Distribution Voltage Regulation Through Active Power Curtailment With PV Inverters and Solar Generation Forecasts

Distribution Voltage Regulation Through Active Power Curtailment With PV Inverters and Solar Generation Forecasts Distribution Voltage Regulation Through Active Power Curtailment With PV Inverters and Solar Generation Forecasts Abstract: Distribution voltage profiles are subjected to overvoltage limit violations from high penetration of grid-connected photovoltaic (PV) systems. Such voltage rises seen at the point of PV interconnection can be mitigated by adaptively changing the active and/or reactive power injection from the PV inverter. This work proposes a local voltage regulation technique that utilizes very…

Stochastic Assessment of Voltage Unbalance Due to Single-Phase-Connected Solar Power

Stochastic Assessment of Voltage Unbalance Due to Single-Phase-Connected Solar Power Stochastic Assessment of Voltage Unbalance Due to Single-Phase-Connected Solar Power. Abstract: A stochastic method is presented in this paper to estimate the future voltage unbalance in a low-voltage distribution network with high-penetration of single-phase photovoltaic inverters (PVIs). The location and phase allocation of the PVIs are considered as input parameters for the stochastic simulation. The method has been applied to three different low-voltage networks: two in Sweden and one in Germany. In the…
