energy storage coordination controller

Industry case background:

In the rapid development of the global new energy industry, China has become a leader with its market size and technological iteration. The rise of new energy power stations, especially large-scale energy storage power stations, has triggered an urgent need for efficient and safe management. The number of energy storage inverters (PCS) in energy storage power plants has surged, and traditional AGC/AVC regulation systems are insufficient to cope with fluctuations, prompting the industry to explore more advanced coordinated control solutions, and energy storage coordinated controllers have emerged.

Difficulties in energy storage coordination controller control system:

As the brain of the power station, the energy storage coordination controller centrally controls, optimizes, and coordinates all PCS to improve primary frequency regulation, source grid load interaction, and dynamic reactive voltage response performance. It is necessary to accurately control the charging and discharging characteristics to ensure optimal operation of the power station.

Characteristics of SINSEGYE's solution:

1. Easy-to-use & Strong scalability

The national production distributed coordination controller solution of Zhongke Era adopts a rail type PLC solution, which can be modularized and flexibly configured according to the station topology. It is compact in size, does not occupy space, and is more flexible and economical. In addition, the configuration of Haiguang chips combined with Cambrian graphics cards can optimize performance while also having the advantage of low latency transmission, meeting the requirements of the new national standard for distributed photovoltaic frequency regulation capability and ensuring friendly grid connection of distributed photovoltaics. In addition, this product is also suitable for industrial and commercial energy storage, which can meet the dynamic regulation needs of energy storage systems and provide reliable guarantees for the safe operation of industrial and commercial energy storage.

2. Efficiency improvement

Measurement values of three power testing modules SRC3601: current, voltage, active, reactive, and apparent power, active energy, reactive energy, and apparent energy, power factor, frequency, THD, Harmonics (up to the 63rd harmonic) are measured and calculated entirely within the module, and data is transmitted to the EMS controller via the IEC61850 Goose protocol within 1ms. There are many advantages such as strong real-time performance and customizability. In terms of built-in algorithms, this product innovatively introduces AI assisted electric energy detection algorithms. Compared with traditional frequency zero crossing detection algorithms, it can achieve fast frequency detection with an accuracy of 0.001Hz within 2ms, further improving power regulation efficiency and accuracy.
