20130193928 | CHARGE MANAGEMENT FOR ENERGY STORAGE TEMPERATURE CONTROL - Charging and discharging an energy storage device (ESD) generates heat and may prevent its temperature from dropping to unsafe levels. By monitoring and managing the charge and discharge of an ESD with respect to the periods of time in which demand charges are determined, the heating will have minimal adverse effect on demand charges. ESDs may also exchange energy in a controlled manner for heating purposes and reduce reliance on utility grid-based energy sources. ESD heating may also be made more efficient by offsetting the heating with load shedding during charging periods. Precharging the ESD while heating or preheating the ESD by charging and discharging can prevent new maximum demand levels from appearing and thereby limit increases in demand charges. | 08-01-2013 |
20130221929 | DELAYED REACTIVE ELECTRICAL CONSUMPTION MITIGATION - The electrical consumption mitigation provided by energy storage systems can be unreliable when a consumption peak lasts long enough to deplete the energy stored and the remainder of the peak is unmitigated. By implementing a waiting period between detecting the peak and discharging the energy storage in which characteristics of the peak are observed, a peak mitigation system can lengthen the effective discharge duration of the energy storage system and prevent unmitigated plateaus from appearing. For example, when a consumption plateau is detected, the system may discharge at a slower rate than when a spike is detected in order to prolong mitigation activities before the conclusion of the plateau. Thus otherwise-incurred demand-related utility charges can be reduced without having to increase the capacity of the mitigation system. In some cases, these processes are performed with respect to the bounds of demand-averaged time periods used to calculate demand charges. | 08-29-2013 |
