Feasibility analysis of grid-connected and islanded operation of a solar PV microgrid system: A case study of Iraq

Iraq has massive potential for electricity generation from solar energy. Because the country currently suffers from daily electricity shortages, a grid-connected PV system is an unsuitable option since the PV cannot serve the load during the electricity blackouts. This paper aims to analyze the techno-economic and environmental feasibility of a solar PV microgrid system which is able to supply the load during both grid availability and outage periods. A household in Baghdad was selected as a case study. HOMER software was used to carry out the overall analysis using five different control strategies. The results indicated that the most economical configuration was achieved by allowing the grid to charge the batteries at all rates, with a net present cost (NPC) of $29,713. A sustainability assessment revealed that preventing the grid from charging the battery resulted in the highest renewable fraction and the lowest CO2 emissions with 64.9% and 4533 kg/year, respectively. Furthermore, inserting a diesel generator to an economically optimized system was found to reduce the NPC by 11.6%, while increasing the CO2 emissions by 32.7%. This study showed that implementing this sort of project can provide clean, economical, and continuous electricity production in countries with daily blackouts.

Output voltage control of dual input single ended primary inductor converter (SEPIC) for hybrid photovoltaic-piezoelectric system

2017-07-01 , Yong H.Y. , Nurul Izni Rusli , Mohammad Faridun Naim Tajuddin

Renewable sources are developing fast and widely used to reduce the non-renewable sources. In this paper, a standalone, portable, green energy dependent, dual input SEPIC converter is developed with a 12 V DC output voltage The control strategy for this converter is designed to retain output voltage within 12 V when inputs source is in the wide range of 6V to 24V. Sharing only the output capacitor method is one of the multi-input method and has been used to combine two input energy which are solar and vibration in this research. This system contains feedback system and is designed by using Proportional Integral Derivative (PID) controller to ensure the output voltage is 12V. The converter with the controller has no overshoot, it settling time is about 0.02 second and the rise time is about 0.0001 second. Thus, it is proved the converter with controller is capable to reduce the settling time and rise time compare to converter without controller.
