[0004] CN206291201U discloses a gas peak-shaving power station. When the power station uses electricity in peaks and valleys, by reducing the amount of coal burned, the gas produced by coal gasification and coal are supplied to the gas turbine for combustion and power generation. The peak-shaving method has a very wide peak-shaving range. Limited, high processing cost, and will affect the stable combustion of the boiler
[0005] CN107021603A discloses a sludge thermal drying system with low energy consumption. The system dries wet sludge by adding steam boilers, steam gas-water separators, steam compressors, etc. The equipment costs are expensive and the economy is not high

Description
technical field [0001] The invention relates to the technical field of power system peak regulation and energy storage, in particular to a device system and method for power station peak regulation and sludge drying and energy storage. Background technique [0002] In recent years, the installed capacity of new energy sources such as wind power and photovoltaics has ushered in explosive growth. However, the growth rate of electricity consumption at maximum load is not high, which is far lower than the growth rate of new energy installed capacity. In order to match the power generation capacity with the demand for electricity, thermal power generation can only be required to undertake the task of peak shaving of the power grid. If peak regulation is only performed by reducing the amount of fuel, the stable combustion of the boiler will be affected after the power generation of the thermal power unit is reduced to a certain extent. At this point, further peak shaving can onl...
