Problems solved by technology

[0003] The purpose of the present invention is to provide a two-tier clearing pricing method in the spot market considering the coordination of water and fire. The method is based on the standard optimization model of the spot market and a mature mathematical optimization algorithm, comprehensively considering various complex constraints, and can quickly and accurately identify needs. A set of active integer variables for branch calculations to solve problems where numerous discrete variables and complex constraints of different classes greatly affect the computational efficiency of the problem

Abstract

The invention discloses a double-layer clearing and pricing method in the spot market considering water and fire coordination. The constrained economic dispatch model obtains the first round of clearing results; the basic data is input into the preset SCUC model considering the constraints of hydropower water abandonment to obtain the unit combination results; the safety constraint economic dispatch model considering the constraints of hydropower and water abandonment is established to obtain the second round of Clear the result; judge whether the winning bid output in the two rounds of clearing results are consistent; if so, output the clearing result; if not, take the unit output value in the second clearing result as the fixed output of the hydroelectric unit; The node electricity price calculation model that does not consider the constraints of hydropower and water abandonment is designed, and the node electricity price results are calculated; in this way, under the premise of ensuring the efficient clearing of the market, the optimal allocation of resources and the rational distribution of the interests of market players are realized.

Description

technical field [0001] The invention relates to the technical field of power dispatch automation, and in particular, to a double-layer clearing and pricing method in spot market considering water and fire coordination, a computer terminal device and a computer-readable storage medium. Background technique [0002] The essence of clearing the electricity spot market is to achieve optimal economic benefits on the premise of satisfying the constraints of safe operation of the system. In the process of market clearing, market operators need to consider the operating characteristics of multiple power sources in the management area and the relationship between different power sources. coordination relationship. During the construction of the spot market in some provincial / regional power grids in my country, where hydropower is the mainstay and thermal power is the supplement, the dispatching agency needs to consider the hydropower storage capacity limit, hydropower vibration area ...
