VOLTAGE DROP CALCULATIONS & DESIGN OF URBAN DISTRIBUTION FEEDERS

Smart Inverter Voltage Control on Distribution Feeders

Smart inverters are studied in both the dynamic/transient and steady state in a simulation environment. Using EPRI OpenDSS, five real California feeders are simulated over a 95 day period while the PV penetration and smart inverter fraction are varied. From the simulations, it is shown that smart inverters operating under different Volt/VAr based control schemes improve feeder conditions. The i...

Optimized Fuzzy Controller Design in Unbalanced Voltage Drop Mode for Dynamic Voltage Restorer

The loss of balanced voltages involves a voltage drop due to symmetric three-phase errors, or the initiation of high-power three-phase loads or symmetric three-phase switches. While these events in an unbalanced way lead to asymmetric voltage drops. Voltage drops can cause asymmetric load on the power grid, the occurrence of volatility, and even network power outage. One of the most common ways...
