Internal benefit allocation method for virtual power plant in participation in medium-and-long-term power transaction

Abstract

The invention relates to an internal benefit allocation method for a virtual power plant in participation in medium-and-long-term power transaction. The method comprises the following steps: step 1, constructing an evaluation index system for representing contribution degrees of internal members of the virtual power plant in participation in power transaction; step 2, according to the evaluation index system of the contribution degree of the internal members of the virtual power plant in participation in the power transaction established in the step 1, acquiring operation data of the internalmembers of the virtual power plant; and step 3, calculating the comprehensive contribution degree of the internal members of the virtual power plant participating in the medium-and-long-term power transaction according to the operation data of the internal members of the virtual power plant acquired in the step 2 so as to obtain a benefit allocation result of each internal member of the virtual power plant. Effective contribution degrees of different types of market subjects in the virtual power plant to electric energy balance or auxiliary services can be comprehensively considered, and respective benefit allocation coefficients are determined, so that the benefit allocation result can reflect the value contribution of the market subjects, and the economy and competitiveness of the marketsubjects are improved.

Description

technical field [0001] The invention belongs to the technical field of electric power trading, and relates to an internal benefit sharing method for electric power trading, in particular to an internal benefit sharing method for virtual power plants participating in medium and long-term power trading. Background technique [0002] With the widespread access of distributed power sources, energy storage, electric vehicles and various flexible load resources, the virtual power plant formed with the help of advanced control systems and communication technologies can realize the effective aggregation of the above-mentioned controllable resources, and jointly participate in the power market and Ancillary Services Marketplace Transactions. The "Basic Rules for Mid- and Long-Term Electric Power Transactions (Provisional)" proposes to encourage energy storage equipment and demand-side resources to participate in mid- and long-term electric power transactions and provide ancillary ser...
