A hierarchical test benchmark of integrated energy system in Northeast China

To move from one-off restricted utilization of custom technologies upgrade to joint implementations at scale, demanding a recognized standard test benchmark for plausibility inspection. Therefore, the test benchmark of integrated energy systems (IESs) needs to exhibit generality and universality to adapt to and match the state-of-the-art research. The publicly available test benchmark developed in this paper consists of two levels: i) Local integrated energy system (LIES), which encompasses an electricity distribution grid and a primary heating network; ii) Community integrated energy system (CIES), which incorporates a microgrid and a secondary heating network in a campus. The database of the test benchmark stems from investigations and mirrors the physical assets of a real-urban energy system and takes into account the virtual deployment of future planning for wind power and hydrogen systems. LIES showcases key features of the IES located in a densely populated area, and CIES is a critical load encapsulated in LIES. The parameters and details of the database shared in the appendix involve cable impedance, pipeline parameters, electrical and thermal loads, etc., supporting independent access and the customized reconfiguration for the simulation and computation of emerging technologies. The practicality and validity are examined through the multiple instantiated basic energy flow calculations and myriad derivative calculations.
