Dgdemonet: Impact of Volt/var Control on Increasing the Voltage Band Reserve – Results from Field Trial Validations
نویسندگان
چکیده
In the DG DemoNet Validation project a coordinated voltage controller was developed to actively integrate a high share of renewables into existing distribution systems. The impact of controlling the medium voltage transformer and the reactive power of distributed generation based on the actual voltages of critical nodes on voltage range and number of tap changer operations is analysed. Evaluation is based on records gained in two distribution systems where coordinated voltage control is operated for more than half a year.

متن کاملSmart 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...
