Impact of renewable energy generation technologies on the power quality of the electrical power systems

The impact of the PQ problems found in the test network in case of large amounts of RE integration has been analysed. The analyses discussed in this study will demonstrate how the integration of RE generation systems can have a positive and at the same time a negative impact on the PQ of the system. It has been demonstrated how a clever integration can define the future behaviour of the system. Results obtained allowed to conclude that the impact of the RE generation technologies depends in a big part of penetration level, configuration of the system and the type of RE technology.
