Combined with the operation characteristics of photovoltaic power generation system, mathematical model and simulation are established, control strategy bipolar inverter wide output maximum point tracking (MPPT) method conductance increment designed. The stable distributed system realized. results show that established in this paper can effectively reflect MPPT control. With change lighting con...

Despite the clean and renewable advantages of solar energy, instability photovoltaic power generation limits its wide applicability. In order to ensure stable power-grid operations safe dispatching grid, it is necessary develop a model that can accurately predict generation. As widely used prediction method, stacking has been applied in many fields. However, few studies have models research, we...

multiwall carbon nanotubes (mwcnts) are grown via chemical vapour deposition method directly on a stainless steel substrate. raman spectroscopy and transmission electron microscopy are the techniques chosen to characterize the structure of the synthesized carbon nanotubes: few structural defects are detected. after their removal from the stainless steel substrate, the as-grown mwcnts are then a...
