Embodiments of systems and methods for power demand management are described herein. More specifically, embodiments comprise systems and methods for powering, controlling, and/or operating various types of controllable load for integration with power fluctuations from intermittent power generation plants, such as photovoltaic arrays and wind turbine farms.

Based on information from a controller scheduling data traffic in a processing arrangement, a super capacitor unit is activated, whereby reactive power is fed to a system bus of said power system. The controller is configured to have information at time t(n) about the data traffic workload of the processing arrangement at time t(n+1). By triggering discharge of the super capacitor unit based on super capacitor data at time t(n+1), transients on a system bus voltage are, at least in part, smoothed out at time t(n+1), which reduces the need for reactive power of the power system, where said transients are related to the data traffic workload of the processing arrangement. The power efficiency of the power system can be improved by 3-4% by the reduction of the need for reactive power from a power grid, for which reason the electrical bill of an operator is reduced.

The controller is configured to determine, for each of the multiple demand charges, a peak demand target for the corresponding demand charge period by performing a first optimization of the risk attribute over the plurality of the scenarios, allocate an amount of the one or more energy resources to be consumed, produced, stored, or discharged by the building equipment by performing a second optimization subject to one or more constraints based on the peak demand target for each of the multiple demand charges.

A low speed controller can adjust one or more parameters of a cost function based on the relation between the projected state of the electrical system and the one or more parameters to effectuate a change to the electrical system to attempt to comply with the long-term objective.
