The world has witnessed a substantial upsurge in energy demand in the recent decades, which has concurrently led to increased environmental contamination due to the use of carbon-based fuels to meet this demand. The increased pollution levels across the globe combined with the rapid depletion of these carbon-based non-renewable sources of energy has forced nations to adopt cleaner sources such as solar energy, wind energy, biomass etc. for meeting energy requirements. Utilities and power transmission companies, in several countries, have begun installation and operation of large-scale solar energy projects in order to augment the present electricity generation capacity. India has a tremendous potential for solar energy as 58% of the total land area receives an average solar insolation above 5 kWh/m 2 /day, annually. However, PV installations require proper economic formulation and technical modelling of PV plants. The study presented in this paper investigates the feasibility of installing a 1 MW grid-connected PV system in the arid climatic conditions of India. Four different regions of the Thar Desert: Barmer, Jodhpur, Jaisalmer, and Kalan Ghat have been considered for the study. A comparative study has been laid out based on energy yields, losses, and degradation of various module technologies namely Mono-Si, Poly-Si, CdTe, and CIS. The performance of the PV systems has been evaluated both in the fixed-tilt and variable-tilt configurations. Simulation results show that the daily yield in winter months ranges between 5.8 and 6.9 MWh/day whereas, during summer, it ranges between 5 and 7.1 MWh/day. The study suggests that CIS module is expected to produce highest annual energy yield of 2471 MWh with a PR of 86.1%, in the variable-tilt configuration for the Jaisalmer region. Annual energy loss due to temperature is expected to be highest for Mono-Si technology (14.4%) in the variable-tilt configuration and lowest for CIS technology (9.4%) in the fixed-tilt configuation. Moreover, mismatch losses for all the four technologies lie in the range of 0.1-1.1%.

“…The authors in [16] analyzed a system with PV + BES with a daily 6 h outage in a household located in Pakistan. In [17], short and frequent (2 h, 1800 times per year) power outages were simulated in a household in Iraq with PV + BES. In [18], the authors studied a residential load with PV + BES + DG having a 9 h power outage every day.…”

Recent natural disasters such as hurricanes Harvey and Maria have caused great disruption to the electric grid system. Additionally, government authorities have set ambitious goals to reduce greenhouse gas emissions. Thus, there is a growing interest in making the electric power systems more resilient while reducing their carbon footprint. In this work, we used HOMER Grid software to model behind-the-meter microgrids consisting of PV, battery, natural gas generator, and the electric load of an office building that consumes an average of 2 MWh per day. We varied the component sizes to determine the configuration with the lowest generator size to provide power during a two-day outage in the summer peak load. Environmental and economic analysis were performed to show the tradeoffs between different system design goals. The results indicate that installing a microgrid in an office building with a 600 kW PV array and 2.8 MWh lithium-ion battery can avoid the release of up to 287 tons of CO2 per year. The same microgrid configuration can endure a two-day blackout during the highest electric demand in the hurricane season without the need of a polluting backup generator. Microgrids will play an important role in the transition to a smart grid because they provide reliable power, make the system more grid-failure tolerant, and allow a high penetration of renewable energy into the electric grid which consequently reduces the environmental impact.

In this research, a standalone microgrid power system is proposed to electrify a small agricultural community in Palestinian territories. The load includes residential load and water pumping load. The community comprises about 30 households with some service buildings in addition to the water pumping system. The average load energy demand is 300kWh/day and the average power demand is 12.5kW, in the same context, the average energy demand for water pumping is 49kWh/day. The region has abundant solar radiation potential with a daily average of 5.4 kWh/m<sup>2</sup>. The optimum design was achieved using the HOMER Pro software. It took into consideration real incident solar radiation data, electrical demand profile for the community and water pumping system and market cost of all equipment. The optimization results showed that the best hybrid system among all feasible configurations is a PV system with an energy storage system combined with a diesel generator. The net present cost of the system is USD636,150 and the cost of energy (COE) produced is USD0.438/kWh. Sensitivity analysis is considered to study the impact of variations in PV cost, diesel fuel price, and maximum annual capacity shortages (MACS), the results showed that MACS has no effects. Energy management procedure is followed to reduce the excess electricity from 10.6% to 6.24% which in turn reduces the COE from 0.438 to USD 0.416/kWh.
