Özet

Renewable based distributed generation (DG) particularly in low voltage (LV) distribution networks may cause voltage limit violations, line overloads and increase in network losses. Siting and sizing of DG penetrations are generally done according to the worst case scenarios. However, since these cases occur rarely in long term operation, a realistic design enables more DG penetration. There are numerous conventional methods, each having several benefits and drawbacks. Local energy management systems can also be part of the solution. This study investigates the negative steady state operational impacts of DG on LV distribution networks and proposes a microgrid management approach to mitigate those impacts. A field data-based virtual test bed is used to simulate undervoltage and overvoltage issues and a microgrid energy management approach is developed and tested to minimize the negative impacts on the network. Moreover, Digital Audio Broadcasting (DAB) as data transmission means in microgrids, is discussed as an adaptable communication solution for its real-world implementation.
