Study on an optimum ratio of PV output energy to WG output energy in PV/WG hybrid system; Taiyoko/furyoku hybrid hatsuden system no saiteki yoryohi ni kansuru kento

Abstract

A photovoltaic power (PV) and wind generated power (WG) are an unlimited clean energy source, yet their output is unstable depending on the fluctuation of weather conditions such as solar radiation and wind velocity. Consequently, a large-scale power storage equipment is necessitated leading to a high cost especially in an independent system. As a solution, a method is available in which PV and WG are combined so that the effect may be utilized for stabilizing the output of a system as a whole, at a site where a fluctuation pattern is different between photovoltaic energy and wind energy. In building a hybrid system by PV and WG, sites with such supplementary effect existing were selected from the viewpoint of stabilizing the fluctuation of the power generation in the long run; and then, an examination was made on the optimum PV capacity ratio (%Ppo) in each site. As a result, it revealed that the %Ppo had great bearing on a ratio of PV energy fluctuation to WG, which was converted to a numerical formula. A comparatively simple examination by means of meteorological data also indicated that the share ratio was possibly optimized between the quantities of PV and WG energy. 4  More>>
