The invention discloses a construction method of a power grid carbon emission distribution network model. The construction method comprises the steps of obtaining node load data, generating capacity data and branch data of a power grid; forming an original data set and a load flow calculation result according to the data, and establishing a network topology model according to the original data set and the load flow calculation result; equivalently transplanting the loss power of each branch in the network topology model to a corresponding upstream node, keeping the size and direction of the power flow of each branch unchanged, and updating the network topology model; and based on the updated network topology model, constructing a carbon emission distribution network model in combination with a proportion sharing principle. According to the method, through real-time data acquisition, network topology modeling, carbon emission flow calculation and optimization solution, the carbon emission in the power system can be accurately quantified, and a scientific basis is provided for low-carbon scheduling and policy making of the power industry.

The invention belongs to the technical field of carbon quota allocation, discloses a traffic carbon quota allocation method and system based on a spatial SEE model, and aims to allocate carbon emission quotas according to the average population proportion of each province in a reference period and tilt the quotas to provinces and cities with more population in jurisdictions. The distribution mode not only reflects the actual population demand of each province and city, but also ensures that the carbon emission right can be distributed nationwide more fairly, the uneven resource distribution caused by the population scale difference is avoided, the investment-oriented ZSG-DEA model is adopted to carry out efficiency evaluation on the traffic carbon emission of each province in China, and the efficiency of the traffic carbon emission of each province in China is improved. And redistributing the carbon dioxide emission of the invalid DMU so as to realize the optimization of the carbon emission efficiency of each province. According to the invention, through scientific, reasonable and overall carbon quota distribution, the emission reduction task can be effectively decomposed, the realization of a dual-carbon target is promoted, and local governments are guided to clarify respective emission reduction targets and development positioning so as to formulate corresponding policies.

The invention provides an irrigation area water right distribution method based on a cooperative Stackelberg game, relates to the technical field of water resource management and distribution, and permits all irrigation areas to carry out water right transaction in a dispersed manner by constructing an irrigation area water market water right distribution and transaction analysis framework based on the cooperative Stackelberg game so as to realize cooperation and win-win. In the analysis framework, the irrigation district management bureau can set related condition value-at-risk parameters according to the risk preference degree of the irrigation district management bureau so as to balance the risk and the expected income and determine the water supply price, and the analysis framework defines the distribution rule of the income obtained by sharing the water right by using the GNB theory so as to excite the water right transaction among the irrigation districts, so that the water supply cost is reduced. And the fairness of benefit distribution is ensured. According to the method, the risk coping capability of the irrigation area water resource management system can be further improved, and the expected earnings of various participating roles under different risk avoidance levels are improved.

This utility model relates to the field of refractory materials technology for metallurgical equipment, and in particular to a ladle tank bottom lining structure with a gradient thickness, including ladle nozzle seat bricks, vertically laid tank bottom bricks, and lining wall bricks. The vertically laid tank bottom bricks include center bricks, intermediate bricks, and edge bricks, which are laid in a ring from the ladle nozzle seat bricks towards the edge of the ladle tank bottom, with the thickness d of the center bricks, intermediate bricks, and edge bricks increasing by 30mm to 40mm respectively. The lining wall bricks are set at the bottom of the inner wall of the ladle tank and connect with the edge bricks, with the thickness e of the lining wall bricks decreasing by 15mm to 20mm from bottom to top. The beneficial effects of this utility model are: by optimizing the thickness distribution, it improves thermal shock resistance, structural stability, and service life, and increases the steel loading capacity.

The embodiment of the invention discloses a distribution network fund investment decision-making method and device, a storage medium and computer equipment, and relates to the field of enterprise management. According to the method, whether each distribution network device in the list is input or not is decided by using the decision tree model, and the input device and the non-input device are identified according to the decision. Setting the score value of the input equipment as a preset maximum value; and for the non-input equipment, calculating a score value according to the plurality of working condition index values and a preset scoring standard. And carrying out arithmetic average on the score values of all the devices in the distribution network device list to obtain a comprehensive score value of the distribution network project. Comparing the comprehensive score value with a preset score threshold value, and if the comprehensive score value is higher than the threshold value, identifying the project as an input project; otherwise, identifying the project as a non-input project. The accuracy and efficiency of distribution network project investment decision making are improved, and powerful technical support is provided for enterprise development.
