Development of a Hybrid Simulator for Power System Analysis for a High Penetration of Distributed Generations

Abstract

SUMMARY Chubu Electric Power Co., Ltd.’s hybrid power system simulator consists of analog models and hybrid models. The power system facilities are downsized as an analog model, while the synchronous generators and the loads are modeled as an actual current source model through the amplifier and the digital model. In recent years, there is a growing interest in analyzing power system dynamic phenomena caused by a high penetration of distributed generations. Therefore, the multifunctional generator model that can simulate distributed generation has been developed.

Development of a Hybrid Simulator for Power System Analysis for a High Penetration of Distributed Generations

“…Thus, we developed new models and other elements for modeling distributed generators [3], and replaced the simulator with a new one provided with functions that enable power system analysis in the case of high penetration of distributed generators [4]. However, distributed generators have dynamic characteristics different from those of synchronous generators, which cannot be simulated by the existing models.…”
