End-to-end electric energy transaction auction method based on evaluation mechanism

Abstract

The invention discloses an end-to-end electric energy transaction auction method based on an evaluation mechanism, and the method comprises the following steps: (1) building a multi-attribute comprehensive evaluation system suitable for a distributed power generation market from three dimensions: electric energy transaction reliability, transaction stability and transaction economy, and evaluatingthe power supply service level of each user; (2) determining evaluation coefficients of the users according to the historical energy supply service data of the users; and (3) enabling an end-to-end electric energy auction model solving algorithm based on market evaluation to give a transaction clearing strategy in each time period. According to the invention, an end-to-end electric energy transaction auction strategy between microgrid users based on market evaluation is provided, credit and qualification constraints are provided for bidders in the electric power market, the bidders with goodevaluation are enabled to be advantageous, better income is obtained, and virtuous cycle of the electric power market is promoted.

Description

technical field [0001] The invention relates to the field of electricity market transaction algorithms, in particular to an end-to-end electric energy transaction bidding method based on an evaluation mechanism. Background technique [0002] In recent years, with the continuous development of the social economy, vigorously developing renewable energy including distributed photovoltaics has become a strategic choice for my country to ensure energy security, control environmental pollution, and respond to environmental and climate changes. Microgrid is considered to be an effective way to integrate distributed renewable energy for power management. Establish a distributed power generation market in the microgrid to carry out end-to-end energy transactions between users, and consume the electricity produced by photovoltaics through market means, which not only improves the utilization rate of photovoltaics, but also solves the problem of photovoltaic subsidies. With the deepen...
