Hierarchical control - Smart transmission grids

The technological development and enhancement of new strategies related with Wide Area Measurement and Control Systems (WAMCS) is playing a key role with large interconnected power systems in order to assure stability under Low Frequency Oscillations (LFO). In this thesis a hierarchical intelligent controller scheme for multi-machine systems is presented with the purpose to maximise the damping factor of intra-area and inter-area oscillations combining the principles of Fuzzy Logic Control and aMulti-Agent Systems (MAS) architecture. The controller designing takes advantage of the controllability and observability definitions to obtain the optimal location of the local Power System Stabilizers (PSS) and the Phasor Measurement Units (PMU) where the local PSS has been modelled with fuzzy logic as well. An algorithm to measure the damping of any signal is developed and used as PMU measurement in the tie-lines. The time-domain response of the designed controller is tested in a power benchmark system demonstrating its adaptability and performance.
