The invention designs a coloured ceramsite and a preparation method thereof and belongs to the technical field of inorganic non-metallic materials. The preparation method of the coloured ceramsite comprises the following steps: uniformly mixing 50-65% of gold ore tailing, 20-30% of silt of the Yellow River, 3-4% of pulverized coal, 0 or 3-5% of cobalt oxide, 0 or 4-6% of manganese oxide and 25-30% of water in a mass ratio, making spherical particles with the diameter of 8-12mm by adopting a moulding machine, drying, putting the spherical particles into a sintering kiln, controlling atmosphere in the sintering kiln, and sequentially carrying out preheating, sintering and cooling, so that the coloured ceramsite is obtained. The preparation method of the coloured ceramsite has the advantages that gold ore tailing and slit of the Yellow River are adopted as main raw materials, recycling of waste in nature is realized, and environmental protection is facilitated; cobalt oxide and manganese oxide ...

The invention discloses a regional power supply capacity configuration method considering multi-type energy storage in a market environment, and belongs to the technical field of power systems. The invention aims to solve the problem that the existing planning method cannot accurately guide the construction capacity of the multi-type energy storage equipment of the multi-type power generation main body, so that the construction capacity of the unit cannot be matched with the actual demand. According to the method, a prediction model is established to predict the load demand of the next year, the annual planned power generation amount of different power generation subjects and the transaction price of different power generation subjects, typical daily time sequence simulation modeling is carried out on a to-be-configured power supply capacity area, and the typical daily time sequence output condition and expected income of multi-type energy storage are obtained. And in combination with the ...
