Abstract

The invention discloses a day-ahead market clearing model considering medium and long term transaction and wind power uncertainty, and belongs to the technical field of power market transaction. The method comprises the steps of firstly obtaining basic data required for day-ahead market clearing, then establishing a day-ahead market clearing model considering medium and long term transaction and wind power uncertainty based on the basic data, solving to obtain a day-ahead clearing result, and finally settling a power generation side main body according to the clearing result. According to themethod, medium and long term transaction, wind power uncertainty and a day-ahead clearing model are organically combined, a simulation model is provided for analyzing a medium and long term contract execution mode, a transaction mode of wind power participation in the market and auxiliary service transaction, and the transition of the power market in China from an electric quantity market mainly based on medium and long term transaction to a power spot market is facilitated.

Description

technical field [0001] The invention relates to the field of electric power market, especially for the clearing model of the electric power market, which is a day-ahead market clearing model considering medium and long-term transactions and uncertainty of wind power. Background technique [0002] In 2015, a new round of power market reform was driven by the "Zhongfa No. 9" document. This round of reform clearly stated that the construction of my country's power market should be based on both medium and long-term contract transactions and spot market transactions, and gradually build medium and long-term transactions to avoid risks. , a power market system that optimizes the allocation of power resources with spot transactions and discovers real price signals. Therefore, how to effectively establish a spot market that takes into account medium and long-term contract transactions has become the key to deepening the reform of the power system. [0003] Different from the mature...
