Infeasibility Analysis of Half-Wavelength Transmission Systems
This paper analyzes the infeasibility of half-wavelength transmission systems in the aspects of power-frequency overvoltage and synchronization stability. The circuit model of the long-distance transmission system is established at first for steady-state

Introducing small storage capacity at residential PV installations to prevent overvoltages [PDF]
Low voltage distribution feeders are designed for unidirectional energy supply from transformer to consumer. However, the implementation of small-scale PV production units on local utilities may result in bidirectional energy flows.
