“…The comparison is made by using the COE generic to the optimal operation of the power system which is shown in Table 4. It well established that the COE derived from the present study is lower than the one got in [9, 32–37]. Hence, the optimisation technique presented in the paper has resulted in a cost‐effective design to reduce the techno‐economic costs that are associated with the proposed microgrid system when compared with the configurations found in literature.…”

The universal power demand is increasing every day because of population growth, industrial revolution and high standards of living. The renewable energy technologies (RETs) are environmental and cost‐effective solutions to satisfy dynamic load profile based on the application of multiple components of a standalone microgrid system that encompasses photovoltaic (PV), diesel generator (DG), electric storage system and wind turbine generator (WTG). This study reveals more insight into various research questions that have not been completely addressed in past investigations. The contributions of the study are expressed: (i) analyse the effects of RETs on the total cost, (ii) test the total benefits, (iii) estimate the market benefit share of the unit that reflects the benefit of one generation unit in proportion to the whole power system, (iv) maximise and minimise the yearly average power generated by (PV and WTG) and DG. This research work presents the application of fmincon optimising tool to accomplish the objectives of the study owing to some significant characteristics. The outcomes of the work show the validity of the model and can assist the utilities to minimise the costs that are identified with the optimal operation of their power systems.

“…This has obviously led to rural to urban migration on the global note owing to the absence of electricity in rural areas. This trend can be arrested by the provision of basic infrastructures in a sustainable manner to the rural dwellers 27 . This will improve the standard of living and reduce mass migration to the cities.…”

Summary The utilization of renewable energy resources (RERs) in the traditional power system has gained a global recognition owing to their technical, economic and environmental benefits. The techno‐economic analysis of a microgrid system that consists of diesel generator (DG), methanol generator (MG), photovoltaic (PV) and battery system (BS) is implemented in this study to evaluate the performance of the power system. The feasibility study of the power system is implemented by using HOMER application tool and meteorological data provided by the National Aeronautics and Space Administration. The analysis indicates that PV‐DG‐MG‐BS microgrid system is the most optimized configuration based on the net present cost (NPC) of $213 405.4, cost of energy (COE) of $0.256/kWh, renewable fraction of 88.6%, diesel fuel of 3055 L/y and DG operating hours of 1037 h/y. The results obtained from the optimized configuration translate to a substantial reduction in NPC, COE, diesel fuel and operating hours of DG when compared to the base case study. This indicates that the combination of DG, PV, MG and BS in a microgrid system is the most economical configuration to achieve a feasible result. Moreover, sensitivity analysis is carried out to investigate the impacts of solar radiation, load demand, fuel cost and inflation rate on the performance of the power system. The results obtained from the study clearly prove the effectiveness of using RERs to increase the sustainability and performance of the power system. This improves the standard of living and economic activities in areas where the microgrid systems are sited.

Hybrid power systems are technically suitable for providing continuous and quality power to remotely located dwellings and have the potential of reducing the greenhouse gases emissions. The present study aims at finding an optimal hybrid power system based on wind, solar, diesel, and battery backup, which can address the load requirements of a village (Muhavoor, India). The present study utilizes the HOMER software for sizing the major power components, performing economic analysis and estimating greenhouse gas emission. It uses the minimum cost of energy as the basis for optimum system selection. Local load, wind speed, and solar radiation data along with technical and financial input of wind turbines, solar photovoltaic panels, diesel generators, inverters, and fuel are considered in the simulation. Several options have been considered in the study including: diesel, PV/diesel/battery, wind/diesel, and PV/wind/diesel/battery hybrid power systems. Based on the simulation results and analysis, the PV/diesel/battery system with 53MW capacity of PV, 16.55MW diesel generator capacity, 3,520MWh of battery backup, and 15.5MW of converter is recommended as the best option for the concerned village. This system is capable of meeting the entire load of the village with annual energy yield of 92,549MWh with an excess energy of 7,262MWh. Of the total electricity produced, PV panels generate 92.71% with a renewable fraction of 89.2% at an energy cost of 0.117US$/kWh. The total cost of the proposed hybrid power system can be recovered in 11 or 8 years with positive cash flows at the end of year 12 or 9 based on sale of electricity alone or with additional income from fuel savings and greenhouse gases credit incentive.
