Power is defined as the amount of energy consumed per unit time. This quantity is useful if the energy of the signal goes to infinity or the signal is "not-squarely-summable". For "non-squarely-summable" signals, the power calculated by taking the snapshot of the signal over a specific interval of time as follows.
One way of ensuring continuous and sufficient access to electricity is to store energy when it is in surplus and feed it into the grid when there is an extra need for electricity. EES systems maximize energy generation from intermittent renewable energy sources. maintain power quality, frequency and voltage in times of high demand for electricity.
New energy storage devices such as batteries and supercapacitors are widely used in various fields because of their irreplaceable excellent characteristics. Because there are relatively few monitoring parameters and limited understanding of their operation, they present problems in accurately predicting their state and controlling

Electrical equipment tends to be much more susceptible to damage than process equipment and structures. Scheffey et al. (1990) indicate that operating electronic equipment can be expected to fail at temperatures as low as 50 °C. They predict permanent damage to nonoperating equipment at 150 °C and failure of PVC cable at 250 °C.
