Liaoning conquers battery energy storage technology -Lithium - Ion Battery Equipment

At the 18th National Congress of the Communist Party of China (CPC), it was clearly proposed to vigorously promote the construction of ecological civilization and incorporate it into the "five in one" overall layout of socialism with Chinese characteristics. The CPC Liaoning Provincial Committee and the provincial government have implemented the idea of ecological civilization, deeply implemented the project of "blue sky, clear water, pure land, green mountains and rural environmental protection", and a new picture of "beautiful Liaoning" is slowly unfolding. State Grid Liaoning Electric Power Co., Ltd., as a responsible central enterprise, has thoroughly studied and implemented the spirit of the 18th and 19th National Congress of the Communist Party of China, firmly established the "Four Consciousness", actively connected with the revitalization strategy of Liaoning's old industrial base, firmly grasped the direction of scientific and technological progress, actively promoted the "Blue Sky Project" and "Electrified Liaoning" work process, and strengthened collaborative innovation to tackle key problems around clean energy consumption of Liaoning Power Grid, We have actively built and put into operation a number of scientific and technological innovation demonstration projects, constantly improved the ability of the power grid to accept clean energy, and promoted the healthy development of Liaoning's ecology.(Lithium - Ion Battery Equipment)

Solve the problem of clean energy consumption

Liaoning Power Grid is the load center of Northeast Power Grid, with the installed power capacity accounting for 35% of Northeast Power Grid and the electricity consumption accounting for 50% of Northeast China. From 2008 to 2012, wind power in Liaoning Province increased explosively, with an average annual growth rate of more than 100%. Influenced by factors such as the lower than expected load rise, the minimum thermal power operation mode, especially the new heat supply units, and the continuous operation of nuclear power, in 2010, Liaoning power grid began to have the problem of wind abandonment. The wind power consumption capacity continued to decline, and the problem of wind abandonment became more obvious. By 2015, the wind abandonment rate reached 14.60%, and the contradiction of wind power consumption was prominent.

The problem of absorbing clean energy is emerging, what measures should be taken? How to solve the problem? State Grid Liaoning Electric Power began to embark on their road of scientific and technological innovation... In 2011, Liaoning Electric Power took the lead in undertaking the 863 Program "Research and Development of Key Technologies for Improving Intermittent Power Supply Access Capacity of Energy Storage System", studied and proposed a wide area coordinated control method for energy storage power plants, and built the largest Vanadium Liquid Flow Energy Storage Power Station in the world at that time. The completion and operation of the energy storage power station has improved the utilization efficiency of intermittent clean energy, and realized the functions of peak shaving and valley filling, tracking the wind power generation plan, etc. At the same time, Liaoning Power Grid Provincial Dispatch has developed a multi-source coordinated control system for wind, fire and water storage for the first time, realizing the online dispatching and operation of wind power energy storage system. On the premise of ensuring the security of the grid, the grid can accept the wind power output to the maximum capacity. All these have created positive conditions for Liaoning to absorb clean energy in a high proportion. In view of the large installed capacity of wind power in the power grid, the difficulty in clean energy consumption caused by the decline of peak shaving capacity during winter heating, and the phenomenon of "abandoning wind" and "abandoning nuclear power", Liaoning Electric Power strengthened collaborative innovation from the technical direction of grid battery energy storage, electric heat storage, and deep peak shaving of generator units, and carried out a series of scientific research and technological breakthroughs.

State Grid Liaoning Electric Power spared no effort to absorb clean energy. In Liaoning, the concept of "green water and green mountains are golden mountains and silver mountains" has been deeply rooted in the hearts of the people. The energy consumption structure is undergoing positive changes. The top-level design of ecological civilization and the construction of the system are accelerating.
