Testbeds for integrated transmission and distribution networks: Generation methodology and benchmarks

Abstract

For future power systems with high penetration of distributed energy resources (DER), the coordination of the transmission system (TS) and distribution system (DS) is quite essential. In this paper, multiple testbeds that consist of various sizes of TS and DS models are designed for power flow (PF) and optimal power flow (OPF) analysis of the integrated transmission and distribution (TD) systems. Several benchmarks with characteristics for applications are proposed and their simulation results are presented in this paper. Researchers can use the testbeds designed in this paper to build their specific cases with published data, and they can also compare the results of their new approaches or algorithms with those obtained by the proposed benchmarks in this paper.
