Methods for Evaluating DC Arc Incident Energy for Battery Energy Storage Systems 

Renewable energy systems continue to be one of the fastest growing segments of the energy industry. This paper focuses on the understanding of how energy storage technology behaves under direct current (dc) arc conditions. Because of the fast proliferation of renewable energy systems and the lack of formal dc equivalent calculation guidelines such as IEEE 1584 for alternating current (ac) systems, it has been necessary to rely on different equations and models presented by various researchers when calculating arc-flash (AF) incident energy (IE) for dc systems. This paper discusses the behavior of energy storage systems under arcing conditions and presents the results of available methods to estimate the dc arc-flash incident energy. This paper provides a comparative analysis of a proposed arc-flash incident energy calculation method against available laboratory tests. Explanations are provided regarding the effect the various types of batteries may have under short-circuit (SC) and arcing conditions. Comparisons of the proposed calculation method simulation results and laboratory dc arc test measurements are included.

Application of DC AF Incident Energy Reference Boundary Area Plots in Plots in TCCs Considering Input Parameter Variability

This work introduces the concept of dc C-areas in time-current characteristic plots (TCCs) for establishing a reference of dc arc-flash (dc AF) incident energy (IE) during the protection and coordination study.  C-area plots represent a constant allowable incident energy for a piece of equipment while considering arc flash input data variability.  The dc C-area reference plots allow protection engineers to select overcurrent protective device settings in TCCs while keeping track of the allowable incident energy. This work explains the theory and derivation of the dc C-areas, the impact of the input parameter variability, and provides a detailed explanation of the data collection challenges for performing a dc arc-flash incident energy analysis. This paper also includes application examples of C-areas for battery energy storage systems (BESS) and photovoltaic (PV) systems equipment protection and coordination studies.
