Technology learning from the lawmaker's point of view
The paper gives an overview over the German energy policy in the area of renewable energy sources. It focuses on the Renewable Energies Act (REA) of April 1, 2000, which has shown to be the main stimulus for the upswing of the market of renewable energies in Germany. One of the key features of the REA is the declining compensation schedule which aims at generating and stimulating learning curve ...

A modern MPPT control algorithm based on α–MPP pass–through detection and β–acceleration mechanism
A modern maximum power point tracking (MPPT) method based on the incremental conductance (IncCond) control algorithm is discussed. This method features a variable step iteration of duty ratio to get over the trade–off between dynamic performance and steady state oscillation around maximum power point (MPP). Moreover, in the aim to get an excellent precision and a swift response independently of ...
