20140183961 | Responding to Local Grid Events and Distributed Grid Events - A control system for an energy storage device is coupled to sensors on an electrical grid. The control system is configured to receive a measurement from each of the sensors. The control system determines, based on the received measurements, whether a grid event is a local event or a distributed event. The control system selects a response mode for controlling the energy storage device based on whether the grid event is determined to be a local event or a distributed event. | 07-03-2014 |
20140103726 | Controlling Power Conversion Systems - Methods and systems for controlling power conversion systems. In one aspect, a power management system includes a first power conversion system coupled to a first energy source and a second power conversion system coupled to a second energy source, and a control system. The control system causes, while the first power conversion system is operating in an active mode and the second power conversion system is operating in a standby mode, the second power conversion system to exit the standby mode, the second power conversion system providing a reactive power flow upon exiting the standby mode. The control system causes the first power conversion system to provide a compensatory reactive power flow to compensate for at least a portion of the reactive power flow from the second power conversion system. | 04-17-2014 |
20110273129 | Managing Renewable Power Generation - A power delivery rate from a renewable power source to a load is managed by determining, by processing circuitry, a change in a power generation rate, determining, by the processing circuitry, whether the change in the power generation rate exceeds a limit, and then, adjusting, by control circuitry, a power transfer rate to or from a power storage device, such that the adjusting is sufficient to prevent the power delivery rate from exceeding the limit. | 11-10-2011 |
20100201320 | DISCHARGING BATTERIES - Discharging a battery is accomplished by: applying an electrical stimulus to the battery; measuring a response to the electrical stimulus, the measured response providing an indication of discharge efficiency of the battery; determining a target frequency corresponding to a maximum discharge efficiency; and then discharging the battery with a discharge current profile comprising current pulses having a frequency component selected based on the determined target frequency. | 08-12-2010 |
