Renewable energy sources, such as photovoltaic power systems and wind turbines,
have special power quality issues. For instance, photovoltaic inverters can interact
with existing network components leading to resonance phenomena. High harmonic levels
in renewable energy grids are also well-known. High emission of voltage/current
harmonics and inter-harmonics is one of the central power quality issues in renewable
energy applications. SATEC has gained more than twenty years of experience in power
quality solutions. On the basis of this experience, SATEC proposes the following
solutions for renewable energy customer applications:
