This invention discloses a real-time points clearing and settlement method and system supporting cross-border transactions, relating to the field of cross-border transaction technology. It includes establishing a third-party transaction platform, setting up an inspection-free fund account and an audit account. When a payer and payee conduct a transaction of amount b, the system automatically matches the transaction method for both parties. The customer confirms the transaction method, the transaction of amount b is conducted, a security audit is performed on the transaction, risk management is implemented, the transaction is completed, and the customer's transaction behavior is evaluated. Based on the evaluation results, the initial fund A is dynamically adjusted, and a dispute resolution database is established. This invention utilizes a real-time points clearing and settlement method supporting cross-border transactions, providing three transaction options based on the established accounts: an audit transaction channel, an inspection-free transaction channel, and a combined audit and inspection-free channel. This offers diverse transaction options, and under the inspection-free transaction channel, secure funds can be transacted first, followed by transaction fund auditing, thereby improving transaction efficiency.

The present application relates to the field of coking, synthetic ammonia and the like containing ammonia wastewater treatment, and discloses a novel ammonia evaporation energy-saving process system, a primary ammonia evaporation tower, an intermediate pressurizing pump set, a water flow regulating device, a secondary ammonia evaporation device, a flash tank, a steam ejector, a pressurizing pump set and a control unit. After the ammonia-containing wastewater is preliminarily treated by the primary ammonia evaporation tower, it is delivered to the secondary ammonia evaporation device by the pressurizing pump, and introduced into new steam for secondary ammonia evaporation. After the secondary ammonia evaporation, the wastewater flows into the flash tank to produce flash steam by cooling and pressure reduction, and the flash steam is pressurized by mixing with the new steam through the steam ejector, and then returns to the primary ammonia evaporation tower or the secondary ammonia evaporation device, so that the steam is recycled multiple times. The system can effectively reduce the new steam consumption by 35-45% under the premise of ensuring the stability of the ammonia nitrogen index of the effluent, improve the energy utilization rate, reduce carbon emissions, and is suitable for direct ammonia evaporation and indirect ammonia evaporation systems.

This invention proposes an optimization method for multi-virtual power plant (VPP) electricity-carbon sharing operation considering ideal returns, comprising the following steps: Step S1, establishing a single VPP model considering electricity-carbon trading among VPPs; Step S2, calculating the bargaining power of each VPP based on ideal returns, and establishing an MVPP asymmetric Nash bargaining model based on ideal returns; Step S3, solving the MVPP asymmetric Nash bargaining model based on ideal returns in two steps using the ADMM method to obtain the optimal solution. This invention can effectively promote the sharing of electricity and carbon quotas among VPPs.

The invention discloses an agricultural ecological water utilization potential mining method and system based on a block chain, and belongs to the technical field of agricultural information. The method comprises the following steps: collecting agricultural water data through the Internet of Things, and ensuring credibility through blockchain evidence storage; on the basis of on-chain data, dynamically accounting the gridding ecological water utilization potential by using a model fusing a physical mechanism and deep learning; a water right transfer and ecological compensation protocol is automatically generated and executed through an intelligent contract, and ownership transfer and payment automation are achieved; and constructing an incentive and on-chain governance mechanism based on contribution proof, distributing tokens according to data quality, water saving amount and governance participation, and updating system parameters through right proof voting. The system correspondingly comprises a data storage module, a potential accounting module, an intelligent contract module and an incentive management module. According to the method, credible evaluation, efficient conversion and sustainable operation of the agricultural water-saving potential are realized.

The invention provides an intelligent power system resource configuration method and system based on a block chain, and relates to the technical field of power system resource configuration, and the method comprises the steps: obtaining equipment resources and demand data to construct a topology layer, calculating a matching weight recognition combination relation to form an extended matching set, and carrying out resource allocation. Conflicts are detected through spatio-temporal indexes, the conflicts are resolved through a game propagation graph to generate a correlation graph, electrical partition verification is performed, the electrical partition is distributed to a block chain for verification, and finally resource configuration is executed through an intelligent contract. Accurate and efficient configuration of electric power resources can be realized, the operation reliability of the system is improved, and the configuration cost is reduced.
