Abstract: Superconducting magnetic energy storage (SMES) is one of the few direct electric energy storage systems. Its specific energy is limited by mechanical considerations to a moderate value (10 kJ/kg), but its specific power density can be high, with excellent energy transfer efficiency. This makes SMES promising for high-power and …

In general, co-energy functions are useful for multiport and/or nonlinear energy storage elements. Inverting constitutive equations may be avoided. In the linear case, energy and co-energy are numerically equal. the value of distinguishing between them may not be obvious. In the nonlinear case, the two are not equal.
