Abstrakt in Englisch
With the rapid development of power electronics, Flexible AC
Transmission Systems (FACTS) devices have been proposed and implemented
in power systems. This research mainly investigates the robust
coordinated control of FACTS devices and traditional power system
controllers in large power systems. The following objectives have been
achieved:
1. FACTS modeling and controller design: FACTS devices are modeled
using the current injection method. Linear and non-linear methods for
the FACTS damping controller design are developed. 2. Optimal choice
and allocation of FACTS devices: Using the genetic algorithms, the
locations of the FACTS devices, their types and rated values are
optimized simultaneously. The objective function, which consists of the
investment costs for FACTS devices and the generation costs, is
minimized.
3. Adaptive FACTS transient controller design using ANFIS technology:
This objective deals with the development of fuzzy adaptive FACTS
transient stability controller. Furthermore, by means of Adaptive
Network based Fuzzy Inference System (ANFIS) technology, the fuzzy
controller parameters are optimized.
4. Simultaneous coordinated tuning of FACTS damping controller and
conventional Power System Stabilizers (PSSs): Using the linearized
power system model and the parameter-constrained non-linear
optimization algorithm, interactions among PSS and FACTS damping
controllers are considered. The controller parameters are optimized
simultaneously to achieve a global optimal damping behavior.
5. Robust FACTS loop-shaping Power Oscillation Damping (POD) controller
design in multi-machine power systems: By applying the model reduction
and modern robust loop-shaping control technique, the FACTS robust
loop-shaping POD controller is realized. This controller exploits the
advantages of both conventional loop-shaping and modern H infinite
robust control technique. Moreover, it is a decentralized approach and
suitable for FACTS controller design in real large power systems.
