The traditional distribution grid is operated radially and has passive consumers that only draw power from the grid but feed nothing back This operation is already under change so the traditional voltage regulation methods currently used in distribution systems need major modifications if we are to uphold the proper quality of electricity supply. In our paper we present the possible impact photovoltaic generation will likely have on the medium voltage grid and the means to lessen these impacts: we investigate various control options for solar inverters and a line voltage regulator as well. Simulation results indicate that the voltage profile can be maintained within the allowed limits with these regulation methods.
