Creating Multi-timescale Digital Twin Models for Regional Multiple Energy Systems on CloudPSS

With the rapid development of the electricity market and energy internet, it is vital to provide an effective path to improve the comprehensive utilization ratio of energy for regional multiple energy systems (RMES). In this paper, the definition of RMES and the necessity and feasibility of building digital twin models for RMES are introduced. Then, a solution for creating the digital twin models for RMES on CloudPSS is provided. The digital twin models are based on the power flow and electromagnetic transient (EMT) models in order to fulfill different analyzing requirements. Finally, The IEEE-13 test system and a photovoltaic test system are built to validate the performance of the digital twin models. The power flow and EMT simulation can be rapidly calculated and the results show the effectiveness and practicability which can be used for system parameter verification, abnormal device awareness and optimized operation to ensure the safety and stable operation of the RMES.
