Energy loss evaluation of a battery buffered smart load controller

The wider the dead-band is, the lower the energy loss because with a wide dead-band, for instance, 0.036 Hz, less charge-discharge energy is exchanged with the battery. Also, simulation results showed that lowering the droop constant increases energy loss as the regulation charge-discharge current is increased.
