Hierarchical control of interconnected power systems
The demand for a new control policy to improve dynamic performance of large interconnected power systems is becoming very essential. Although the dynamic subsystems (comprising an interconnected power system) may be individually stable, the overall system stability may suffer as these subsystems interact. Among all recently developed control approaches, the hierarchical control policy has the potential of being the most suitable and promising and provides a simplified, feasible solution for large interconnected system problems. In such an approach, the large system is decomposed (along its weak interaction boundaries) into simpler subsystems. The solution of the large system problem is obtained by individually solving each subsystem (assuming fixed interaction with other subsystems) and coordinating these individual solutions to account for the changes in the assumed interaction. Multilevel decomposition and multilevel coordination require multimodeling with different levels of details. Examples of multimodeling are illustrated. Moreover, methods to design hierarchical coordinators at various system levels are developed. Upon application to several existing power systems, the hierarchical control methods have shown very promising results in improving the power system's overall dynamic performance, and are reliable and economical.
