Design of precise simulation model of power converter of energy storage system located within micro-grids

摘要

In this paper, the modeling procedure of the bidirectional power converter for energy storage systems located within microgrids is being described. The aim was to develop simulation model with accurate behavior compared to experimental sample, due to implementation of the model within system-level simulations of complex microgrid systems. Simulations have been performed with PLECS circuit simulator. Also experimental sample similar to circuit topology of simulation model was realized within reduced power ration of the target application (1:10). Simulation models have been optimized based on laboratory findings to obtain the maximum degree of operating property precision possible. As a result of this approach, high-accuracy simulation models of DC microgrid systems can be created, allowing any operating scenario to be investigated at the appropriate power delivery.
