Power quality issues produced by embedded storage technologies in smart grid environment

摘要

The advancement of new storage technologies is a powerful driver for a wide smart grids adoption by both electricity utilities and customers. However, the relative novelty of these technologies is posing a threat to their adequacy for electric distribution systems operation. In spite of the clear advantages brought by storage devices, such as fast response, reserve, resilience, fault ride-through capability and great help for electric system dispatchers, storage technology bears some disadvantages regarding early stage for deployment and power quality-related inadequacies. This paper addressed the issue of simulation studies for safe deployment of cutting-edge electricity storage technologies within electric distribution systems. The simulation results were assessed according with electric power quality standards, in order to build a comprehensive picture of the storage systems adequacy within smart grids.
