Abstract

The invention discloses an electricity-gas-heat energy storage collaborative planning method and system considering wind power uncertainty. The method comprises the steps: carrying out the classification processing of wind power historical data according to seasons, and obtaining a finite number of typical scene sets with a set probability; for each scene, considering energy conversion relation constraints of an electric load, a gas load and a thermal load, and establishing an electric-gas-thermal multi-type energy storage collaborative planning model by taking economic optimization as a target; and solving the model to obtain an optimal planning result considering the uncertainty of the wind field. According to the method, the wind power uncertainty model is established by adopting a scene method from the time dimension and by taking seasons as scene distinction. A scene in one year is decomposed into typical scenes in different seasons. In a wind power typical scene, economy and flexibility of the multi-energy storage planning method are verified.

Description

technical field

[0001] The invention relates to the technical field of comprehensive energy storage optimization, in particular to an electric-gas-thermal energy storage collaborative planning method and system considering the uncertainty of wind power. Background technique

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Renewable energy is developing rapidly, and wind power, as a typical renewable energy, has made a significant contribution to improving environmental pollution. However, the integration of large-scale and uncertain wind power poses great challenges to the integrated energy system. Due to the anti-peaking characteristics of wind power, it is difficult for the system to accept more wind power. As a flexible resource, energy storage can effectively increase the consumption of renewable energy. It can alleviate energy demand during peak periods ...
