Problems solved by technology

However, in integrated energy systems, the coupling characteristics of electricity, heat, and gas are usually ignored, and some studies have not considered the impact of wind power uncertainty
[0006] So far, few studies have focused on the coordinated planning of electricity, gas, and thermal multi-energy storage considering wind power and network constraints; at the same time, the research at this stage is not comprehensive on the interaction between different energy storage methods

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 ...
