Establishing a new power system is the key



All forces in the new energy vehicle industry chain , They are giving full play to their respective advantages , Power battery energy storage project 、 Optical storage and charging integrated charging station and other forms expand to the field of energy storage . Behind this , On the one hand is “ Double carbon ” The power of the goal helps push , On the other hand, it is the strategic consideration of the enterprise for its own long-term development .


Data from the National Bureau of statistics shows that ,2020 In the annual carbon emission distribution , Power generation alone accounts for... Of the total 51%. therefore , It is very important to solve the problem of carbon emission at the power supply end . however , If we want to replace the traditional thermal power generation , Regardless of water or electricity 、 Wind power , Or photovoltaic power generation and other power generation methods using renewable energy , The first thing to be solved is the configuration of energy storage system .


before , in the light of “ How to achieve carbon peak 、 Formulate and implement relevant safeguard measures for the medium and long-term goal of carbon neutralization ” problem , Yuan Da, director of the Political Research Office of the national development and Reform Commission, said , Vigorously adjusting the energy structure is one of the measures . among , Including promoting clean and low-carbon development of the energy system , Steadily promote the development of hydropower , Safe development of nuclear power , Accelerate the development of photovoltaic and wind power , Accelerate the construction of a new power system to adapt to the development of a high proportion of renewable energy .


The reporter learned that , Build a new power system with new energy as the main body , Need to be in the production of electric energy 、 send 、 Increase investment with the whole chain . From the power side , In order to solve the randomness caused by the installation of new energy 、 Volatility issues , We must accelerate the construction of energy storage projects ; From the grid side , Ensure reliable power supply 、 Run security , The peak load regulation of power system needs to be greatly improved 、 Frequency modulation, voltage regulation and other capabilities, as well as configuration of relevant technical equipment ; From the user side , The government encourages the diversified development of user energy storage , Need distributed energy storage facilities and Technology .


Miao gen, chief marketing officer of Jingke energy It means , Jointly promoted with GuoXuan high tech “ Photovoltaic + Energy storage ” programme , It can solve the intermittent pain points of photovoltaic , Make it a continuous power grid 、 Security 、 reliable 、 Efficient and friendly power supply .


On the power side 、 In the process of connecting the grid side and the user side , The charging pile is working . Huang Shengxuan, chief executive of Beijing Taikang investment, once pointed out ,“ Double carbon ” Goal driven energy change is a long-term strategic trend , The new energy charging industry is to create “ New infrastructure ” Important foundation .


at present , Optical storage and charging integrated charging stations are being put into operation all over the country .
