Power decoupling of pulsating grid side power from constant source side power is one of the paramount issues in single phase-phase grid-connected renewable systems. The principal aim of such systems is the decrease of the capacitance of the decoupled capacitor. However, this causes some problems such as an increase in the total harmonic distortion (THD) of injected current to the grid and bus v...

The main solution to the problems of persistency and uniqueness in identification of digital objects in a web environment is provided by using digital identifiers instead of URL.
