Method for calculating clearing price in centralized bidding transaction of pumping electric quantity

Abstract

The invention relates to a calculation method for clearing electricity prices in centralized bidding transactions of pumped electricity, comprising the following steps: 1) In the centralized bidding transactions of pumped electricity, each market member submits the declared electricity quantity and the declared electricity price, and checks the upper limit of the declared electricity quantity and the declared electricity price Lower limit; 2) Order the transactions of each market member to obtain the transaction sequence; 3) Calculate the transaction clearing price of each market member, and each market member will make transactions in turn according to the transaction sequence until the sum of the transaction and clearing electricity is equal to the centralized bidding transaction electricity , and get the transaction clearing list, and the centralized auction transaction ends. Compared with the prior art, the present invention has the advantages of eliminating restrictions, optimizing transaction ordering, clearing in two steps, and considering positive and negative transaction factors.

Description

technical field [0001] The invention relates to the field of electric power bidding, in particular to a calculation method for clearing electricity prices in centralized bidding transactions of pumped electricity. Background technique [0002] According to relevant national documents, pumped storage power stations implement a two-part electricity price system, of which the capacity electricity price is determined in accordance with the principle of making up for the fixed costs of the pumped storage power station and the permitted income. 50% will be digested by power grid companies, and 25% will be borne by power generation companies and users. Among them, 25% of the capacity electricity charges that power generation companies need to bear are solved by grid companies bidding to purchase pumped water from power generation companies under their jurisdiction. [0003] The formula for calculating the capacity electricity fee borne by each power generation enterprise is: [0...

Problems solved by technology

[0009] Under the new policy situation, it is difficult for the above-mentioned traditional water pumping power plan or semi-plan apportionment method to adapt to the new power market environment. It is urgent to change the traditional trading model and use market means to achieve optimal allocation of resources.
