New PV system design strategy mitigates oversizing, curtailment by applying volt-watt droop control. Researchers suggest avoiding overvoltage-induced curtailment can reduce NPV and increase LCOE but improves SCR & SSR rates. The study evaluates four scenarios with varying PV installation numbers and locations for grid-connected residential photovoltaic systems, considering the economic trade-offs of voltage thresholds.
- Implementation of volt-watt droop control in new PV designs
- Research findings show potential reduction in net present value (NPV) and increase in levelized cost of electricity (LCOE), while improving short-circuit ratio (SCR) and solar fraction (SSR)
- Comparison across four scenarios, differing in PV count and placement for residential systems
- Critical evaluation of economic implications due to varying voltage thresholds
- Published study details: Techno-economic assessment considering overvoltage-induced generation curtailment
