Abstract: Embodiments may include a method of curtailing an output level of an EG system. The method may include receiving, at a processor, a first dynamic control signal. The first dynamic control signal may include an instruction to adjust an output level of an EG system to a first output level. The method may also include maintaining the output level of the EG system at the first output level for a predetermined period. The method may further include determining, by the processor, whether a second dynamic control signal is received during the predetermined period. If a second dynamic control signal is not received during the predetermined period, the method may include ramping down the output level at a predetermined rate after the predetermined period until a predetermined failsafe output level is achieved. The predetermined failsafe output level may be maintained until a third dynamic control signal is received by the processor.

Abstract: Methods for controlling an energy storage device to reduce peak power demand at a site are provided. In one embodiment, load data corresponding to a load in a utility grid-connecting energy generation (EG) system is received. The load data may be sampled at a first predetermined interval, and the EG system may include an energy storage device. A load threshold level is received, and a discharge control signal is generated. The discharge control signal may be generated when the measured load is at or above the load threshold level. The control signal may be applied to the measured load for a second predetermined interval that is longer than the first predetermined interval.
