“…These topologies can function as switching mode regulators to control and convert the DC output to a suitable utilization voltage. The DC output voltage depends heavily on the switching frequency of the PWM control signal .

“…For the DC‐DC converter, the currently used topologies are buck, boost, buck‐boost, Cuk, single‐ended primary‐inductor converter (SEPIC), and flyback converter . These topologies can function as switching mode regulators to control and convert the DC output to a suitable voltage, which depends heavily on the switching frequency of the pulse width modulation (PWM) control signal . Different switching controllers were recently presented to improve the performance of the DC‐DC converter.…”

Summary The use of photovoltaic (PV) systems has increased in recent years due to the high demand for clean energy sources. PV systems can utilize abundant and free energy from the sun, which is a substantial advantage. However, compared with other renewable technologies, the PV system still faces major obstacles such as high cost and low efficiency. In addition, fluctuating incident energy from the sun creates harmonics in the generated power that might lead to undesirable system performance. Total harmonic distortion (THD) is the ratio of distorted power to the main power of the signal, and is most commonly used to indicate the amount of signal distortion. THD has become a serious concern as more PV systems are integrated into grid systems. Previous research and reviews have attempted to reduce THD and its effect, but unfortunately focused on reducing THD at individual parts of the PV system. For the first time, this study holistically and systematically reviews the advances in THD reduction techniques for the entire PV system. The causes of harmonics, current solutions, and research gaps for further investigation are described in detail. Moreover, the current THD reduction techniques used in each stage of the PV system are compared, including their main benefits and drawbacks. Finally, this study recommends the use of adaptive filters as a possible solution for THD reduction because these filters have effectively reduced noise and disturbance in other systems.

Abstract:The aim of this study is to examine the possibility of using a stand-alone photovoltaic system (SAPVS) for electricity generation in urban areas in Southern Mexico. In Mexico, an urban area is defined as an area where more than 2500 inhabitants live. Due to constant migration from the countryside to the cities, the number of inhabitants of urban localities has been increasing. Global horizontal irradiation (GHI) data were recorded every 10 min during 2014-2016 in Coatzacoalcos in the state of Veracruz located on 18 • 08 09 N and 94 • 27 48 W. In this study, batteries represented 77% of the total cost, 12 PV panels of 310 W could export 5.41 MWh to the grid, and an inverter with an integrated controller and charger was selected, which decreased the initial cost. The city of Coatzacoalcos was chosen because the average annual temperature is 28 • , with an average relative humidity of 75% and an average irradiance of 5.3 kWh/m 2 /day. An emission factor 0.505 tCO 2 /MWh of greenhouse gases (GHG) were obtained, based on the power system, the reduction of net annual GHG would be 11 tCO 2 and a financial revenue of 36.951 × 10 3 $/tCO 2 would be obtained. Financial parameters such as a 36.3% Internal Rate Return (IRR) and 3.4 years payback show the financial viability of this investment. SAPVSs in urban areas in Mexico could be a benefit as long as housing has a high consumption of electricity.
