Quantitative analysis of distributed and centralized development modes for renewable energy

Abstract

Global renewable energy has maintained a steady growth in recent years under the support of national policies and energy demand. It is necessary to analyse the experience of renewable energy development mode in developed countries so as to provide reference and guidance for the renewable energy development in other countries. Firstly, the definitions of distributed generation in 18 typical countries or organizations are compared and summarized. On this basis, three basic characteristics of distributed generation are provided. Finally, Empirical analysis of Germany's renewable energy development mode is studied, which analyses the selection of development mode for wind and photovoltaic power. Moreover, the distributed photovoltaic generation accounts for more than 95%, and distributed wind power generation installations account for over 85% in Germany.
