For the implementation of FACTS-Devices, especially for controllable transmission paths in an AC-system, intensive planning studies and redesign of control and protection systems have to be executed. Adverse control interactions with other controllers and a lack of optimization potential due to predefined devices have to be considered. Applying a control architecture, which enables the operation of a new FACTS-device and especially a controlled transmission path without affecting the rest of the system, can eliminate these problems. This non-intrusiveness is the key issue of the so-called Non-Intrusive System Control (NISC) architecture. In this chapter the basic requirements and structure of this new control architecture are described first. A second focus is given to the problem of controller interactions in abnormal operation situations where the NISC architecture helps to avoid malfunctioning or adverse reactions.
