With the increase of new energy penetration, fire storage joint commissioning has gradually become one of the main means of power frequency modulation market. So what advantages does the first mock exam have?
At present, the demand for flexible resources in the power system is gradually increasing. By installing energy storage, the thermal power plant can improve the regulation performance of the thermal power plant, increase the flexible regulation resources of the power system in the short term, ensure the safe and stable operation of the power grid, and promote the power grid to improve the consumption capacity of new energy.
Specifically, "Joint commissioning of thermal power and energy storage" means that thermal power and energy storage jointly contribute to the power grid frequency regulation command. Thermal power units are not flexible enough. From the index of climbing speed, the climbing speed of coal-fired power units is generally only 2% - 5% / min, which is much lower than 20% - 100% of gas-fired units and 50% - 100% of hydropower. Through the joint frequency regulation of thermal power and energy storage, the advantages of rapid response of energy storage can be brought into play, the response speed of thermal power units can be improved technically, and the response of thermal power to the power system can be improved The response capability of the system has been regarded as an important way for the flexibility transformation of thermal power units.
