New load and infeed approaches for cost-efficient low-voltage grid design

The paper covers the derivation and application of new load approaches of private households for low-voltage power calculations especially in rural areas. In these areas private households have an over-average amount on consumption and a relatively high penetration of dispersed generation. That is why private households have a high relevance for an innovative and smart low voltage grid design. Therefore especially this group of consumer drives the transformation process of distribution grids founded on the rising development of dispersed generation, especially photovoltaics, and additional load patterns such as heat pumps and electric cars.
