“…However, DR programs have not been concerned in the proposed multi-criteria decision-making technique. In [71], the researchers used HOMER Pro for the techno-economic planning of islands in South Korea. In this study, three scenarios based on the three off-grid islands located in South Korea are optimized.…”

The optimal planning of grid-connected microgrids (MGs) has been extensively studied in recent years. While most of the previous studies have used fixed or time-of-use (TOU) prices for the optimal sizing of MGs, this work introduces real-time pricing (RTP) for implementing a demand response (DR) program according to the national grid prices of Iran. In addition to the long-term planning of MG, the day-ahead operation of MG is also analyzed to get a better understanding of the DR program for daily electricity dispatch. For this purpose, four different days corresponding to the four seasons are selected for further analysis. In addition, various impacts of the proposed DR program on the MG planning results, including sizing and best configuration, net present cost (NPC) and cost of energy (COE), and emission generation by the utility grid, are investigated. The optimization results show that the implementation of the DR program has a positive impact on the technical, economic, and environmental aspects of MG. The NPC and COE are reduced by about USD 3700 and USD 0.0025/kWh, respectively. The component size is also reduced, resulting in a reduction in the initial cost. Carbon emissions are also reduced by 185 kg/year.

“…The system's performance ratio measures the relationship between energy output and radiation incidence in a specific area, as displayed in Figure 11. It is acceptable for a system this size because it hovers around 0.4 for most months in a year [10][11][12][13][14][15]. Following several software loss corrections, as shown in Figure 12, the output energy to the load is obtained.…”

The energy challenge has become the most critical issue in this century, leading to many global conflicts. Solar power is broadly acknowledged as a green technology. A stable and non-outages grid with the lowest cost becomes the target for many people interested in energy, especially after a sharp rise in the regular price of energy. This academic research aims to design a low-cost system for a Canadian home to significantly reduce the power bill of a home in St. Johns, Canada. A house or a small industrial facility can generate enough energy to meet its needs by combining two or three energy sources. In St. John's, Newfoundland, the average yearly wind speed is 6.7 m/s, and monthly average solar radiation exceeds 220 W/m2 . A typical R2000-compliant home uses 68.4kWh per day on average. Many distant dwellings can benefit from hybrid energy systems to generate energy. Photovoltaic and wind power generates electricity by combining solar cells with wind turbines, then integrated into a battery bank. The energy is transferred to an inverter, which produces an alternating current. Before using such energy, significant concerns, such as the input-output relationship, must be considered. A charge controller is required to monitor variations in the energy sources, and a power inverter is needed to convert electric current to alternating current. The economic and geological feasibility is conducted for this case study
