Technical, economical and environmental comparative analysis
Technical, economical and environmental comparative analysis of a Microgrid using battery and pumped hydro storage for remote area electrification in southern Algeria
The proposed stand-alone microgrid of the hybrid renewable energy system is sup- posed to be located in Aïn El Ibel, Djelfa in the north-central region of Algeria at 34.346° 8 latitude and 3.163° longitude. It is situated in a transitional zone between the dry high plains in the north and the desert in the south.
Figure 12a–d presents the Pareto front of the stand-alone microgrid system obtained for each algorithm based on LPSP and COE functions. On the Pareto front, the results show not only an optimal solution, but a group of optimal solutions (non-dominated solutions), a variety of design decision possibilities.
This outperforms MODA, MOGOA, and MOALO, where the offered optimal solutions show clear superiority compared to other presented results due to the design goal of the hybrid stand-alone microgrid system being to obtain a set of solutions to be adopted following different scenarios which can be faced in real cases.
The microgrid is analyzed for ten residential units in an off-grid community. The studied load profile is presented within the four seasons of the year—winter, spring, summer, and autumn—and has an average annual power consumption of 12.04545 kW. Figure 7. Load profile in the winter, spring, summer, and autumn seasons. Figure Figure 7. 7.
