Question

Do DER installations reduce distribution losses? If so, why?

Short answer

Therefore, DER installation reduces the distribution losses and the reason is explained.

Step-by-step solution

Distributed Energy Resources.

The Distributed Energy Resources are power generation resources and the tiny electrical device generally installed near the centre. Distributed Energy Resources can reduce distributed losses. Still, the location of the DERs is also a factor in reducing the losses and length in which energy is provided to the grid.

Working of Distributed Energy Resources.

The Distributed Energy resources supply the additional reactive power to the loads and distribution lines. Adding the reactive power reduces the angle between the voltage and current, reducing the current's lagging component and improving the voltage regulation.

By improving the voltage regulation, losses in power distribution are also reduced. Therefore, DERs can reduce the distribution losses by adding extra reactive power.
