Modeling of power distribution systems with solar generation: A case study

The recent growth of renewable energy sources, i.e. wind and solar sources, in electrical power systems is tremendous. Generation from renewable energy sources is mainly added to the power network in a decentralized fashion, and the availability of the generation depends on weather conditions. One of the most common renewable generation techniques is photovoltaic (solar) generation. Regarding the challenges of integrating renewables in power grid, there has been an increasing interest to study and analyze the behavior and performance of power systems with renewable generations. The proposed methods and algorithms require to be tested by means of simulating appropriate case studies. The purpose of this document is to present a case study of distribution power systems composed of a single-phase distribution bus, solar (PV) inverters and daily load profiles based on real and actual data. The distribution system is modeled as a modified IEEE 37 bus for which the modified data for single-phase analysis are provided. Moreover, a simplified model for PV inverter is used to obtain desired active and reactive output power given the weather condition, e.g. temperature and solar radiation. The modeling and data are based on [6].
