Conclusions
• PV penetration most limited when minimum load on network
• Review MV/LV transformer tap changer positions for increasedPV penetration
• Load shifting by customers observed, enabling larger PVpenetrations
• PV must be considered in the future network planning
• Economic aspects:
– the "added value" of PV (economic + others) exceeds theperceived inconveniences to the utilities
