Abstract: A method and apparatus for optimally configuring a capacity of a high-proportion new energy system, a device, and a medium, which belong to the field of new energy system optimization and are used for solving the problems of insufficient flexibility of the high-proportion new energy system during the heating period and difficult consumption of renewable energy. The method includes: constructing a high-proportion new energy system structure; establishing a concentrating solar power (CSP) unit model and a combined heat and power (CHP) unit model based on the proposed structure; establishing a high-proportion new energy system collaborative optimization model based on the proposed unit models; acquiring relevant data of various units and renewable resource data; and obtaining a capacity configuration and operation optimization scheme of various units in the high-proportion new energy system according to the established model, thereby improving the renewable energy consumption of the system.

Abstract: The present invention pertains to the field of oilfield stimulation technologies for oil and gas field development, in particular to an instant soluble temperature and salt resistant polyacrylamide and the preparation method and application thereof, and the polyacrylamide is modified by adding rigid temperature and salt resistant monomer containing benzene ring and cationic fluorinated hydrophobic monomer on the basis of acrylamide monomer and sodium acrylate monomer, and then polymerized to obtain instant soluble temperature and salt resistant polyacrylamide. The temperature and salt resistant monomer containing benzene ring can improve the thermal stability and temperature and salt resistance of polyacrylamide, while the long-chain cationic fluorinated hydrophobic monomer can enhance the hydrophobicity of polymer. The comprehensive properties of polymer is improved by appropriate intermolecular association.
