Impact of distributed generation facilities on an urban network

Many of modern distributed generation plants are based on photovoltaic cells using power electronic units for energy transmission into the electrical network. This increases the emission of high-frequency currents into the network and affects the operation of power line communication devices and energy meters. A real LV network in Germany was investigated by the authors with the purpose to estimate the actual situation in the network with respect to high-frequency distortion and to characterize the possible impact of the presented distributed generation facilities on the network operation.
