Sizing of PV-array and battery storage for a stand alone hybrid wind-photovoltaic system

The PV-array and battery storage sizing of a stand alone hybrid wind-photovoltaic system is being addressed here. A probabilistic approach is used to arrive at the results. A new technique using a three event probability density instead of the traditional two event approximation is developed. This technique is then used to determine the optimum relationship between the number of PV panels and the number of storage batteries needed for the stand-alone hybrid wind-photovoltaic system, to meet a certain loss of power probability.; This method uses long term data of wind speed and irradiance taken for 30 years and the load specifications for a 'typical New England house' that is going to be powered by the hybrid system.
