Extensive increases in electricity cost added to the numerous power outages encountered in developing countries has led to the deployment of hybrid energy supplies that mainly ensure continuity of power supply while attempting a reduction of electricity generation cost. This paper, specifically deals with the cost optimization of electricity generation from a grid connected hybrid solar and diesel generator. An electrical audit was first conducted on a selected building: the Electrical Block of Accra Technical University. The load estimate led to a total energy of 234 kWh for all electrical gadgets with the exception of the air-condition systems. The estimate was used to design the hybrid system with HOMER software that resulted in a total capacity of 115 kW and a levelized cost of electricity of 0.472 $/kWh taking into consideration no power outage in the year. Furthermore, the proposed hybrid system was made of a grid connected solar system that supplies the full load with the exception of the air-condition systems while the National Grid is used to cover the rest. In situation of power outages, the Generator Set takes over the National grid while the solar is still connected to the Grid. This mechanism was simulated and the cost of electricity in absence of the grid was estimated at 1.496 $/kWh. A general cost of electricity taking into consideration 90% ON period of the grid against 10% Off period of the grid per year, was estimated to 0.574 $/kWh. Besides, the proposed system produced savings in emission of carbon dioxide, 26.42 kg/year, sulfur dioxide, 115 kg/year and Nitrogen oxides, 56 kg/year. Finally, the system yielded a very good payback period of 10.43 years with regard to a lifetime of 25 years.

“…Load demand is also an important factor in determining the right combination of components. Most studies have focused on variable load or fixed load throughout the lifetime of the project [12][13][14][15][16]. Therefore, the reliability of the system is assumed to be the same throughout the lifetime of the project.…”

This paper presents the impact of load expansion to the hybrid photovoltaic (PV)-wind system design. System reliability and total project cost are the design objectives taken into consideration in determining the optimal size of the system. The size of the hybrid system components are restricted to specified constraints. An Iterative-Pareto technique is used to obtain the combinations of components. Results show that the increment of load demand reduces the reliability of the system. In addition to that, the total cost of the system when load is expanded is higher than the system with the initial load demand.
