Time sequence progressive power dispatching method

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 monthof 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 guidesafe and economic operation of electric system better.

Description

Technical field [0001] The invention belongs to the technical field of power dispatch automation, and relates to a time sequence progressive coordination method, a differentiated power generation plan decision method of each sequence link, and an actual operation mode. Background technique [0002] Power dispatching is the main means for the grid to adopt various optimized control technologies, coordinate various power generation resources, maintain the balance of supply and demand, and ensure the safe and economic operation of the 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. Dispatching goals involve grid operating costs and grid security / Reliability indicators, etc. The scheduling variables are the unit start-up and shutdown status I and unit outp...

Problems solved by technology

Although advanced optimization models have been greatly developed and widely used, these methods are purely mathematical and theoretical, emphasizing the optimization of a single timing link, and lack of overall forward-looking and backward-looking breadth optimization in terms of different timing coordination, so they have not really achieved The whole-process optimization effect of the power grid restricts the improvement of the lean management level of the entire dispatch plan, making it difficult to achieve the best results in power grid operating costs and power grid security / reliability indicators
