What is Grid Integration of Distributed PV Systems?
Grid Integration of Distributed PV Systems involves connecting rooftop and small-scale photovoltaic installations to the electricity grid while maintaining voltage regulation, power quality, and anti-islanding protection amid high PV penetration.
This subtopic examines inverter control strategies and energy storage coordination to ensure grid stability in networks with significant distributed PV. Key challenges include overgeneration during peak solar hours and voltage fluctuations. Over 20 papers in the provided list address related renewable integration issues, with Denholm et al. (2015) cited 544 times for analyzing California's solar duck curve.
Why It Matters
Grid integration enables high PV penetration without reliability loss, as shown in Denholm et al. (2015) duck chart analysis revealing mid-day net load drops requiring flexible generation. Erdiwansyah et al. (2021) highlight integration barriers for solar with conventional grids, emphasizing inverter controls for stability. In California, overgeneration from distributed PV necessitates storage and demand response, impacting 30%+ renewable targets (Denholm et al., 2015). This supports decarbonization goals by maximizing sustainable PV deployment.
Key Research Challenges
Overgeneration Management
High midday PV output causes net load drops, as in California's duck chart (Denholm et al., 2015, 544 citations). Conventional power must ramp rapidly, stressing grid operations. Mitigation requires forecasting and storage coordination.
Voltage Regulation Issues
Distributed PV inverters cause voltage rises in low-voltage networks under high penetration (Erdiwansyah et al., 2021). Reactive power control strategies are essential. Papers note coordination with energy storage for stability.
Anti-Islanding Protection
PV systems must disconnect during grid faults to prevent islanding hazards (Erdiwansyah et al., 2021, 429 citations). Detection methods face challenges with high penetration. Inverter standards evolve to address false tripping.
