Unlike technological systems, the dynamics of ecosystems are not "controllable". In order to ensure sustainability of TES system, the design and operation should be "viable" over long periods of time i.e. the design should be resilient. The term "resilience" has been defined across multiple disciplines with varying definition. Resilience can be used to describe a systemâs resistance capacity, coping capacity, adaptive preference or its transformative capacity to avoid irreversible changes while sustaining large shocks .
In this work, we employ the mathematical framework of viability theory  to analyze the viable operational domain of TES systems. We employ various dynamic resilience metrics to analyze and design control strategy for ensuring a sustainable operation of the novel TES systems. We compare the resilience of TES systems with that of conventional technocentric systems. This study helps us integrate the intermittent and uncontrollable dynamics of ecosystem with the control of technological systemâs paradigm and design "resilient" sustainable systems.
