Technical Solutions for Increasing PV Penetration in Distribution Grids in the Czech Republic in Terms of Interflex project

The paper describes proposed, implemented, tested and verified technical solutions supporting PV integration in the distribution grids. The solutions are implemented by ČEZ Distribuce, the largest DIstribution System Operator (DSO) in the Czech Republic, in terms of Horizon 2020 InterFlex project. New approaches for PV inverters control are introduced in a way that PV integration is less limited by voltage constraints or other grid issues. Different approaches for LV and MV grinds are explained. Smart solutions including autonomous functions of PV inverters, remote control or energy storage are presented to show the future potential for successful PV grid integration.
