Abstract

Benefit from its flexible and environmentally friendly capability, integrated electricity and heat system (IEHS) is gaining more and more attention. In order to further release the flexibility from district heating system under variable mass flow and variable temperature (VF-VT) control strategy and cope with the direction variation of mass flow which would appear in practice, a unit commitment problem of IEHS is built in this paper employing implicit upwind differential scheme to characterize the temperature distribution along the pipeline. Additionally, piecewise linear method is adopted to reformulate the original problem into mixed-integer linear programming (MILP) problem, which could be solved efficiently with the related optimization tools. Case study demonstrated on a sixbus six-node IEHS confirmed the validity of the model.
