Robust Energy Storage Configuration of Integrated Energy System Considering Multiple Uncertainties

A robust configuration method of energy storage in integrated energy systems (IES) considering the uncertainty of renewable energy and electrical/thermal/cold load is proposed. First, based on the energy hub (EH) model, a general configuration model of electrical/thermal/cold energy storage is established. Secondly, a two-stage robust configuration model of electrical/thermal/cold energy storage is established on the basis of the deterministic model. The upper layer of the model is the planning problem of energy storage, and the lower model is the operation problem of IES. The uncertainty parameter set is established, to control the robustness of the model, the set introduces robust measures from both the quantity dimension and time dimension of the uncertainty parameter. Finally, the column and constraint generation algorithm (C & CG) is used to decompose the model into a main problem and a sub problem. The calculation example shows the effectiveness of the proposed method.
