Operation of extensive grid automation: Challenges on the example of voltage control

Abstract

Ongoing grid integration of flexible and decentralized generation and load produces various challenges, such as problems concerning the allowed voltage bandwidth. Grid automation functions are developed to handle these challenges using intelligent methods. These functions can be realized centrally, locally or distributed. To operate the resulting multitude of different solutions, it is necessary to document these including the corresponding requirements and dependencies. Using the example of the wide area voltage control (WAVC), existing description options are explained and their deficits are named. In order to avoid additional expenses due to a lack of documentation, a uniform format and procedure for documentation is proposed.
