Due to the growing use of Renewable Energy Sources (RES) in many countries, the need for an accurate and detailed analysis from the technical and economic view point seems to be necessary. Power Quality (PQ) can also be another considerable matter that needs to be carefully evaluated. In this regards, in this article, an analytical and detailed approach is presented to evaluate the technical and economic performance of the strategy for PQ changes. In addition, an optimization-based PQ change strategy is presented to provide a distinct PQ in integrated grids with renewable generations. The proposed strategy is based on the assessment of financial losses due to changes in the quality of power and the cost estimation of various reduction approaches and repayment solutions. This approach presents various customer requirements and various levels of PQ in the power grid. In order to evaluate the performance of the proposed method, the effectiveness of the presented model has been utilised in an actual case study, and the results have been obtained and analysed. The results of the simulation provide both technical and financial advantages to obtain optimal change strategy.

“…Adefarati et al [14] have presented the benefits of using renewable energy sources for reliability, environment and economics parameters like cost of energy, life cycle cost, the annual cost of load loss and life cycle greenhouse gas emission cost. Razmjoo et al [15] have performed technoeconomical analysis for combined utilization of solar, wind and diesel energy for supplying selected load of Semirom city of Iran and presented economic viability of renewable energy use. Kumar et al [16] have designed a hybrid standalone Wind-PV-Battery system to supply electricity for technical university campus located in north-west Indian state Rajasthan and found that optimal generation unit price is compatible with grid extension case.…”

Remote area electrification is a major concern for a government of any developing nation. India is also working for it but despite continuous efforts towards remote area electrification, several thousand households in India are un-electrified. Several schemes have been launched by Government for electrification of such areas through grid extension but still many areas have not been covered under the proposed schemes due to economic, environmental and geographical reasons. Narayanpur district in Chhattisgarh state of India has un-electrified regions and various issues like poor literacy, untreated water facility and lack of access to communication networks. In order to find viable option of electricity supply to this region, a case study has been performed for the feasibility of off-grid floating photovoltaic (PV) system, on-ground PV system and grid extension along with their comparative analysis with respect to certain parameters i.e. net present value (NPV), cost of energy (CoE), environment cleanliness and social acceptance. Floating PV and onground PV systems have been designed and simulated using System Adviser Model (SAM) software developed by National Renewable Energy Laboratory (NREL), USA. The results show that floating PV system has lowest CoE of $0.0598/kWh and least negative NPV of $185,431 as compared to other two options. However, it is found that floating PV system achieves positive NPV of $38,968 in 28th year of project life.

“…The techno-economic analysis for grid-connected and off-grid systems at different cities at the Arabian Peninsula and KSA using a combination of HRES such as PV, wind turbine, fuel-cells, and battery were provided in [15][16][17][18][19][20][21][22]. The authors in [15] reviewed the recent control strategies for energy management in hybrid renewable energy system.…”

“…The paper concluded that the PV/diesel/battery hybrid configuration is found as optimum configuration with better performance in fuel consumption and a reduction in CO 2 emissions. Another study in [18] implemented economic and technical analysis of solar-wind and diesel system. The study concludes that the optimum hybrid system could generated a required energy and reduce greenhouse emission by integrating 15 kW PV array, 2 wind turbines, 1 kW diesel generator, 13,603 kW of battery, and 1 kW converter.…”

This study presents a detailed feasibility analysis of technical and financial assessment for grid-connected Hybrid Renewable Energy System (HRES) configurations by including grid-only, HRES-only and grid-HRES at four different provinces in the Kingdom of Saudi Arabia (KSA), namely; (Al Baha University, University of Jeddah, Prince Sattam Bin Abdulaziz University, and Tabuk University). The objective of this paper is to search the possibility of supplying the load demand with the optimum system that has the lowest net present cost (NPC) and greenhouse emission CO2. The simulation results show that NPC of a proposed grid/PV system, at the current grid’s tariff, is more sufficient than other configurations with a result in a renewable fraction of more than 50%, a payback time of 17 years, and 54.3% reduction in CO2. The results also show that the integration of 62 kW PV array with the main grid is the best configuration that leads to the minimum cost of energy (COE) of 0.0688 $/kWh and the sell back energy of 9.16% of total energy consumption at Al Baha University. Besides, optimization modeling addresses that HRES-only system can supply the full load demand without power shortage (<0.1%) with a major contribution from solar PV by 78.5%, wind energy shares 11.3% of load demand, and 10.2% from battery banks. The developed analysis concludes that the objective function is feasible for the selected locations. The study has three novelties. Firstly, the required load at different locations of the university’s buildings at KSA is supplied by minimizing COE. The objective function is achieved by considering a combination of HRES. Then, it applies the sensitivity analysis for several cases such as payback time, gird’s tariff variation, and load demand change. Finally, the current analyses are applicable to any university at KSA and around the world.
