Abstract

The invention discloses a method for constructing a typical scene library of a centralized spot market. The method comprises the following steps: extracting bidding behavior influence factors of a power producer; establishing a segmented bidding curve basic model of the power producer; determining a probability distribution model of the bidding electric quantity and the bidding price of each section of the segmented bidding curve; sampling based on the probability distribution model, and generating a typical market bidding scene of the power producer; generating a market boundary typical scene based on source network load characteristics of the power grid; combining and reducing the market bidding typical scene and the market boundary typical scene, and constructing a typical scene library for centralized spot market operation characteristic analysis. The method can construct a grouped scene set and generate a typical scene library according to different source network load characteristics and different bidding scenes of of the power producers, facilitates the construction of a market simulation multi-scene comparison analysis technology, displays the difference between different scenes, is of great significance in analyzing the operation characteristics of the centralized spot market and improving the safe operation level of the power grid under the market condition.

Description

technical field

[0001] The invention belongs to the technical field of electric power system dispatching automation, and in particular relates to a method for constructing a typical scene library suitable for analyzing the operation characteristics of a centralized spot market, and also relates to a construction device for a typical scene library suitable for analyzing the operation characteristics of a centralized spot market. Background technique

[0002] The power spot market mainly has two modes: decentralized and centralized, and the formation process of dispatching plans is different under different modes. Decentralized spot markets are suitable for areas with strong grid structures and light congestion, while centralized spot markets are suitable for areas with heavy congestion. Compared with the decentralized one, the centralized spot market implements the centralized optimization of power generation and consumption resources. Although it is more difficult in terms o...
