The use of the solar power plant can be interconnected with distribution networks in electric power systems, both medium-voltage networks and low voltage networks. In this study, a 3 MWp capacity of solar power plant was conducted with the medium-voltage network system of X City.
Some major standards for PV integration in distribution systems such as IEC 61727, IEEE 1547, and VDE-AR-N4105 are defined and used in to ensure that the power quality and stability defined by grid codes for PV sources connected to the grid are maintained.
The existence of a 3 MWp solar power plant that is connected to the X City electrical system can help improve the system voltage on each bus with a value that is still in accordance with the standards in SPLN 1: 1978, which is minimum -10% and maximum + 5% of nominal voltage .
