Method and device for determining ideal power generation progress index of power plant

Abstract

The invention provides a method and device for determining an ideal power generation progress indicator of a power plant. The method comprises the steps that maximum output and maintenance information of all units of the power plant in every month are acquired; predicated power generation load of the whole network in every month is acquired; the power generation capacity of the power plant in every month is determined according to the maximum output, maintenance capacity and maintenance lasting days of each unit as well as the number of days in every month; the total amount of the power generation capacity of the power plant from January to the m month is determined according to the power generation capacity of the power plant in every month and the obtained annual power generation capacity of the power plant; a contract progress indicator of the m month power generation capacity of the power plant is determined according to the specific value of the total amount and the annual power generation capacity; the ideal power generation progress indicator of the power plant in the m month is determined according to the contract progress indicator, the predicated power generation load of every month, the number of days in the whole year and the number of days from January 1 of the year to the last day of the m month. According to the method and device for determining the ideal power generation progress indicator of the power plant, the actual operation condition of the grid is considered, and the provided ideal power generation progress indicator is more reasonable.

Description

technical field [0001] The invention relates to the technical field of power system dispatching operation, in particular to a method for determining an ideal power generation schedule index of a power plant and a device for determining an ideal power generation schedule index for a power plant. Background technique [0002] The monthly power generation plan is one of the central links in the operation of the electricity market. In the power trading work, it is usually necessary to decompose the annual power plan of the power plant into each month. When decomposing the power plan, the monthly load rate of the power plant should be balanced as much as possible to reduce the risk of dispatch operation. At the same time, the load rate of each power plant in the monthly plan should be as close as possible to maintain the fairness of dispatch. The completion progress of the annual plan is an important process control indicator, and a set of power generation progress indicators ne...

Problems solved by technology

This kind of power generation schedule index does not take into account the actual operation of the power grid, so the power generation plan formulated according to the power generation schedule index has defects such as irrationality
