With the introduction of a series of supporting policies and the gradual improvement of the market mechanism, energy storage technology has also risen, and it has made its debut in the field of power peak and frequency modulation. EMS越来越受到大家的关注与期待,德联软件在储能EMS技术方面已经趋于成熟,且适用于多种能源的多种应用场景。 The corresponding EMS has received more and more attention and expectation from everyone. Taklink has matured in energy storage EMS technology and is suitable for multiple application scenarios with multiple energy sources.

 

1】 国内某多能互补项目 [Case 1] A domestic multi-energy complementary project

Combining energy storage with wind power, photovoltaics, light and heat, effectively solving the imbalance of power output during peak and low power consumption periods, improving energy efficiency, optimizing the quality of new energy power, enhancing the stability of power output, and increasing power The system's ability to absorb intermittent renewable energy sources such as wind power and photovoltaic power generation, and its comprehensive benefits.

700 兆瓦,其中储能 50 兆瓦 /100 兆瓦时,风电 400 兆瓦,光伏 200 兆瓦,光热 50 兆瓦。 The total installed capacity of the project is 700 MW, including 50 MW / 100 MW of energy storage , 400 MW of wind power , 200 MW of photovoltaic , and 50 MW of light and heat .

The introduction of multi-energy complementation in energy storage effectively reduces the peak pressure of the power grid and reduces the proportion of power cuts caused by abandoning wind and light.

The project's access to the electricity sales bidding platform promoted the reform of the power system and increased the range of options for power consumers.

3】重庆空港-充储放一体化监控系统 [Case 3] Chongqing Airport-Charge, Storage and Discharge Integrated Monitoring System

Project background :

The commissioning of charging stations has brought the following problems to the urban distribution network:

1) The peak charging power is high, causing a sudden voltage drop and affecting grid safety.

2) There is a large difference between the average operating power and the peak power of the charging station. The utilization efficiency of transmission and distribution facilities and charging station equipment is very low, resulting in high power supply costs.

3) Buses operate mainly during the day, and valley electricity usage is extremely low.

Contribution of storage strategy to charging station :

1) The energy storage system can effectively reduce the rated power level of the distribution transformer.

2) The energy storage system can realize the shift from the trough load to the peak load and the flat peak load to the peak load.

3) The energy storage system can effectively reduce the impact of the steep rise and fall of charging power on the power grid and calm the power fluctuation rate.

4) Energy storage systems can achieve peak-valley arbitrage.
