Techno-economic analysis of off-grid renewable energy power station: A case study

This paper gives the techno-economic analysis of a wind-PV-diesel system with storage battery backup for an off-grid power station specially located in Dongwangsha, studying data from a particular site in littoral China. The simulation and optimization results indicated the most optimized sizing of hybrid system. Moreover, the sensitivity analysis is discussed at a diesel price of 2$/L and annual average wind speed of 4.41 m/s and interest rate of 6%. The proposed hybrid system is more cost effective and environmental friendly than the diesel only system.
