Problems solved by technology

[0002] In the traditional mid-to-long term dispatching, the annual contract power is compiled only based on the average annual utilization hours of the units, without considering the adjustment of the market mechanism, resulting in a plan that is not the least costly; at the same time, it does not consider the generation of thermal power units after the wind power is connected. The monthly power generation plan of thermal power units cannot be obtained from these two aspects.
[0003] In the process of realizing the present invention, the inventor found that at least there are defects such as high input cost and poor planning accuracy in the prior art

Abstract

The invention discloses a thermal power generating unit medium and long-term time sequence progressive power generation coordination algorithm considering wind power uncertainty. The algorithm comprises the following steps: connecting with data of a wind power farm to input wind power farm annual power generation and monthly power generation predicted values to a program; calculating a monthly power generation plan of each thermal power generating unit based on the data, the predicted value and monthly power generation predicted values of hydroelectric generating set annual power generation, the predicted value and monthly predicted values of cross-regional transmission electric quantity, and the annual predicted value and monthly predicted values of load; performing rolling correction on the monthly power generation scheme according to the monthly maximum and minimum power generation limitations of the unit and a maintenance plan and outputting the plan. The thermal power generating unit medium and long-term time sequence progressive power generation coordination algorithm considering the wind power uncertainty can overcome the defects such as high investment cost and poor plan accuracy in the prior art so as to realize the advantages of low investment cost and good plan accuracy.

Description

technical field [0001] The invention relates to the technical field of power system dispatching operation, in particular to a medium- and long-term time-sequence progressive power generation coordination algorithm for thermal power units that takes wind power uncertainty into account. Background technique [0002] In the traditional mid-to-long term dispatching, the annual contract power is compiled only based on the average annual utilization hours of the units, without considering the adjustment of the market mechanism, resulting in a plan that is not the least costly; at the same time, it does not consider the generation of thermal power units after the wind power is connected. Due to the influence of the quantity, the monthly power generation plan of the thermal power unit cannot be obtained from these two aspects. [0003] In the process of realizing the present invention, the inventors found that the prior art at least has defects such as high input cost and poor plann...
