South Network News "It is expected that in a few months, Hengqin Thermal Power will only take about two seconds to start from` `full black ''. On January 10, Guangdong Power Grid Energy Technology Co., Ltd., as one of the joint contractors, officially launched the preliminary work of the 20 MWh battery energy storage system project of SPIC Zhuhai Hengqin Thermal Power Co., Ltd., responsible for the integration and integration of the energy storage project system, Network test, black start, etc. The project is expected to be put into production in mid-2019, and it is the first project in the world to use an energy storage system to achieve the black start of F-class gas turbines and the first domestic gas turbine energy storage frequency modulation project. The energy storage system can not only assist the unit to perform grid frequency adjustment, participate in the electricity spot market, improve the unit's operation stability, but also realize the unit's black start, which will build another line of defense to ensure power supply to Macao.

  After the super typhoon "Tiange" in 2017, Guangdong and Macao formed a consensus on improving the disaster prevention and mitigation capabilities of power supply projects-"strengthening Zhuhai's local support for power supply construction, with isolated grid operation capability and black start function".

  Hengqin Thermal Power Co., Ltd. is an important power source for power supply to Australia. With the assistance of Guangdong Power Grid Energy Technology Co., Ltd., it completed the FCB (Unit Quick Load Reduction) function transformation and test in June 2018, and officially has the ability to operate independently. Realizing a black start on this basis can greatly improve the reliability of power supply to Australia.

  "Traditional black-start is mostly implemented with diesel generators, but it is limited to small and medium-sized gas turbines of class E and below. If it is used for black-start of class F gas turbines, it will face high maintenance costs, low daily utilization and increased risks. Source and other issues. What's more critical is that it starts slowly and takes about 30 seconds with full load, while the energy storage system responds quickly and can take full load in about two seconds. Jia introduced, "In addition to achieving a black start, the energy storage system can also assist the unit to perform grid frequency regulation, high stability, sustainable revenue generation, no pollution, no noise, and can be described as environmentally friendly and economical."

  In order to optimize the efficiency of the energy storage system, the company also plans to use an independently developed "energy storage and unit load distribution device" for the Hengqin Thermal Power Project, using scientific algorithms, automatic calculation, research and judgment, and reasonable frequency adjustment to reduce unit wear , Reduce energy consumption, improve unit operation safety and reliability.

 In recent years, Guangdong Power Grid Energy Technology Co., Ltd. is actively committed to the research and development and industrialization of energy storage technology. In addition to frequency modulation of the power grid using energy storage technology, it has also applied a series of products such as battery management systems, energy management systems, and energy storage converters. In substations, distribution stations, and even information rooms, it provides overall solutions for various business areas in the power market and promotes the transformation of China Southern Power Grid to an energy industry value chain integrator.
