The rapidly increasing penetration of distributed generation (DG) such as photovoltaic (PV) has brought various impacts on distribution network (DN), such as voltage rise and power decline. Considering that, the hosting capacity evaluation of PV in DN is essential to provide useful references for PV development. Meanwhile, the mobile energy storage system (MESS) has proven to have the potential of improving the HC for its ability to provide various grid support services. This paper proposes a multi-scenario-based model to evaluate the hosting capacity of distribuited considering the impacts of MESS. In the proposed model, the transit features of MESS are considered. Besides, the scenarios are generated according to the uncertainties associated with solar irradiance and load demand. The effectiveness of the proposed method is demonstrated using a modified IEEE 33-bus distribution system.
