This means that PV participation in voltage regulation is more effective in a lower voltage grid than a medium voltage one. On the contrary, if PVs do not participate in reactive power support, the hosting capacity of medium voltage grid to PV would be higher than the low voltage one.
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 paper discusses the modelling requirements for PV system integration studies, as well as the possible techniques for voltage rise mitigation at low voltage (LV) grids for increasing PV penetration. Potential solutions are listed and preliminary results are presented. Solar energy is the most important natural energy source to the world.
Voltage control is one of the urgent issues in distribution systems for solar PV integration. Many LV networks have been designed decades ago, and are not well prepared to accommodate the large amount of power flowing through the grid. This paper describes the mechanism of the voltage rise issue, and the possible mitigation solutions.
The power quality of a PV system integrated with the distribution system in the tropical area was analyzed by recording the voltage unbalance, flicker current, and voltage harmonics at the PCC between the PV station and the Colombian grid (Granja et al., 2018).
