  • Patent number: 12136818
    Abstract: A thermal power unit-flywheel energy storage cooperative frequency regulation control method and system is provided, which belongs to the technical field of a power grid. First, a real-time output increment of a thermal power unit is predicted, then a real-time frequency regulation power instruction of a flywheel energy storage system is determined based on the predicted real-time output increment of the thermal power unit, and finally the frequency regulation power instruction of the thermal power unit is determined by a difference adjustment coefficient of a governor and a grid frequency deviation. The thermal power unit and flywheel energy storage system is cooperatively controlled by frequency regulation based on the real-time output increment predicted value of the unit, which realizes self-adaptive adjustment of output of the flywheel energy storage system under dynamic working conditions, and improves the grid frequency stability and operation safety of the thermal power unit.

  • Patent number: 10208088
    Abstract: The present invention discloses the applications of a low molecular polypeptide ZY4 in preparing drugs for anti-acnes, anti-infection, anti-cancer and cosmetics. The low molecular polypeptide ZY4 comprises 17 amino acid residues, with a molecular weight of 2374.0 Da, an isoelectric point of 10.74, and an amino acid sequence of SEQ ID NO:1. The low molecular polypeptide ZY4 in the invention is artificially synthesized, with the advantages of small molecular weight and convenient artificial synthesis. The experiments have showed that the polypeptide ZY4 has obvious antibacterial effect and has significant therapeutic effect on acnes. The polypeptides can inhibit the growth of tumor cells and kill the tumor cells. The low molecular polypeptide ZY4 can be used in the preparation of medicaments or cosmetics having the effect of anti-infective, anti-tumor or anti-acne.
