New Energy Cluster and Large-scale Power Grid Co-simulation Application based on RTLAB and CloudPSS

In view of the need for stability analysis of large- scale new energy cluster connecting to large-scale power grid system, the existing electromagnetic transient simulation tools have certain limitations. At present, there is a lack of simulation platform that can uniformly establish large-scale new energy and large-scale power grid models. Based on two different simulation tools, RTLAB and CloudPSS, a large-scale new energy cluster and large-scale power grid electromagnetic transient co- simulation platform is built. A new energy station equivalence method based on single machine representation method is proposed, and the accuracy of the equivalence method is verified by comparing with detailed station model, which provides a basis for the modeling of large-scale new energy clusters. On the other hand, the electromechanical - electromagnetic model conversion tool based on CloudPSS is introduced, which provides a method for large-scale power grid modeling. At last, the decoupling principle and hardware implementation scheme of co-simulation model based on RTLAB and cloudPSS are presented and the comparison of simulation results verifies the accuracy of the simulation platform.
