The present application discloses a biological valve material which is a swim bladder derived biological valve material. The present application also discloses a method for preparing the biological valve material, includes: decellularizing a raw swim bladder; and cross-linking the decellularized swim bladder with a cross-linking agent. The present application also discloses use of the biological valve material, wherein the biological valve material is used for preparing one or more of a biological heart valve, a biological patch, and an artificial blood vessel. The present application also discloses a cross-linking agent for a bio-based material, including a cross-linking compound and an organic solvent. The cross-linking compound includes a polyphenol compound. The present application also discloses use of the cross-linking agent, wherein the cross-linking agent is used to cross-link the bio-based material after the decellularization treatment.

A wind power accommodation oriented low-carbon operation scheduling method for offshore oil and gas platform energy system. Aiming at uncertainty and fluctuation of wind power, the method constructs a target linear planning model. A target function result of the model is the lowest power synthesis of a gas generator. Constraints of the model include a gas power generation and wind power synergetic ramp flexibility constraint, a gas generating capacity and wind power capacity synergetic flexibility constraint, an operating characteristic constraint of a gas generator set, an operating characteristic constraint of a gas compressor and a grid-connected operating characteristic constraint of a wind generator. The scheduling method can effectively cope with the uncertainty and fluctuation of wind power, so as to reduce carbon emission of the energy system of the offshore oil and gas field.
