Grid Integration

Most of the administrative burdens complicating the large scale integration of photovoltaic (PV) systems on electricity distribution infrastructures, regard difficulties during the Grid Integration. More specifically they include:

PV systems, in order to be allowed to connect to the electricity distribution or transmission grid, must follow certain rules and meet certain technical criteria, usually defined by grid operators and electricity market regulators. Often these provisions, which must be satisfied by a PV project either at the time of requesting access to the grid or during the test and commissioning phase, do not take into account the characteristics of PV systems and may consequently represent a barrier to their market penetration.

Connection to the grid is often the last and decisive step in the development of a PV system, but it remains important early in the process of developing a PV system, because one of the first tasks a PV developer must undertake is to verify if a grid connection is available in the premises where he has chosen to develop a PV system. While there is a general flow for the grid connection process, in practice many variations appear in some European countries, thus complicating the grid connection procedures.

  • Barriers related to grid capacity issues

The consistent growth of PV and other RES installations in several European countries in recent years clearly represents a technical and regulatory challenge to the European transmission and distribution grid infrastructure. Unfortunately, in some cases this challenge is not tackled properly and therefore significantly limits or totally blocks the installation of further capacity.

PV GRID will try to identify, analyze and tackle these barriers in order to facilitate the grid integration procedure for PV systems across Europe.
