Article Citation - Scopus: 1The Distribution of Wind Power from a Dispersed Array of Wind Turbine Generators and Its Reliability Based Applications(Elsevier, 2026) Eryilmaz, Serkan; Kan, Cihangir; Devrim, YilserIn this paper, the probability distribution of wind power from a dispersed array of wind turbine sites is studied considering forced outage rates of wind turbines. The wind speeds at distinct sites are assumed to be dependent and the dependence is modeled by copulas. In particular, the probability distribution of the aggregate power from two sites is exactly derived. The probability distribution of the aggregate power is also derived under the particular case when site 1 consists of n1 identical wind turbines of type 1 and site 2 consists of n2 identical wind turbines of type 2. Numerical results are presented to illustrate the theoretical findings for a chosen copula function.Review Citation - WoS: 83Citation - Scopus: 92A Review on the Development of the Electrochemical Hydrogen Compressors(Elsevier, 2021) Durmus, Gizem Nur Bulanik; Colpan, C. Ozgur; Devrim, YilserHydrogen should be stored at high pressure and high purity, especially when utilized in fuel cells. Conventionally, mechanical compressors are used for pressurization of hydrogen; however, this technology has disadvantages such as noise and vibration during operation due to their moving parts. Electrochemical hydrogen compressors (ECHC) have emerged as an alternative solution, as these devices can purify and compress hydrogen electrochemically in a single device. This review provides a comprehensive overview of key components and management strategies of the ECHC systems. This review will also provide an overview of different hydrogen compression technologies and provides a comprehensive overview of the latest developments and current issues and future of ECHCs. For this purpose, firstly, the advantages and disadvantages of ECHC compared to mechanical compressors are explained. Then, recent studies on hydrogen purification methods are given. The working principle of ECHC, material development studies and mathematical modeling of ECHCs are also discussed.
