Real-Time Models of Advanced Energy Conversion Systems for Large-Scale Integration Studies

摘要

Future grids will present a much more distributed power system with high levels of power electronics-based generators. Under this scenario, new methods, algorithms and strategies should be thoroughly analyzed, compared and validated to ensure the reliability of power systems. Furthermore, proper models with reasonable balance between detail and simplification are required to represent the behavior of these components. Real-time models allow to reproduce transient behavior of power electronics faithfully and in a reasonable timeframe. This work presents EMT real-time models of advanced energy conversion systems including: i) Type-III and -IV wind power generation systems, ii) photovoltaic power plants, and iii) battery energy storage systems. Transient simulations have been undertaken to illustrate the performance of each model when connected to an infinite bus. Moreover, the models have been included in the Simplified Australian 14-Generator test system as an example of large-scale renewable and energy storage integration.
