Abstract

The invention discloses a spot market double-layer clearing pricing method considering water and fire coordination. The method comprises the steps of inputting basic data into a preset SCUC model which does not consider water and electricity water abandoning constraints to obtain a unit combination result; establishing a safety constraint economic dispatching model which does not consider the hydropower water abandoning constraint to obtain a first round of clearing result; inputting the basic data into a preset SCUC model considering hydropower water abandoning constraints to obtain a unit combination result; establishing a safety constraint economic dispatching model considering the hydropower abandoned water constraint to obtain a second round of clearing result; judging whether the bidwinning outputs in the two rounds of clearing results are consistent ; if so, outputting a clearing result; if not, taking the unit output value in the second round of clearing result as the fixed output of the hydroelectric generating set; and calculating a node electricity price result according to a preset node electricity price calculation model which does not consider hydroelectric water abandoning constraints. According to the invention, on the premise of ensuring efficient clearing of the market, resource optimal configuration and reasonable allocation of market subject benefits are realized.

Description

technical field [0001] The invention relates to the technical field of electric power dispatching automation, in particular to a two-layer clearing pricing method in the spot market considering the coordination of water and fire, computer terminal equipment and a computer-readable storage medium. Background technique [0002] The essence of power spot market clearing is to achieve optimal economic benefits under the premise of satisfying system security operation constraints. 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. In the construction process of some provincial / regional power grid spot markets in my country where hydropower is the mainstay and thermal power is the supplementary, dispatching agencies need to consider hydropower coordination scheduling issues such as hydropower storage capac...
