Abstract
Despite all efforts toward minimizing power system outages, power system is still subjected to catastrophic failures. Power system restoration after complete shutdown is a critical decision process. Restoring the power system as fast as possible in secure and reliable manner is the main objective of power system restoration process as the prolongation and failures of this process lead to more economic and social costs. Power system build up strategy is one of the most practical restoration strategies that depends on restoring separated parts of system then interconnect them to restore the bulk system. Planning of this strategy involves several issues such as decomposing the network into number of independent islands and identifying the optimal restoration path sequence to restore each island. The restoration process includes building these subsystems and interconnecting them. After the system is subjected to complete shutdown, parallel restoration using the buildup strategy is an efficient way to speed up the restoration process. A new integrated restoration approach is proposed in this thesisthat investigate the smart grids new technologies such as on line monitoring and control using Wide Area Measurement System (WAMS) and the large embedded power inherent Microgrids (MGs)toreducecustomer interruption times.The main objectives of this thesis are:Develop An Integrated Approach For Power System Restoration Planning Automation in The PMU installed Power System consisting of :An approach to solve the Optimal PMU Placement problem (OPP) that makes the whole system completely observable.An approach to sectionalize the integrated power system into restorable islands achieving constraints for power system restoration.An approach to identify the optimal path to restore each island independently without violating restoration constraints.Develop AnApproach to Analyze the System Stability Online during Restoration Process Based On WAMS Propose AnApproach to Utilize Microgrids Capabilities during Power System Restoration.A MATLAB Simulation program is developed to represent a mathematical formulation of the proposed algorithm for restoration planning. The different proposed optimization processes are programed in one integrated package using MATLAB.The New England 39-bus power system is used to demonstrate the proposed approach and verify the results. The proposed method is also applied to the IEEE 118-bus system to prove approach capability and reliability in practical systems. The results are presented and evaluated.DIgSILENT software is used to study stability during restoration stages and to study the role of WAMS and Microgrids during restoration by modeling of the test systems. The modified New England 39-bus power system is used to apply the proposed approach and simulations are done on all islands. Generated power, picked loads, frequency, rotor angles and buses voltages are discussed to conclude the effectiveness of WAMS and MGs during restoration. The contribution of WAMS and MGs during restoration is discussed and evaluated.
