Abstract: A computer-implemented method, according to one embodiment, includes: receiving an energy consumption profile which spans multiple intervals in a period of time, and predicting a net energy demand of a consumer system over the period of time.

Furthermore, an initial state of an energy storage device electrically coupled to the consumer system is computed according to the updated energy consumption profile. The initial state of the energy storage device is also based on a second multiple applied to each of the greatest amount of underprediction, and the greatest amount of overprediction.

Abstract: A system and method is presented for observing and efficiently enforcing control limits in powerflow studies of electrical power systems, using a novel optimality criterion. The method applies to any automatic control in which the controlling resource is limited by a maximum or minimum value, such as MVArs in generators, the tap ratio in load-changing transformers, or real power output in AGC-participating generators. In the absence of information about relative priorities among automatic controls, or about their dynamic behavior (as it is the common case in steady-state powerflow studies), the new optimality criterion provides the most reasonable method for deciding among multiple possible alternatives of saturated controls. The criterion is based on underlying physical principles that yield exact results in the idealized lossless transmission network, and hold also true to a great degree in real high-voltage transmission networks.
