The invention provides an electrolytic manganese residue-based ointment filling material which comprises original electrolytic manganese residues, carbide slag and an electrolytic manganese residue cementing agent, wherein the electrolytic manganese residue cementing agent comprises ground electrolytic manganese residue powder, boiling furnace slag, cement kiln ash, phosphorus slag powder, petroleum coke desulfurized fly ash and additives. A preparation method of the material comprises the following steps: by taking the original electrolytic manganese residues as a basic raw material, adding the carbide slag and the electrolytic manganese residue cementing agent, rapidly stirring for 10-20 minutes, adding water till the water content of the filling material meets a provided value, and further stirring for 10-30 minutes, thereby obtaining the electrolytic manganese residue-based ointment filling material. Compared with a cement type mine filling material, the electrolytic manganese residue-based ointment filling material provided by the invention is good in filling mobility, relatively rapid in strength increase, good in slight swelling property and low in heavy metal leaching concentration.

The invention relates to the technical field of power grids, in particular to a dynamic micro-grid group P2P transaction method based on priority matching. Determine the transaction roles, where the transaction roles include a buyer and a seller, and calculate the priority index according to the transaction role, and sort according to the absolute value of the priority index; S15 , perform transaction matching based on the sorting of the priority index value, and after the matching is successful The buyers and sellers of the matching pair announce their respective quotations and supply and demand to the matched counterparty; S16, calculate the supply and demand ratio, and each microgrid that is successfully matched updates the quotation according to the quotation model based on the supply and demand ratio; S17, according to the supply and demand and the quotations of both parties, Generate trades according to the trade price model. In the present invention, the micro-grid only needs to announce the quotation and supply and demand to the counterparty who is successfully matched, so the privacy security is better guaranteed.

The invention discloses a scheduling optimization method for an active power distribution system in an industrial park considering the peak-shaving demand of the power grid. The photovoltaic power generation unit PV, the all-vanadium liquid flow battery energy storage system VRB and the industrial load are used as industrial loads to participate in considering the peak-shaving demand of the power grid. The dispatching unit of the active power distribution system in the park establishes the physical model of each dispatching unit; the dynamic dispatching optimization problem of the active power distribution system in the industrial park considering the peak-shaving demand of the power grid is established as a DTMDP model; the Q-learning algorithm based on simulated annealing is used to carry out the DTMDP model Strategy solution, the obtained optimization control strategy is used to guide the system to choose a reasonable action plan in the actual operation process, and realize the system scheduling optimization. The invention can effectively solve the peak-shaving demand problem of the power grid under the consideration of the randomness on both sides of the source and load, promote the on-site consumption of new energy, and improve the operation economy of the active power distribution system and the operation stability of the power system.

The invention relates to a treatment method of cement kiln incineration polluted soil. The method aims to implement stabilization, reduction, harmless treatment and recovery of polluted soil. The scheme is as follows: the method comprises the following steps: A. polluted soil is transported into the factory and subjected to platform balance metering, and enters a polluted soil crusher anti-blocking discharge bin; B. the polluted soil enters a multistage impact crusher and is subjected to crushing treatment; C. the polluted soil is sent into a finished product stocking shed by a stocker and subjected to stocking and homogenized storage; D. the material is transported and poured by a special polluted soil truck into an anti-blocking discharge hopper; E. the material is directly conveyed by a metering conveyor into a cone below a dripping box in a kiln tail decomposition furnace; F. high-temperature gas of the kiln tail decomposition furnace is used for evaporating moisture in the polluted soil, the polluted soil is incinerated, the incineration ash enters a rotary kiln, and the waste slag is directly used as a cement raw material; and G. hot fume after polluted soil incineration enters a kiln tail system and performs heat exchange with an in-kiln crude material, and meanwhile, part of harmful substances are decomposed. The method is suitable for treating polluted soil.

The invention belongs to the technical field of intelligent power grids, and particularly relates to an air conditioner time-sharing scheduling method based on demand response. The air conditioner time-sharing scheduling method based on demand response includes the steps that a power supply operator installs photovoltaic power generation devices connected to the grid for users; the users are classified into two categories according to the temperature variation ranges set for air conditioners by the users, and the users form an alliance along with the photovoltaic power generation devices; the photovoltaic power generation quantity, the baseline load, the power grid power price, the indoor temperature, the outdoor temperature and the rated power of the air conditioners at the current time are obtained; according to the different time periods of the summit time, the flat time and the low tide time of the current power grid power price, the indoor temperature and the outdoor temperature, and in combination with the current photovoltaic power generation quantity, the start and stop of the air conditioners are controlled; the profits gained by the alliance are calculated, the contribution of the two categories of users and the photovoltaic power generation devices to the profits of the alliance is quantified through a Sharpley value method and the profits are distributed. The air conditioner time-sharing scheduling method based on demand response effectively improves the profits of the users and elimination of the photovoltaic resources on the spot, is low in time complexity and low in calculation cost and can be easily achieved on the user side.
