Abstract

Abstract: With a large number of distributed photovoltaic devices connected to the grid, electric energy quality, short circuit capacity and power flow of distribution networks are all impacted more or less. Excess photovoltaic power that cannot be consumed locally will be transmitted back to the grid. So the traditional distribution networks are facing new challenges of reconstruction and upgrading. For distributed PV accessing into different functional areas, the issues are becoming more urgent about how to quantitatively analyze the constructions of distribution networks. In this paper, according to the new guideline of absorption capacity of distributed PV, load density and generation power density in typical functional zones are analyzed and comparison research is accomplished. Effects of distributed PV connected to grid on distribution network constructions in typical functional zones is investigated and suggestions of distribution constructions is proposed under different scenarios, which will provide guidance and advice for distribution network reconfiguration for the absorption of more distributed PV power.

Key words: typically functional areas, distributed photovoltaic power, distribution network construction and reforming, ability of PV absorption
