Energy storage technology is a critical aspect of future development of portable, scalable microgrid technology. One of the most important parameters in microgrid operation is the ability to predict the power and energy characteristics of any energy storage system. To achieve optimal use of renewable energy resources and energy storage, the energy storage system must be modeled accurately and must include all parasitic and operational losses from environmental controls. Furthermore, the energy storage operation must be modeled in conjunction with the particular renewable resource with which it will be used.

This seminar will discuss recent efforts to characterize the Vanadium Redox Battery (VRB) for microgrid applications. An electrical model of the VRB will be developed including charge and discharge efficiencies, balance of plant parasitics, and integration with photovoltaic systems. The model will be validated via a field demonstration at Fort Leonard Wood Army Base in Missouri. This model will be used as a basis for the development of a microgrid control strategy for heterogeneous energy storage systems, on and off-grid operation, and renewable energy.
