(Mdpi, 2025) Tür, Mehmet Rıda; Aydogmus, Zafer; Tur, Mehmet Rida; Department of Electricity and Energy / Elektrik ve Enerji Bölümü
This manuscript aims to increase the utilization of solar energy, which is both environmentally friendly and easily accessible, to satisfy the energy needs of developing countries. In order to achieve this goal, maximum power generation should be provided from photovoltaic panels. Several maximum power point tracking (MPPT) methods are utilized for maximum power generation in photovoltaic panel systems under different weather conditions. In this paper, a novel intelligent hybrid fuzzy logic-controlled maximum power point tracking algorithm founded on the perturb and observe (PO) algorithm is presented. The proposed fuzzy logic controller algorithm and the incremental conductivity maximum power point tracking algorithm were simulated in a MATLAB(2018b version)/Simulink environment and evaluated by comparing the results. Four Sharp ND-F4Q295 solar panels, two in series and two in parallel, were used for the simulation. In this study, the voltage ripple of the proposed hybrid method was measured at 1% compared to the classical incremental conductivity method, while it was 8.6% in the IncCon method. Similarly, the current ripple was 1.08% in the proposed hybrid FLC method, while the current ripple was 9.27% in the IncCon method. It is observed that the proposed smart method stabilizes the system voltage faster, at 25 ms, in the event of sudden weather changes.

(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2018) Tür, Mehmet Rıda; Tur, Mehmet Rida; Padmanaban, Sanjeevikumar; Ay, Selim; Khan, Imtiaj; Department of Electricity and Energy / Elektrik ve Enerji Bölümü
This paper discusses the power quality issues for distributed generation systems based on renewable energy sources, such as solar and wind energy. A thorough discussion about the power quality issues is conducted here. This paper starts with the power quality issues, followed by discussions of basic standards. A comprehensive study of power quality in power systems, including the systems with dc and renewable sources is done in this paper. Power quality monitoring techniques and possible solutions of the power quality issues for the power systems are elaborately studied. Then, we analyze the methods of mitigation of these problems using custom power devices, such as D-STATCOM, UPQC, UPS, TVSS, DVR, etc., for micro grid systems. For renewable energy systems, STATCOM can be a potential choice due to its several advantages, whereas spinning reserve can enhance the power quality in traditional systems. At Last, we study the power quality in dc systems. Simpler arrangement and higher reliability are two main advantages of the dc systems though it faces other power quality issues, such as instability and poor detection of faults.

(IEEE, 2022) Çakmak, Fevzi; Oymak, Aysenur; Altun, Muslime; Tür, Mehmet Rıda; Cakmak, Fevzi; Atic, Serdal; Tur, Mehmet Rida; Bayindir, Ramazan; Department of Electricity / Elektrik Bölümü; Department of Electricity and Energy / Elektrik ve Enerji Bölümü
Distributed generation systems are needed in order to use existing energy resources efficiently and to meet energy needs. Although the interconnection of distributed generation systems with renewable sources offers many advantages, technical difficulties may arise from the inappropriate integration of distributed generation. Therefore, optimal planning of distributed generation is very important for the distributed grid to provide the expected power. Optimizing production systems is used to increase efficiency, provide flexibility in electrical systems, reduce costs and reduce power fluctuations. Meta-heuristic algorithms are more suitable for multi-purpose applications. In this study, the renewable energy source and energy storage system in the distributed generation system are also mentioned. Some of the optimization methods used for optimal planning of the distributed system are also included.

Effect of Faults in Solar Panels on Production Rate and Efficiency
(IEEE, 2018) Tür, Mehmet Rıda; Colak, Ilhami; Bayindir, Ramazan; Department of Electricity and Energy / Elektrik ve Enerji Bölümü
The economic life of Solar Power Plants (SPP) is accepted for more than 20 years and this point is taken into account in financial analysis. The cumulative effect of very small changes in the efficiency of a system that will generate energy for 20 years increases significantly over the years. SPP efficiency determines the losses in the generated energy. The failures in SPPs have a serious impact on the reliability of the system and the energy balance. Because of this, the energy losses produced by the SPP plant directly depend on two major factors. These factors are plant failures and production inefficiencies in photovoltaic (PV) panels. To know the negative impact of energy losses in PV plants, contributes to optimization in maintenance and design and increases efficiency in power production. In this study, probable losses in SPPs are classified and examined and the possible consequences of these losses and their effects on SPP performance are explained. In addition, by using the actual data in the operation and maintenance follow-up of many power plants, error rates grouped by the deficiencies in energy balance are achieved. According to these results, the process in the system under test, 67415 MW of power plant and 59211 MW of power plant has been obtained, resulting in a total 87.83 percent difference.

Effects of distributed generations' integration to the distribution networks case study of solar power plant
(İlhami Çolak, 2017) Tür, Mehmet Rıda; Baysal, Mustafa; Wadi, Mohammed; Tur, Mehmet Rida; Department of Electricity and Energy / Elektrik ve Enerji Bölümü
All over the world, the Distributed Generations (DGs) integration to power system has increased in the recent years due to economic, environmental and technical advantages. Turkey which has the huge solar potential has focused on integrating both licensed and unlicensed solar power plants by providing 10 years of purchasing guarantee as an incentive for the electricity producers from solar energy. However, the integration of DGs has several negative effects on the distribution networks (DNs). This work is concerned with investigating the possible challenges that may arise due to integration of PV based DGs on the existing distribution networks. Short circuit current level with respect to variation in MW integration is studied for the case the utility network is weak and strong. When the utility network is strong, the integration effect of inverter based DGs like solar power plants were observed insignificant. However, for the weak utility networks, the integration of inverter based DGs has been observed to have significant influence. Finally, directly integrated DGs (without inverter) are considered to reveal its difference with the non-inverter based DGs. As the case study, the distribution network integration of a solar power project, which is found in the Antalya region of Turkey, is investigated. This is 12 MW solar power plant designed to be connected to the local distribution network in Antalya. It is concluded that the effects of directly integrated DGs are observed more prominent compared to the inverter based DGs. DigSILENT Power Factory simulation tool is used for the study.

Impact of Demand Side Management on Spinning Reserve Requirements Designation
(Int Journal Renewable Energy Research, 2017) Tür, Mehmet Rıda; Ay, Selim; Erduman, Ali; Shobole, Abdulfetah; Wadi, Mohammed; Department of Electricity and Energy / Elektrik ve Enerji Bölümü
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.

(Ieee, 2018) Tür, Mehmet Rıda; Wadi, Mohammed; Shobole, Abdulfetah; Ay, Selim; Department of Electricity and Energy / Elektrik ve Enerji Bölümü
Demand for electricity is constantly increasing day by day. The biggest challenge is to provide uninterrupted and high-quality electricity to customers in variable conditions. To accomplish this, the two parameters must always be checked for each condition; these parameters are load distribution and network frequency. In this study, fuzzy logic and Proportional Integral Derivative controller method is applied in power system connected with two different fields to remove the fluctuations of electric energy. For this, MATLAB offers simulation applications and models in Simulink. Both different control directions are compared according to the results obtained. To emphasize the effectiveness of the proposed fuzzy control system, two field-connected power systems were simulated in four scenarios in a wide range of operating conditions. In addition to all these, the performance of the proposed method is compared with a Proportional Integral Derivative tester with simulation studies and the results show the effectiveness and superiority of the proposed approach.

Protection Coordination Practices for Industrial Ring Distribution Network Case Study of Organized Industrial Zone (GEBZE, Turkey)
(IEEE, 2018) Tür, Mehmet Rıda; Baysal, Mustafa; Wadi, Mohammed; Tur, Mehmet Rida; Department of Electricity and Energy / Elektrik ve Enerji Bölümü
The traditional distribution networks are mostly radial. Radial networks are easy to implement and operate, but it introduces a great challenge concerning electricity supply reliability. In organized industrial zones, the unplanned energy interruptions can cost a lot, as industrial loads are always working. Consequently, distribution networks are mostly implemented as a ring network. The ring distribution network improves the electricity supply reliability. However, compared to the radial networks, the application of ring network introduces its own technical challenges such as increased short circuit current during the fault, difficulty in protection coordination, increased rating capacity of each equipment and increased investment cost. In this paper, the protection coordination technique that is used in an organized industrial zone will be discussed. In the ring distribution network, differential relays, which rely on communication between the protection relays, are used for the underground cable protection. To guarantee cable protection when communication is failed, an auxiliary protection by using directional overcurrent relays is used. In this paper, the protection coordination study for the GEBZE organized industrial zone, which is available in Istanbul, Turkey, is conducted by using state of the art methods. The results of the study are verified by applying to ABB relays, which are available on the organized industrial zone's site under study.

Reliability Evaluation in Smart Grids Via Modified Monte Carlo Simulation Method
(IEEE, 2018) Tür, Mehmet Rıda; Baysal, Mustafa; Shobole, Abdulfetah; Tur, Mehmet Rida; Department of Electricity and Energy / Elektrik ve Enerji Bölümü
Operation of closed-ring power distribution systems has various advantages over both meshed-operated and radially-operated systems. Closed-ring system unlike to radial system, the voltage drop is less, achieves high reliability of power on demand since the power is supplied from both ends, and reduces the voltage fluctuation in high loaded areas by using a tie power line. However, the reliability assessment of closed-ring power grids is not a trivial task. Monte Carlo Simulation (MCS) is one of the most famous methods to assess the availability of any power system. However, the most proposed methods are able to evaluate the reliability of radial and open-ring grids. This paper developed the best known MCS method to assess the reliability of closed-ring grids by integrating the total loss of continuity (TLOC) definition into the MCS. The developed method is called modified Monte Carlo Simulation (MMCS) method. The MMCS is tested by using Roy Billinton Test System (RBTS) buses 2 and 4. The obtained results confirm the correctness of the proposed method. Therefore, MMCS method is appropriate to assess the reliability of both simple and complicated closed-ring systems.

A Review of Active Power and Frequency Control in Smart Grid
(Ieee, 2019) Tür, Mehmet Rıda; Bayindir, Ramazan; Department of Electricity and Energy / Elektrik ve Enerji Bölümü
Frequency and actual power control in energy systems are of great importance in grid control depending on time. The frequency of the system is fixed on the basis of the balance of production and consumption, depending on the actual power balances. Because the frequency is a global value, a change in power demand at a point in power demand is directly affected by the system. But the power system grid currently used was designed around centralized power generation and one-way supply of power deliver to customer to fulfil the basic electricity need. This system is aged and struggle to maintain the frequency of a system. However, in the modern grid model, information flow between producers and consumers is provided in two ways and this communication provides efficient planning. In this study, more efficient and reliable new technologies are searched in order to provide quality energy in smart grid. This review article discusses a frequency and active power control mechanism to ensure the balance between the supply network of the network-intelligent system.

Valuation of Reliability Assessment for Power Systems in Terms of Distribution System, a Case Study
(Ieee, 2017) Tür, Mehmet Rıda; Shobole, Abdulfetah; Wadi, Mohammed; Bayindir, Ramazan; Department of Electricity and Energy / Elektrik ve Enerji Bölümü
Supplying electrical energy to the load on demand, economically and with acceptable levels of reliability and service quality is the main task of a distribution system. Energy distribution reliability is important in the competition conditions in electricity markets because consumers directly supply energy. Therefore, it is not enough to estimate how reliable the distribution system is at present and to estimate the future reliability change in order to make optimum planning decisions, but also to provide the necessary amount of spinning reserve. The past reliability performance of distribution system can be quantified using a wide range of indices. This study is concerned with evaluating the reliability indices for only part of a network. Even though this study is limited due to unavailability as well as the inaccessibility of full and correct data over a sufficient period for analysis, it can give a clue and motive for further evaluation of the reliability of network.
