ABSTRACT In the context of high‐penetration of photovoltaic (PV) installation, the inherent fluctuation of PV generation leads voltage violations to the distribution system. The traditional voltage adjustment, such as capacitor banks and on‐load tap changer, is dominated by the distribution system operator. With the emergence of microgrid, multiple flexible resources, such as electric vehicle battery swapping stations (EV‐BSSs), can participate in distribution network voltage optimisation by dynamically changing the load time and amplitude characteristics. However, the uncertainty of resources, that is, the volatility of PV power and the randomness of loads, makes it difficult to precisely regulate the voltage. If the charge/discharge pattern of EV‐BSS can compensate for the fluctuations, the voltage regulation would be strongly supported. This paper proposes a collaborative operation framework between distribution networks and microgrid to coordinate voltage regulation in the distribution network, integrating conventional voltage control methods with the EV‐BSS. A PV inverter control strategy is also developed, incorporating both user satisfaction and the factors influencing PV generations. To further enhance system performance, a multiobjective optimisation model complemented by a confidence‐adjustable mechanism is developed to dynamically fine‐tune scheduling robustness under uncertainty. The effectiveness of the model is validated through case studies.
