More Results

System level testing (not only the inverter is tested but also its impact on

the system).

The full hardware implementation would be challenging

2) CHIL/PHIL testing of centralized coordinated

voltage controller

• Optimal solution to voltage rise (due to high DG penetration) and voltage drop (during peak load periods) problems

• Benchmark LV network by CIGRE was used

State of Charge of the BESSBESS active and reactive power

• The SoC of the BESS was restored to the reference level of 40% during the night to early morning hours (12 a.m. to 9 a.m.), so that it is available for maximum charging during the midday hours of high irradiance. • The active power exchange of the BESS was restricted to periods of either high irradiance (charge) or high load demand (discharge), where the voltage rise/drop problems are greatest.







Thank you for your attention!
