Voltage Stability: Course Photovoltaics #39

The connection of a PV system results in an increase of the grid voltage. But why is this, what is the problem and what can be done about it? The amount of voltage rise depends primarily on the active power fed into the grid, the active and reactive resistance of the grid, and the phase shift of the inverter. In order to reduce the voltage rise, inductive reactive power can be drawn from the grid by shifting the phase ofthe inverter. Various methods can be used: a fixed cosine Phi, the cosine Phi-P control and the Q-U control. Other possibilities to reduce the voltage rise is an expansion of the grid or the use of adjustable local network transformers. ---------------------------------------------------- This video is part of the PViTeach program, which offers many free courses on photovoltaics and even offers the opportunity to earn an official certificate.
