Abstract: A method for automatic adjustment of a power grid operation mode based on reinforcement learning is provided. An expert system for automatic adjustment is designed, which relies on the control sequence of thermal power units, enabling automatic decision-making for power grid operation mode adjustment. A sensitivity matrix is extracted from the historical operating data of the power grid, from which a foundational thermal power unit control sequence is derived. An overload control strategy for lines within the expert system is devised. A reinforcement learning model optimizes the thermal power unit control sequence, which refines the foundational thermal power unit control sequence and provides the expert system with the optimized control sequence for automatic decision-making in power grid operation mode adjustment. This method offers a solution to balancing and absorption challenges brought about by fluctuations on both the supply and demand sides in high-proportion renewable energy power systems.

Abstract: Disclosed are an oxazine compound and an application thereof. The oxazine compound has a structure of a general formula F. The oxazine compound described in the disclosure is a photo/acoustic dynamic active organic molecule with near-infrared absorption-emission function as well as photosensitivity and acoustic sensitivity. Maximum absorption and emission wavelengths of the compound are both greater than 660 nanometers, and a triplet-state conversion rate of the compound is high; and under illumination or ultrasound, the compound can produce reactive oxygen species with high efficiency, which has a good killing effect on cancer cells and cancer tissues, and almost has no toxic or side effects on normal tissues while achieving photo/acoustic dynamic therapy on tumors.

Abstract: A photosensitizer and derivative, application thereof. The photosensitizer has the structure of general formula I, wherein X is S or Se, Y is organic or inorganic ion, R1 and R2 are independently selected from H, alkyl, alkoxy, alkyl amido, alkyl azide and the like; R3 is selected from H, alkyl, alkoxy, amino sulfonyl, hydroxyl, carboxyl and the like, and L1 is a linker selected from —(CH2)n1— or —(CH2CH2O)n2—. The derivatives are molecular medicines with drug molecules of anticancer and chemotherapy or tumor targeting function connected to the said photosensitizer. The photosensitizer has excellent near infrared characteristics and low dark toxicity and is used in the field of photodynamic tumor therapy. The introduction of benzophenothiazine or benzophenoselenazine into derivatives with tumor-targeting function could improve the specific uptake of photosensitizer in tumor tissues.
