Power systems are complex structures that provide uninterrupted delivery of electrical energy to the consumer and are expressed as the sum of equipment operated in coordination with each other. However, in some cases, a complete or partial system collapse may occur in the power system. While this system blackout can sometimes be fixed immediately, sometimes it takes a long time to fix it. After long interruptions, social life, daily activities and production activities are interrupted; This leads to a huge financial loss. After a system blackout of the entire power system, elaborate power system restoration plans should be implemented immediately. The location and capacity of blackstart power generation units, which play a critical role in the restoration of the power system, are of great importance in deciding the restoration strategy to be applied after the system blackout. In this study, a simulation study was conducted using real data in order to understand the importance of power generation plants with recovery feature in the system restoration after the complete collapse of the power system. In this study, the behavior of power generation units during the application phases of system collapse and system restoration was investigated. Information is given about the points to be considered while preparing power system restoration plans.

“…One mainly discussed the function of the FCB unit and introduced field tests about it [10]. The other mainly studied how to use the FCB unit to accelerate the black start process of power systems [13,14]. However, as far as the authors know, there is no paper that has studied the dynamic response of the FCB unit under load rejection and black start process conditions.…”

Fast and reliable black start plays a key role in improving the ability of the power system to resist the risk of large-scale blackouts. For a black start with high voltage and long-distance transmission lines, it is much easier to cause phenomena such as self-excitation and power frequency/operating overvoltage, which may lead to black start failure and impact the reliability of the system's restoration. Meanwhile, the long time needed to crank up the non-black start units will impact the speed of the restoration. This paper addresses the advantages of using a thermal power unit with a fast cut back (FCB) function as a black start unit, and studies the transient process of the FCB unit during the restoration. Firstly, key problems in the power system black start process are analyzed and a practical engineering criterion of self-excitation is proposed. Secondly, the dynamic model of the FCB unit is presented. Thirdly, the field test of the FCB unit load rejection and black start is introduced, which is the first successful field test of black start with 500 kV long-distance lines in China Southern Power Grid (CSG). Finally, the transient process of this test is simulated using the PSCAD/EMTDC software, and the simulation results accord well with the field test results, which verifies the correctness of the FCB model and the self-excitation engineering criterion proposed.

“…The simulation work helps in the best way of loading the power plants and is applied for hydro power plant and steam power plant restoration [2]. The power system restoration problem involves so many factors like frequency monitoring, black start unit energization, transmission line energization and transformer energization [3]- [5]. Data Envelopment Analysis technique is used to evaluate efficiency of different types of Decision Making Units (DMUs) including transmission lines energization, performance evolutions of different electrical distribution utilities [6]- [8].…”

In this research work Radial Basis Function (RBF) Neural Network (NN) and Regression models are used to estimate Temporary over Voltages (TOVs) that are occurred during the reenergization of lightly loaded transformer. Assessment of the TOVs are carried out in order to control the high peak voltage up to a safe operating point to ensure the safety of the power system equipments. The proposed approaches are applied to the standard IEEE 30 bus test system to evaluate its efficacy. The statistical approach is applied to examine the robustness of the forecasting results. Results show that the methods conveyed in this research are better and could be helpful for power system restoration planning.
