Today, due to the spread of solar panels and electric cars, we can less and less neglect their positive and negative effects on the low-voltage network. This is also important because at present, universal consumers are not required to mitigate the adverse effects of the network, which could lead to further problems in the near future.
One of the most significant detrimental effects is the voltage increase. I have examined in my paper through the two different reactive control solutions implemented by the inverters:
1. Fix cos (φ)
2. Q (U)
In order for the simulations to approach the behavior of a real network as closely as possible, a representative model for the Hungarian low voltage network was used. As a result of the runs, the operation of the reactive regulation was clearly demonstrated, in the case of the correct choice of parameters.
In the second part of my dissertation, I present the effects of the electric car chargers at home on the network, by comparing the charges at different times.
