Power Systems Flexibility from District Heating Networks

Coupling heat and electricity systems can improve the overall flexibility of the energy system and facilitate the large-scale penetration of renewable energy sources. In order to optimally exploit the operational flexibility of District Heating Networks, we introduce a novel mixed integer nonlinear formulation of the combined heat and power dispatch, accounting for pipeline energy storage. To cope with the computational complexity of this model we propose mixed integer second-order cone and mixed integer linear relaxations. The proposed models are implemented on a six-bus electricity and six-node district heating network.
