| Abstract | Remote areas do not have connection to electricity network. Moreover, using conventional resources are not feasible, as they cause a lot of greenhouse gases (GHG) which increase the effect of global warming. Such areas have multi renewable energy resources. Using single renewable resource, large battery storage system will be required due to their fitful and unpredictable nature. The integration of hybrid renewable energy system with batteries reduces the system variations and economics, in addition to no emissions will be caused by the system. This paper presents a techno economic analysis for six scenarios of a stand-alone hybrid energy system to supply the electrical energy needs for a remote area in Egypt (shalateen city). Optimal solution was obtained using HOMER software which can supply the demand load for the studied city of 68458.13kWh/day with a peak 6900kW based on the net present cost (NPC) and cost of energy (COE). The proposed hybrid renewable system for the demand load was pv/wind/hydrokinetic/battery, while the other scenarios for the system are pv/battery, wind/battery, pv/wind/battery, pv/hydrokinetic/battery, wind/hydrokinetic/battery. From results the optimal solution was the proposed system with 17438 kW PV array, 547 wind turbine with 6.25kW rated power, 9 hydrokinetic turbine with 5kW rated power, 1118 battery with 100kWh rated energy, and 9661 kW converter. The net present cost (NPC) and the cost of energy for the optimal solution were 97.9M$ and 0.307$/kWh respectively. Pv/wind/battery system also gives NPC and COE like the optimal solution, where its NPC is 98M$ and COE is 0.307$/kWh. For single resource systems, pv/battery, and wind/battery, the NPC are 104.6M$ and 130M$ respectively. The cost of single resource system represents a large cost compared to cost of hybrid system. Moreover, the cost of pv system is less than wind system which mean that the solar irradiance is more compared with wind speed in studied location. For two sources hybrid systems, pv/wind/battery, pv/hydrokinetic/battery, and wind/hydrokinetic/battery, the NPC for them are 98M$, 103.5M$ and 129.2M$ respectively. The results show that hybrid system is more economic for remote areas in Egypt compared to single source system. Hybrid renewable energy system is a feasible solution for remote areas in Egypt due to their locations from the electricity grid. In addition to the above it solves the problem of greenhouse gases which are produced from conventional resources which are usually used in these locations. |
