Abstract
Electric power systems are characterized by complicated operation due to different types of difficulties, such as repetitive disturbances and faults in addition to inherent sources of associated nonlinearities. Reinforcement of a power system can be achieved by enhancing the voltage profile, increasing the transmission capacity, etc. The utilization of Static Synchronous Compensator (STATCOM) achieves main targets such as improving power system transient stability, enhancing power system reliability, optimizing power system load flow and reducing transmission line cost. This thesis investigates the utilization of STATCOM to enhance the performance of the Egyptian Power System model (EPSM) based on Model Predictive Control (MPC) technique. Firstly, the optimal allocation of STATCOM in EPSM is identified using Particles Swarm Optimization (PSO). The objective is to minimize voltage regulation at candidate buses, maximize loading capability of critical transmission lines and minimize cost of the used STATCOM devices. Then, MPC technique is used with STATCOM to mitigate voltage sag in EPSM containing renewable energy resources. Finally, STATCOM is implemented based on MPC to mitigate unbalance in line voltages. The main objective is to evaluate the capability of the enhanced MPC state space model that can be applied in a general form for any power system. The proposed enhanced MPC state space model presented in this thesis is modified and adapted for mitigating unbalanced voltages at nominated buses. The effectiveness and validity of the proposed techniques are evaluated by extensive implementation of the developed algorithm on a large section of EPSM comprising 103˗buses. The proposed detailed STATCOM model based on MPC ensured its high capability to improve voltage transient response in both balanced and unbalanced voltage modes in addition to participating in mitigating voltage unbalance in EPSM. Results of the two proposed MPC models are discussed based on the optimal allocation of STATCOM in EPSM.
