and environment, the space for water and electricity development is no longer large. The adjustment of the hydroelectric factory (including pumping and storage) is stronger. The capacity is large and the opening/stop adjustment of the machine is a more fantastic peak-pressing power supply. However, the layout of the water and electricity is subject to the constraints of natural resources and is limited in both address selection and capacity. Adding the water and electricity cycle (the dry period) will make it sometimes have the need for peaking. Today, the 30 million kw machine capacity of our pumping and storage station clearly lacks the efficiency of fully bearing the flexible power supply.
Air power is extremely advantageous in peak adjustment and ultra-low emissions. The gas-electric power stop rate is fast, and the large machine can hold it for 1 hour when it is activated until it has a lot of load. It can quickly respond to network demand and provide reliable peak support for the network; the nitrogen oxide emissions are small, and the S02 and smoke emission base is zero, which is clean and environmentally friendly compared with coal-to-electricity. However, due to China’s “rich in coal, oil and gas” resource income, the higher gas price and safe supply are not fully guaranteed, making my country’s gas electric machines more unlimited. By the end of 2020, my country’s gas electric machines reached 100 million kw, but only account for 4.5% of the total engine capacity; otherwise, summer is often the natural gas air, and the demand for ensuring the growth will also restrain the output of gas electric peaks.
Today, I would like to see the energy-energy application system, especially the electrochemical (battery) energy-energy, and thePulse the energy to absorb energy. The battery can control the output power with power electronics, and the response should be very agile. It is very suitable for the power system’s modulation frequency. The frequency consequence is 1.7 times that of the hydroelectric motor, which is far better than that of the coal motor. In the long run, energy storage or energy (hygrogen can be seen as a kind of energy storage) plus smart power systems are the ultimate solution to the carbon neutrality of the power system. However, in the near certain period, the energy storage cannot fully implement peak performance.
First, the capacity of the energy storage system, which is mainly based on the steel battery, is unlimited. The capacity is set to 10% of the installation capacity, and the charging (discharging) time is 2 hours. For power systems, such a setup installation is useful in a short time perio TC:
