On September 30th, the fourth phase of knowledge sharing activities of Hanas New Energy Division was held as scheduled, with Wang Yi, director of the operation department, as the lecturer, and the training topics was "New Power System Construction - Energy Storage", come and learn with me!
The concept of a new type of power system：
The new power system is a power system that takes the realization of carbon peak carbon neutrality, implements the new development concept, builds a new development pattern, promotes high-quality development, ensures energy and power security as the basic premise, meets the power demand of economic and social development as the primary goal, maximizes the consumption of new energy as the main task, takes the strong smart grid as the hub platform, and takes the interaction and multi-energy complementarity of source, network, load, storage and multi-energy as the support, and has the basic characteristics of clean and low-carbon, safe and controllable, flexible and efficient, intelligent and friendly, and open interaction。
What is Energy Storage：
The significance of power generation and Energy Storage：
With the upgrading of the energy system Solar, ocean energy, wind energy, geothermal energy and other renewable energy sources began to be widely used, but the sun will set, the wind "temper" is elusive, solar energy, wind energy is only produced at a specific time, light, wind and other unstable natural conditions lead to unstable output power, can not meet the requirements of the power grid, and energy storage, can play a role in regulating the grid load curve, stabilizing the power grid, increasing renewable energy consumption capacity.
The significance of grid Energy Storage：
Energy storage and power grid cooperation, greatly improve the traditional power balance of the power grid planning and dispatching methods, can comprehensively improve the capacity of clean energy consumption, Energy Storage can participate in the power grid peak regulation frequency regulation, harmonic suppression and other power auxiliary services, can effectively increase the power supply reliability of the power grid, so that it in peak regulation, frequency regulation, mitigation of congestion, substitution and delay transmission and distribution investment, voltage support and reactive power control, fault emergency standby and other aspects play an important role.
The significance of user-side Energy Storage：
User-side Energy Storage is mainly to solve the contradiction of "the grid has electricity, but there are equipment differences at all levels of the grid, resulting in the peak period of electric energy can not be safely delivered to the user".
For industrial and commercial enterprises that implement peak-valley time-of-use electricity prices, Energy Storage systems can allow enterprises to store electricity when the valley is electricity and power supply when peaking electricity, so that they can obtain benefits through the difference between peaks and valleys electricity prices once again.
The Energy Storage system can also double-use as a backup power source to achieve power capacity increase. For example, national defense, hospitals, factories, communication base stations, charging facilities, etc., which require uninterrupted power consumption, can use Energy Storage systems as backup power sources.
The type of power storage：
Six types of Energy Storage technologies：
Pumped Energy Storage
Lithium-ion battery Energy Storage
Sodium-ion batteryEnergy Storage
Flow battery Energy Storage
Lead-carbon battery Energy Storage
Compressed air Energy Storage
