In this paper, the size optimization of standalone Photovoltaic (PV)/Wind turbine hybrids system for water pumping in Sirte City, Libya are compared using HOMER Pro, HOMER Beta, and iHOGA softwares, specifically the cost of energy (COE), total net present cost (NPC), and size of the system. Various loads of water pumping for farm land are used. The optimal system suggested by iHOGA had the lowest...
The Danish power system is characterized by a large penetration of wind power. As the nature of the wind power is unpredictable, more balancing power is desired for a stable and reliable operation of the power system. The present balancing power in Denmark is provided mostly by the large central power plants followed by a number of decentralized combined heat and power units and connections from abroad...
The work presents a reliability analysis of a stand-alone photovoltaic system for the supply of electric loads located in remote areas not easily reachable by the low voltage distribution network. The analysis is performed by characterizing the electric load behavior by means of a Montecarlo approach for taking into account the stochastic variability of the electrical energy demand. A Montecarlo approach...
