This tendency together with the falling price of the synchronous-type generator has potential to give DG a better chance at participating in the voltage regulation process together with other devices already available in the system. The voltage control issue turns out to be a very challenging problem for the distribution engineers since existing control coordination schemes would need to be reconsider ...

The DGs considered in this paper are supposed to be Photovoltaic (PV) generators, due to the growing demand of renewable energies. However, high penetration of DGs may cause considerable voltage fluctuations and deviations from the statutory limits. Thus, based on predicted values of load demand and PV generation, a set of voltage references of tap transformers and DGs is optimized, using Genetic Algorithms (GA) optimization me ...
