Modeling of photovoltaic microgrids for bulk power grid studies

The integration of photovoltaic (PV) microgrids will have a transformative impact on the smart power grid. However, there are a number of research problems that must be studied to facilitate penetration of PV-generation systems into power grids. These problems are: i) PV models based on manufacturers' data that are non-confidential and can be used by smart grid stakeholders for microgrid studies; ii) PV-generating station models that are validated and non-confidential that can be used by utilities for bulk power flow and short circuit studies; and iii) PV-generator equivalent dynamic models for bulk power system stability studies. This paper seeks to address the modeling challenges of PV-generating stations.
