Strategy for Implementing Black Start and Islanded Operation Capabilities on Distribution System Level
Due to a change in load situation caused by the installation of decentralized generation plants accompanied by distinct advantages and disadvantages for grid operation, distribution system operators seek an advanced degree of supply autonomy. Embedded in an appropriate environment of controllable plants, storages and extended demand-side management using intelligent automation, local distribution systems can bear major faults of the transmission system, safeguard infrastructure in graded extent and facilitate supply restoration in the transmission system. Implementing capabilities of islanded operation, black start and crisis-resilience can be considered a comprehensive task concerning various areas of grid operation. Substantial fields of action are presented. Analysis has been conveyed in order to allow objectified contemplation. All considerations are based on factual data of a small distribution system operator (DSO).
