Abstract

The invention discloses an energy-saving power generation dispatching planning method and system. The energy-saving power generation dispatching planning method comprises the following steps: determining operating time according to planning time and maintenance time, and determining a ranking index of a unit according to coal consumption; and determining a peak regulation coefficient of the unit according to maximum output, minimum output, the operating time, station power consumption rate, preset electric quantity of a power grid, load rate difference regulation coefficients and the ranking index; and determining the generating capacity within the planning time according to the maximum output, the minimum output, the operating time and the peak regulation coefficient, determining on-grid energy within the planning time according to the generating capacity and the station power consumption rate, and determining the load rate within the planning time according to the generating capacity, installed capacity and the operating time. The maximum output and the minimum output are the maximum output and the minimum output after a non-heat supply unit and a heat supply unit supply heat; participation of the heat supply unit into peak regulation is considered; energy-saving power generation dispatching requirements and peak regulation requirements of a power system are taken into account; and an energy-saving power generation dispatching plan obtained through the energy-saving power generation dispatching planning method and system has relatively high practicability.

Description

technical field [0001] The invention relates to the field of power system dispatching operation, in particular to an energy-saving power generation dispatching planning method and system. Background technique [0002] Energy shortage is a major problem of the 21st century. my country's power system is dominated by coal power, and power generation companies consume a large amount of primary energy. In order to alleviate energy problems and achieve sustainable development, the power industry has adopted a series of measures: First, in 2007, the state launched the "Energy-saving Power Generation Dispatching Method (Trial)", and carried out energy-saving power generation dispatching pilot projects in some provinces, and units with low coal consumption were given priority power generation; second, put into operation cogeneration units (hereinafter referred to as heating units) to improve the comprehensive utilization efficiency of energy, and the proportion of heating units in s...
