Embodiment Construction

[0036] The present invention will be further described below in conjunction with drawings and embodiments.

[0037] 1. Unit output dimension expansion

[0038] How to realize the identification and classification of multi-transaction components is the basis for establishing unit combination problems considering external power transmission transactions, cross-provincial and cross-region tie-line transactions and security constraints.

[0039] Such as figure 1 As shown, the original unit combination model considering safety constraints is a two-dimensional model, and the unit output in the model is a two-dimensional continuous variable related to time and unit. Specifically, each unit has a power output state within a certain set time length; a certain unit has a power output state in each time period within the studied time length.

[0040] When multiple transaction components are introduced, the power generated by each unit has the attribute of transaction types. It can be ...

Abstract

The invention discloses a unit combination acquisition method considering external power transmission transactions, cross-province and cross-region tie-line transactions, and safety constraints. The method takes the transaction plan and operation plan of the power company as the background, and reflects the transaction types and requirements for power transactions. For the problem of the economic characteristics of the rules, a mathematical model oriented to transaction components is established. The optimized objective function is to minimize the transaction cost of the power company’s purchase of external power transmission transactions and cross-province and cross-region contact lines. Physical constraints and transaction component constraints can help power companies that need to consider trading varieties and rules to formulate transaction plans and operating plans, improve the scientificity and effectiveness of decision-making, and help optimize power companies' power purchase strategies and power purchase costs. Lean operation level of power trading business.

Description

technical field [0001] The invention belongs to the field of unit combination of electric power companies considering transaction components and safety constraints, and in particular relates to the formulation of an operation plan considering external power transmission transactions and cross-province and cross-region tie-line transactions. Background technique [0002] Judging from the power market reform in recent years, in the process of building a unified power market for regional power grids that the country mainly promotes, due to the influence of various factors such as different economic development levels and different power price levels in various provinces, the power market reform has encountered difficulties. The regional grid unified power market is also facing various complicated and sharp contradictions in dealing with the coordination of the interests of all parties involved. At the same time, in order to meet the needs of rapid social and economic developmen...
