    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.

    Impact of Demand Side Management on Spinning Reserve Requirements Designation
    (International Journal of Renewable Energy Research, 2017) Tür, M.R.; Ay, S.; Erduman, A.; Shobole, A.; Wadi, M.
    The most important responsibility of power system operators is to ensure the reliability of the system. Protecting the load-generator balance is an important part of reliability. There are some uncertainties in the power systems in this regard. In Turkey, the fact that renewable (both solar and wind) penetration, changing peak loads and production results can change unexpectedly must be taken into consideration. The country has more difficulty in operating the energy system, so there is a greater need for system reserves to be created. The demand side needs to be well examined to ensure that the amount of reserves to be kept is at optimum cost. The socioeconomic parameters affecting this cost are added to the account and the minimum cost is created. For this reason, this study shows that the support reserves must maintain the required amount, depending on the demand side conditions.
