The rapid population of the distributed PV systems brings concerns about system reliability and voltage quality of the power systems. This paper aims to evaluate the effects of those plants to the voltage quality and system reliability of power systems. The paper develops a statistical analysis method by developing metrics for a photovoltaic power plant located in Ankara, Turkey, using power generation data. The generation data involves all uncertainty associated with weather conditions as well as environmental factors. Therefore, it provides a complete statistical analysis of the feasibility of photovoltaic systems at the considered region, and hence its effects to the voltage quality. The study is conducted using historic data gathered from the photovoltaic system located at the Department of Electrical and Electronics Engineering of Middle East Technical University. To validate the obtained results, reliability and voltage quality of the generation is investigated in simulation environment. The results are assessed using voltage regulation and flicker as considered metrics.

Evaluation of Grid-Connected PV Converter Power Module Technologies in Terms of Efficiency, Initial Cost, and Return on Investment Time Oztoprak, Oguzhan; Hava, Ahmet Masum (2019-01-01) The voltage source converter (VSC) of the grid connected photovoltaic (PV) systems is the most technological component in a PV system and contributes to 5-15% of the whole investment. As the cost and energy efficiency of a VSC are two factors that determine the total system economics, the system total cost of ownership (TCO) should be optimized during the VSC design. This paper provides a design methodology for grid connected VSCs considering TCO, the return on investment (ROI) and payback period (PP) as th...
A New Index for Voltage Quality Assessment at Distribution Systems KARACELEBİ, Mert; ERCİN, Özden; Göl, Murat (2018-09-07) Analysis of power quality problems in distribution systems is getting important day-by-day because of the increase in vulnerable non-linear loads, such as data centers across the Globe. Regulatory authorities all over the world investigate these problems in order to serve in better conditions to the users. In this article we analyzed power quality problems in terms of their effects to the users, and developed an index to observe the problematic areas. As different types of loads in terms of operation critic...
Evaluation of Photovoltaic Systems For Reactive Power Compensation In Low Voltage Power Systems Uğur, Mesut; Duymaz, Erencan; Göl, Murat; Keysan, Ozan (2018-10-25) The four-quadrant operation ability of photovoltaic (PV) inverters makes them promising candidates for reactive power compensation in low voltage systems. In this paper, utilization of PV inverters instead of conventional reactive power compensation units is evaluated. The use of PV inverters for reactive power compensation as well as active power supplying is investigated considering a real life system. The considered system suffers from low capacitive power factor due to the connected online UPS system. T...
Implementation of 1 kV on LV feeders: a smart alternative to MV line investments to solve voltage drop problems at LV systems OZENA, Kadir; CEBECI, Mahmut E.; TOR, Osman B.; BATAR, Gokhan; KILIC, Andac; TURKMEN, Ulfet; Güven, Ali Nezih (2017-04-21) This paper presents methodology and on-site pilot implementation of utilizing 1 kV at low voltage (LV) feeders as an alternative to medium voltage (MV) line investments to solve voltage drop problems at LV systems. Typically distribution companies solve voltage drop problems of LV system by installing a new MV/LV transformer and transferring outmost loads of the existing transformer to the new transformer. This necessitates installation of MV line between the existing and new transformer. The implementation...
MAXIMUM POWER POINT TRACKING FOR LOW-POWER PHOTOVOLTAIC SOLAR PANELS BODUR, M; ERMIS, M (1994-04-14) A maximum power point tracker unit is developed for the optimum coupling of photovoltaic panels (PVP) to the batteries and load through a controlled DC-DC power converter (chopper). The system consists of three main units: (i) the photovoltaic panels that convert solar power to electricity; (ii) a chopper which couples the power of PVP to the load or batteries at a constant voltage; and (iii) maximum power point (MPP) computing unit that determines the set point of the chopper to keep the panel voltage at a...
