A Calculation Method for the Impact of Virtual Bidding on Node Price Difference in Day-ahead Electricity Market

Abstract

The invention proposes a calculation method for the influence of virtual bidding on the node price difference in the day-ahead power market, which belongs to the technical field of power market transactions. This method first obtains the calculated basic data of power grid system transactions corresponding to the day-ahead power market, and constructs a unified clearing model for power transactions in the day-ahead power market based on the basic data; using the solution results of the above model, establishes a security-constrained economic dispatch model of the day-ahead power market and solves it , to obtain the feasible bidding volume range and node price difference corresponding to the set virtual bidding volume; after repeated iterations, the ladder-like curve of the impact of virtual bidding on the day-ahead electricity market node price difference is finally obtained with the virtual bidding volume as the independent variable and the node price difference as the dependent variable . The invention solves the problem of how to accurately describe the non-linear relationship between the virtual bidding volume and the node price difference in the day-ahead power market, and can provide a calculation tool for identifying the speculative space of market members in advance, so as to ensure the efficiency and orderliness of the power market.

Description

technical field [0001] The invention belongs to the technical field of electric power market transactions, and particularly proposes a calculation method for the influence of virtual bidding on node price differences in the day-ahead electric power market. Background technique [0002] As an important part of the electricity market trading system, the electricity financial market can provide market members with effective financial tools to avoid risks in the spot market, absorb a large amount of capital into the electricity market, improve the liquidity of transactions in the electricity market, and promote the efficiency and stability of the electricity market operation. As a kind of power financial derivatives, virtual bidding can have an impact on the power spot market while trading in the power financial market, such as blocking a specific day-ahead power market line; using this influence, market members can speculate to virtual The bidding method artificially causes ch...
