Calculation Of Optimal Value Of Spinning Reserve Requirement For Unit Commitment İn Power Systems By Considering Lost Parameters;
(Gazi Universitesi Muhendislik-Mimarlik, 2019) Tür, M.R.; Ay, S.; Shobole, A.; Wadi, M.
Spinning Reserve is one of the most important sources used by system operators in response to unforeseen events such as generation discontinuities and sudden load changes. It is possible to maintain the power system against production interruptions caused by unforeseen circumstances, which can be caused by keeping the amount of reserves to be used high, in case of this process the possibility of applying the load shed decreases, but in this case reserve supply results in a very high cost. If the amount of reserves is kept low in order to reduce the cost, there will be an energy that can not be provided in the case of possible interruptions and failures, and the consumers may be left without electricity. There is a need for an economical review of these two situations in a balanced way. In this study, the requirements of the Spinning Reserve needed in the power system are determined by taking into consideration socio-economic parameters such as the amount of expected energy not supplied and value of lost load. These parameters, which are added to the cost function, are calculated for the first time in our national power system by a new method. Macroeconomic analysis has been supported for this value. Thus, considering the calculated socioeconomic parameters, a program based on benefit/cost is used to calculate the economic cost value of the reserve for the power system model. © 2019 Gazi Universitesi Muhendislik-Mimarlik.

Protection Coordination in Electrical Substation Part-2 Unit Protections (Differential and Distance Protection)-Case Study of Siddik Kardesler Substation (SKS), Istanbul, Turkey
(Gazi Universitesi, 2017) Shobole, A.; Baysal, M.; Wadi, M.; Tür, M.R.
Power systems must be protected against faults to ensure quality and reliable generation, transmission and distribution of power systems. Power system protection is provided by the protection relays. This paper is the second part of the Protection Coordination study for the Siddik Kardesler Substation. The protection for transmission lines, transformer, bus bars and customer feeders is provided by overcurrent protection, differential and distance protection schemes. In this paper, issues related to the Differential Protection and Distance Protection for the substation will be discussed. Finally, the test and commissioning have been conducted and the substation is successfully energized without a problem. © 2025 Elsevier B.V., All rights reserved.

Protection Coordination Practice in Electrical Substation Part-1 Overcurrent and Earth Fault Protection - Case Study of Siddik Kardesler Substation (SKS), Istanbul, Turkey
(Gazi Üniversitesi, 2017) Shobole, A.; Baysal, M.; Wadi, M.; Tür, M.R.
Protection coordination is the heart of all power systems. To ensure a quality and reliable operation of the power systems, an electrical fault must be cleared within a short time. This can be achieved by proper coordination between the protection relays. In Siddik Kardesler Substation the MV voltage feeders’ protection is provided by overcurrent relays. This paper is principally concerned with practical protection coordination of the electrical substation by using Siddik Kardesler Substation substation as a case study. In the Part-2, distance and differential protection will be discussed. Finally, after test and commissioning, the substation is successfully energized without a problem. © 2017, Gazi Universitesi.
