Integrated control of battery energy storage management system considering PV capacity firming and energy time shift applications

Abstract

This paper present a complete battery energy storage management scheme to maximize potential value that can be brought forth to medium voltage feeders. In general, the potential performance benefits produced by possible energy storage applications include improved system reliability, dynamic stability, enhanced power quality, transmission capacity enhancement and area protection. Here we propose a unique control algorithm that enhances coordination of Renewables Capacity Firming and Energy Time Shift (ETS) applications. Optimization of control parameters and set points are considered for management between the mentioned applications with the help of the proposed architecture. The design is tested on an EMTP® simulation platform and the results indicates that the proposed architecture provides capability to include multiple functionality of the energy storage device maximizing the value of the energy storage in power grid.
