Optimal Scheduling of Virtual Power Plant Considering Reconfiguration of District Heating Network

A combined heat and power virtual plant (CHP-VPP) can effectively control the distributed resources in an electric–thermal coupling system solve problem of lack flexibility caused by large-scale renewable energy grid connection. Similar to optimal reconfiguration distribution network topology operating switches, district heating is also equipped with tie sectionalizing valves realize adjustment (DHN) topology, which provides economical effective method for improving system’s flexibility. Based on this, this paper proposes a CHP-VPP economic scheduling model considering reconfigurable DHN. Firstly, flow introduced reduce computational complexity. Secondly, adaptive robust optimization solved column-and-constraint generation algorithm used settle randomness wind ensure that results are feasible all worst scenarios. Finally, feasibility proposed illustrated case studies based actual CHP-VPP. The show compared reference case, reconfigurability DHN process cost about 2.78%.
