摘要：

The output of photovoltaic (PV) power is frequently fluctuated and difficult to be predicted. Besides, the estimation errors of load demands are significant due to the limited real-time measurement devices in distribution networks. Therefore, the conventional deterministic voltage control strategies cannot be well applied into active distribution networks. The over-limit voltage is the main reason for the PV curtailment or outage in distribution networks. This paper proposes a robust interval-voltage control strategy considering the uncertainties of PV output and load demand. The optimal var compensation strategies and the allowable active power interval for the PV station are calculated in the strategy. The method proposed guarantees system safety and is able to make the PV station running at the maximum power point tracking mode at most possible. Finally, by taking the modified IEEE 33-bus system as an example, the robustness of the proposed method is verified through Monte Carlo simulation. © 2016 Automation of Electric Power Systems Press.
