    An Education Set for Solar Cell Models
    (Düzce Üniversitesi, 2013) Yavuz, Ayhan; Başol, Derya; Ertay, M. Mustafa; Yücedağ, İbrahim
    It is well known that solar energy is renewable energy source and also it is the origin of renewable energy types. The solar energy is constantly and can be used in the desired each geographical area; therefore, the importance of using this energy increases in production of electrical energy with each passing day. In this study, the equivalent electrical circuit models of the solar cells and equations of these models were given. Using these equations the equivalent, circuit models were designed in Matlab Simulink program. To examining the characteristics of the circuits an interface was designed in Matlab GUI environment. With designed interface circuit characteristics and graphics of the circuits can easily obtained and analyzed.

    AN APPROACH FOR DESIGNING PASSIVE POWER FILTERS FOR INDUSTRIAL POWER SYSTEMS BY USING GRAVITATIONAL SEARCH ALGORITHM
    (Univ Osijek, Tech Fac, 2015) Tosun, Salih; Öztürk, Ali; Ertay, M. Mustafa; Yalçın, Mehmet Ali; Zengin, Ahmet
    Harmonics are one of the important factors in determining the energy quality in power systems. Hence, eliminating or damping undesired harmonics is crucial in electrical power systems. Due to their low costs, Passive Power Filters (PPF) are widely used in industrial power systems to limit harmonics' undesired affects. In this study, a new approach to design a PPF for power systems using heuristic Gravitational Search Algorithms (GSA) is proposed. Traditional Try and Error (TAE) method is, first, utilized to eliminate harmonics in our model power system. Then, GSA is adopted to minimize the effective current value of Point of Common Coupling (PCC) in the same model system. Our results yield that our proposed method with GSA eliminates the harmonics effectively.
