Probabilistic Hosting Capacity Evaluation of Distribution Network Considering Impacts of Demand Response and Energy Storage System

The rapidly increasing penetration of distributed generation (DG) such as photovoltaic (PV) has brought various impacts such as voltage rise on distribution network (DN). In this context, it is necessary for a distribution network operator to evaluate the hosting capacity when planning network development. Meanwhile, demand response (DR) and energy storage systems (ESS) have proven to have the ability to provide various grid support services. This paper proposes a multi-scenario-based model to evaluate the probabilistic hosting capacity of a distribution network under different given tolerated curtailment ratios. In the proposed model, the demand response and energy storage system optimal operation strategies are also considered, and the scenarios are generated according to the uncertainties associated with solar irradiance and load demand. The effectiveness of the proposed method is demonstrated by a case study with a modified IEEE 33-bus distribution system.
