Problems solved by technology

[0006] At present, when the power system dispatching center makes a short-term power generation plan, it generally sets the output curve of the generator set manually based on operating experience. Difficulty in practical implementation
At the same time, empirical scheduling cannot effectively consider the safety of the power grid, and the unit combination scheme obtained is often not feasible in practice, and the unit combination scheme needs to be adjusted repeatedly during operation, which makes it difficult to ensure the safety and economy of dispatching operation, and also brings difficulties to operators. huge workload

Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings.

[0044] Such as figure 1 As shown, a preferred implementation case of the present invention includes adopting the method of the present invention, the day-ahead power generation plan preparation process under the coordinated dispatch mode of intermittent energy sources and conventional energy sources, its characteristics, purposes and advantages can be seen from the description of the embodiments see.

[0045] In the process of power grid day-ahead power generation planning, it is necessary to combine the next day's wind power forecast and the available status of each conventional unit, consider factors such as load balance constraints, unit operation constraints, and grid security constraints, and require the acceptance of intermittent energy sources such as wind power. The power generation plan for 96 periods of the next day.

[0046] The power generation plan optim...

Abstract

The invention discloses a generation plan optimizing method in an intermittent energy and conventional energy coordinated dispatching mode, belonging to the technical field of power system dispatching automation. To minimize the generation cost of the system, the coordinated dispatching of an intermittent energy unit and a conventional energy unit is comprehensively considered, and various constraint conditions are taken into consideration to optimize the generation plan of a computing group, thereby ensuring the safe access of intermittent energy such as wind power and the like, and being favorable for improving the intelligence level and decision making ability of the generation dispatching after the access of the intermittent energy. Meanwhile, the method has the characteristics of low computing strength and strong adaptability, and is more suitable for the popularization and application of the dispatching mechanisms with relatively high wind power access power in our country.

Description

technical field [0001] The invention belongs to the technical field of power system scheduling automation, and in particular relates to a power generation plan optimization method under the coordinated scheduling mode of intermittent energy and conventional energy. Background technique [0002] At present, energy saving, emission reduction and curbing climate warming have become a common challenge and an important issue facing the whole world. The Chinese government attaches great importance to the work of energy conservation and emission reduction in the power industry, and proposes to implement energy-saving power generation dispatching in the power field, improve the efficiency of energy use in the power industry, reduce environmental pollution, and promote the adjustment of energy and power structures. This is a major measure for the electric power industry to implement the scientific outlook on development and build a harmonious socialist society, and it is an inevitabl...
