Two-stage Robust Optimization of Integrated Energy System Considering Flexible Source-load Coordinated Response
To further improve the operation economy and low-carbon performance of an integrated energy system(IES),a low-carbon economic dispatching model of a rural IES considering the flexible source-load response is proposed.First,based on the comprehensive demand response of biomass thermoelectric units and multi-type loads,a flexible source-load coordinated response mechanism is put forward to analyze the source-load coordinated response mechanism.At the same time,based on the concept of average value,a multi-type load comprehensive satisfaction index is de-signed to accurately assess the overall satisfaction level of load.Second,a two-stage robust optimization considering un-certainties is proposed to deal with the fluctuation characteristics of gas production from a biogas digester.Finally,the column constraint generation algorithm is used to solve the model,and the analysis result shows that the proposed meth-od can reduce the operating cost by 24.11％and the carbon emissions by 57.10％.
