Problems solved by technology
With the transformation of urban heating from heating boilers to combined heat and power heating, the heat load of heating units increases year by year, and the electrical load also increases, resulting in a decrease in the peak-shaving capacity of thermal power units, which further causes difficulties in peak-shaving of the power grid. Insufficient new energy consumption capacity and other issues
[0003] The regional power grid needs to verify the minimum output of the heating season every year. The existing technology obtains the minimum output by manually analyzing the operation data of each heating unit in the network in the previous heating season. It is impossible to predict and obtain accurate minimum output data.

The invention provides a method and a device for predicting the minimum output of a regional power grid. The regional power grid minimum output prediction method comprises the following steps: determining a power plant predicted heat supply load according to historical power plant weather characteristics and future power plant weather characteristics; determining a minimum output prediction result of the power plant according to the predicted heat supply load of the power plant, the thermoelectric relation curve of the maximum heat supply capacity of the unit, the heat supply load interval of the unit and the output electric power interval of the unit; and determining a minimum output prediction result of the regional power grid according to the minimum output prediction result of the power plant. According to the method, the minimum output data of the regional power grid can be accurately predicted, more detailed and reasonable data support is provided for dispatching operation of the regional power grid, and the technical communication between the power grid and a power supply point and the peak regulation capacity of the regional power grid in the heat supply season are effectively enhanced.
Description
technical field [0001] The invention relates to the field of electrical technology, in particular to a method and device for predicting the minimum output of a regional power grid. Background technique [0002] Most of the existing power stations are combined heat and power units, and the heating period in winter is operated in a thermally constant power mode. With the transformation of urban heating from heating boilers to combined heat and power heating, the heat load of heating units increases year by year, and the electrical load also increases, resulting in a decrease in the peak-shaving capacity of thermal power units, which further causes difficulties in peak-shaving of the power grid. Insufficient new energy consumption capacity and other issues. [0003] The regional power grid needs to verify the minimum output of the heating season every year. The existing technology obtains the minimum output by manually analyzing the operation data of each heating unit in the n...
