|20140103888||METHODS AND SYSTEMS OF NETWORK VOLTAGE REGULATING TRANSFORMERS - Methods and systems of network voltage regulating transformers are provided. A network voltage regulating transformer (NVRT) may provide voltage transformation, isolation, and regulation. A NVRT may further provide power factor corrections. Multiple NVRTs may operate autonomously and collectively thereby achieving an edge of network voltage control when installed to a power system. A NVRT comprises a transformer, a VAR source, and a control module. The input current (i.e., the current through the primary side of the transformer), the output current (i.e., the current through the secondary side of the transformer), and/or the output voltage (i.e., the voltage across the secondary side of the transformer) may be monitored.||04-17-2014|
|20140039711||DYNAMIC SOURCE BALANCING METHODS AND SYSTEMS - Dynamic source balancing methods and systems are provided. Power may be provided to a user from one or multiple energy sources. At any time point, the multiple energy sources may have different LMPs and power flow among the energy sources may be controlled such that a user's energy costs are reduced or minimized. Energy arbitrage may be realized for a user by taking into account of various factors related to the energy sources, the power grid, the power market, and/or the user.||02-06-2014|
|20130278235||SYSTEMS AND METHODS FOR DYNAMIC AC LINE VOLTAGE REGULATION WITH ENERGY SAVING TRACKING - Systems and methods for dynamic AC line voltage regulation are provided. A simple and cost-effective method for achieving AC line voltage regulation in AC systems including split-phase systems, of which the voltage for each voltage line may be regulated over a specified range, is provided. Buck and boost regulation is achieved for lowering or increasing the line voltage, respectively, with reference to the incoming grid voltage. Systems for dynamic AC line voltage regulation may comprise an AC/AC converter which uses fractionally rated switches and magnetics that handle only a fraction of the load current, resulting in lower costs. The use of an AC snubber further provides safe and robust switching of the main switching devices by eliminating failure prone switching sequences that are dependent on accurate assessment of voltage and/or current polarity for AC or bi-directional switches.||10-24-2013|
|20130173078||Systems and Methods for Harmonic Resonance Control - Systems and methods for harmonic resonance control are described. In some embodiments, a system comprises a first switch-controlled VAR source and a harmonic management block which may each be configured to be coupled to a distribution power network. The first switch-controlled VAR source may comprise a first processor, a voltage compensation component, and a switch. The first processor may be configured to enable the voltage compensation component after a delay by controlling the switch based on first proximate voltage after a duration associated with the delay to adjust voltage volt-ampere reactive. The harmonic management block may be configured to compare a second proximate voltage to at least one resonant threshold to detect potential resonance caused by enablement of the voltage compensation component and to engage based on the comparison the resonance compensation component to manage the potential resonance.||07-04-2013|
|20130138260||Systems and Methods for Switch-Controlled VAR Sources Coupled to a Power Grid - Systems and methods for switch-controlled VAR sources coupled to a power grid are described. In some embodiments, a system comprises a distribution power network coupled to a first switch-controlled VAR source. The first switch-controlled VAR source may comprise a processor, a voltage compensation component, and a switch. The first switch-controlled VAR source may be configured to obtain a first delay value, monitor a first proximate voltage, initiate a first delay duration based on the comparison of the first proximate voltage to at least one set point, the first delay duration being based on the first delay value, determine, with the processor, after the first delay duration, whether to connect the voltage compensation component based on the monitored voltage, and control, based on the determination, the switch to connect the voltage compensation component to adjust a network voltage or a network voltage component.||05-30-2013|
