PROPOSAL OF A HYBRID METHODOLOGY FOR HOSTING CAPACITY ANALYSIS

Abstract

– The concept of hosting capacity (HC) is becoming more widespread, as it is a comprehensive approach that allows understanding the impacts of distributed energy resources into the distribution system. Several methods for calculating HC have been developed in recent years and are classified into deterministic, stochastic and time series, each with its respective pros and cons. Within this context, in this paper the authors present a hybrid methodology that combines deterministic and time series methods to find a real feeder hosting capacity, located in “Poços de Caldas” city, Brazil, from the utility company “DMED”. This feeder was modeled and analyzed taking into account variations in loads and power injection by DER’s on the system’s buses. Finally, the results achieved demonstrate the effectiveness of the proposed methodology
