Embodiment Construction

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, further detailed description will be given below in conjunction with the accompanying drawings and implementations of the present invention.

[0025] A time-series progressive power scheduling method proposed by the present invention is characterized in that the power scheduling is to realize the scheduling cooperation and coordination of the three time-sequence links of month, week and day, and includes the following steps:

[0026] Step 1. Set up the three-level power dispatching time sequence link of monthly power generation plan, weekly power generation plan and daily power generation plan; wherein, the dispatching time range of the monthly power generation plan is the whole month, and the dispatching time range of the weekly power generation plan is 7 to 10 days (including Ordinary week and holiday golden week); the scheduling time range of the daily power generation pl...

Abstract

The invention relates to a time sequence progressive power dispatching method, belonging to the technical field of power dispatching automatization, comprising setting three-level dispatching time sequence steps of monthly power generation scheme, weekly power generation scheme, daily power generation scheme; a dispatching center configures a monthly power generation scheme mould of the next month according to the overhaul management information of each set and monthly load prediction information in the electric power plant of the next month and the planned electric quantity of the next month of each set to obtain the monthly power generation scheme of the next month; the dispatching center configures and solves a weekly power generation scheme mould of the next week according to the monthly power generation scheme of the current month to obtain the weekly power generation scheme of the next week; and the dispatching center configures and solves a daily power generation scheme mould according to the weekly power generation scheme of the current week to obtain the daily power generation scheme issued for power plant for carrying out within t+1 days; the practical generating capacity of each electric power plant is accounted at t+2 day, daily-weekly feedback is carried out at t+2 day, and daily-monthly feedback is carried out at the end of the current month. The method can guide safe and economic operation of electric system better.

Description

technical field [0001] The invention belongs to the technical field of electric power dispatching automation, and relates to a timing progressive coordination method, a differentiated power generation planning decision-making method for each timing link, and an actual operation mode. Background technique [0002] Power dispatching is the main means for the power grid to adopt various optimization control technologies, coordinate various power generation resources, maintain the balance between supply and demand, and ensure the safe and economical operation of the power grid. The essence of power dispatching work is a kind of industrial optimization problem of coordinating and arranging power production from the perspective of time and space under the condition of limited power generation and transmission resources within a certain time scale. Reliability indicators, etc., the scheduling variables are the start-stop state I of the unit and the output P of the unit, which are u...
