Improving Dynamic Response and Transient Stability

For applications reliant on battery start-up as a primary energy source, this function can be expected to increase the number of engine ignitions approximately tenfold and would quickly decrease the life of a familiar lead-acid battery, disregarding the high power demands for quick acceleration. Furthermore, the rapid inversion of power expected to be recovered can be taxing and inefficient with a typical battery system. ESs can be used to

Power systems that are reliant on hybrid HESSs are inherently dependent on a good dynamic response to maintain operational stability. Functions implemented to minimize energy losses include intermittent shutdown when not in use, and this is where stability becomes critical for the rapid dynamics involved in these changes. Transient stability issues that arise from unexpected operating failures during start-up or at steady state can be predicted to an extent, and are important to consider during design. 

Each topology design as a unique method of integrating ESS devices requires a separate investigation to develop d5mamic stability models. The transient stability issues that are easily foreseen can also be addressed during this analysis.
