Economic Dispatch of AC/DC Power System Considering Thermal Dynamics

Advance in renewable penetration has promoted the interaction between AC and DC power system multi-energy sources. However, disparate nature of different energy utilization technologies presents strong challenges for economic dispatch such a complex system. This paper proposes comprehensive characterization AC/DC considering integration. Detailed models are elaborated grid, district heating (DHS), coupling units, renewables to describe their inner interactions accurately. On this basis, an method is developed minimize operation cost renewable’s abandonment. Simulations indicate that systems sources can enhance voltage levels improve operational economy.
