Abstract

The invention relates to the technical field of mobile terminals, and provides a hydropower water release and additional issue transaction management method and system. The method includes the steps that a mathematic model aimed at least comprehensive power purchase cost, the minimum power consumption and the lowest pollution discharge level is built, and the model is a multi-target optimization model; by means of a linear weighting method, the multi-target optimization model is converted into a single-target optimization model with compressive cost as a target; a unit order table is built; a hydropower emergency transaction mode is built on the basis of the unit order table; water release power sharing is carried out according to the transaction mode, cost is calculated according to a water release power price, and a transaction is finished. According to the method, the mathematic model for energy-saving power generation scheduling suitable for trans-provincial area power market situations is built, the mathematic model integrates economic benefits and hydropower water release and additional issue. By means of a heuristic method, the mode suitable for hydropower emergency transactions of the central China area is designed, and transaction computation and control is carried out according to the mode.

Description

technical field [0001] The invention belongs to the technical field of hydropower control, and in particular relates to a transaction management method and system for reducing, discarding, and increasing issuance of hydropower. Background technique [0002] In recent years, in order to save energy and realize a low-carbon economy, my country's "Eleventh Five-Year" development plan clearly puts forward relevant indicators for energy conservation and emission reduction. Relevant state departments have also promulgated the "Energy-saving Power Generation Dispatching Measures (Trial)", and formulated the overall goal of energy-saving and emission reduction during the "Eleventh Five-Year Plan" period: the line loss rate is reduced by 0.3 percentage points compared with 2005, and the sulfur dioxide emission is reduced by 30.39% compared with 2005 , reduce 178,600 tons. In order to make full use of hydropower resources, it is a major measure to promote energy conservation and emis...
