Abstract
This study evaluates the performance of the Voltage Based Droop (VBD) control in mitigating overvoltage due to photovoltaic units (PV) in Low Voltage (LV) networks. The benefit of this primary control of PV inverters, with respect to the on-off oscillations, the voltage level and the captured energy in LV networks, has been already demonstrated with deterministic “worst case” approaches on small networks and for restricted time periods. These approaches do not consider the intermediate network operation states but only the extreme ones (lowest expected consumption - highest PV generation) and they often lead to over dimensioned and costly technical solutions. In this paper, the P/V control (implemented in the VBD control) is evaluated with a probabilistic analysis framework that considers the time fluctuation of the PV generation and of the voltage at the MV/LV transformer as well as the randomness of the consumption loads. The nodal statistical profiles of these fluctuating parameters are based on 15-min smart meters’ (SM) data recorded by the DSO. An existing LV network in Belgium is simulated in order to evaluate with a probabilistic approach the benefit of the proposed control.
