Abstract
- Diversifying the role of grid side converters (GSC) associated with distributed generation (DG) may have a technical and economic impact. The increasing number of residential photovoltaic systems can be exploited by distribution network (DN) operators in order to support and improve the power quality of the grid without considerable further capital investment. The GSC can support the grid during abnormal conditions but may also be used to improve the DN power quality by balancing out asymmetries and alleviating the grid from undesired harmonics. The proposed advanced control technique demonstrates through simulation and experimental results that the role of GSC can be upgraded to improve the power quality of the grid. Furthermore, the proposed control scheme is validated on a realistic low-voltage DN using data from the Cyprus Electricity Authority. Consequently, conventional practices by distribution network operators for improving the power quality can be re-assessed as the necessary power electronics hardware for mitigating grid problems are already present within the GSCs of DG systems.&nbsp
