The number of electricity generation facilities with renewable energy sources (RES)
especially photovoltaic and wind energy connected to the grid and the share of installed
power in the electricity grids are increasing day by day. According to the data of the
International Energy Agency (IEA), while the installed power capacity of grid-scale
photovoltaic solar energy systems was 7.8 Giga Watts worldwide in 2010, this capacity has
reached 616.1 Giga Watts in 2022, increasing approximately 80 times, while the installed
power capacity of wind energy systems was 180.8 Giga Watts in 2010, this capacity reached
925.6 Giga Watts in 2022. Moreover, the installed power capacity of grid-scale photovoltaic
power systems is expected to reach 1335.5 Giga Watts and the installed power capacity of
wind power plants to 1532.1 Giga Watts by the end of 2027. As can be seen from the IEA
data, the share of renewable energy systems in the installed power capacity of the grid is
increasing and this increase is expected to continue.
In case of temporary failures in the grid, the rapid disconnection of many RES electricity
generation facilities from the grid can cause voltage fluctuations and imbalances in the grid.
In order to prevent large-scale electricity generation losses that may occur due to the
disconnection of the RES generation facility from the grid, and to support the generation
facility to the grid in case of temporary failures in the grid, RES electricity generation
facilities must have some features and requirements. These features and requirements vary by
country or region, but they usually include grid connection guidelines, technical standards for
equipment and facilities, and rules for the operation and management of the grid.
In this paper, the grid integration of RES generation facilities, the comparison of the grid
regulations of the countries, the features that should be in the RES electricity generation
facility, the errors that may occur in the RES electricity generation facilities, the reactions that
the RES electricity generation facilities and importance of energy storage should give in these
error situations, design of hybrid system the difficulties encountered, and a RES electricity
generation facility will be critically examined. The basic features that the facility should have
will be determined.
