Abstract

In view of the acceleration of the market-oriented process of renewable energy, combined with the current situation of domestic power market construction, the provincial medium and long-term transaction mechanism to promote the market-oriented consumption of renewable energy and the connection of the spot market are studied. Based on the characteristics of resource distribution, an electricity decomposition model aiming at the consumption of renewable energy and the completion schedule deviation of conventional unit contract is proposed. Aiming at the uncertainty of renewable energy, an ANFIS prediction technology based on multi scenario set is proposed to predict the medium and long-term electricity consumption of renewable energy. On this basis, electricity decomposition is carried out to improve the utilization rate of renewable energy; Establish a day ahead market clearing strategy taking into account the uncertainty of medium and long-term contract decomposition electricity and renewable energy output, ensure the physical implementation of medium and long-term contract electricity and realize the orderly connection with the spot market. Finally, an example is given to verify the effectiveness and practicability of the proposed model.
