Embodiment Construction

[0024] The present invention relates to an optimization method for power generation plan under the annual electricity progress tracking and dispatching mode. The following is a preferred implementation case of the present invention, which includes the preparation process of the day-ahead power generation plan under the annual power progress tracking and dispatching mode by adopting the method of the present invention. Its characteristics, purposes and advantages can be seen from the description of the embodiment.

[0025] In the process of power grid day-ahead power generation planning, it is necessary to combine the completion of power contracts of each unit, consider factors such as load balance constraints, unit operation constraints, and grid security constraints, and require most of the units to follow the trend of system load changes, and compile the next day 96 power generation plan for a time period.

[0026] The power generation plan optimization method of the present...

Abstract

The invention discloses a method for optimizing a power generation plan in a mode of tracing scheduling of an annual electric quantity progress. The method comprises the following steps of: firstly, calculating a currently-expected power-output plan of a machine set by taking annual progress control as a target; and secondly, optimizing and calculating the power generation plan of the machine set by taking a minimum deviation of the expected power-output plan as the target and considering all kinds of constraint conditions. A reasonable scheduling plan is made by two-stage decision links of expected plan making and optimization of a safety constraint power generation plan, the effective synchronous execution of a contract electric quantity is guaranteed, safe and fair united optimization is realized, and the intelligent level and decision making capacity of power generation scheduling can be improved conveniently. Meanwhile, the method is characterized by low calculation strength and strong adaptability and is more suitable for promotion and application in scheduling institutions at all levels in China.

Description

technical field [0001] The invention belongs to the technical field of electric power system scheduling automation, and relates to a power generation plan optimization method under the annual power schedule tracking scheduling mode. Background technique [0002] Annual electricity progress tracking and dispatching is the main dispatching mode in my country at present, and its concept is very extensive. First of all, it is reflected in the signing of the annual contract of the power plant, which requires the signing of the total annual contract of each power plant to be fair, that is, according to the national policy, the annual contract is signed based on the principle of the utilization hours of the same type of units; secondly, it reflects the implementation of the contract, requiring Both parties of the factory and the network strictly implement the signed contract. The shortfall caused by the power grid needs to be made up, and the shortfall caused by the power plant’s n...
