Abstract:
Disclosed are an apparatus and method for automating a smart grid interoperability test and verification. It is possible to allow a tester to easily establish a test environment needed to test a CIM interoperability by providing a function that allows a tester to directly set and create a test node, a CIM test sequence, and a test sequence metadata, and it is also possible to reduce time and cost taken to test and verify the CIM interoperability by automatically compare and analyze a CIM message monitored in an actual test process with CIM message metadata set in a test scenario creation stage.
Abstract:
A method and system for use in controlling an electric network are provided. The system includes an Integrated Volt-VAr Control (IVVC) component configured to determine optimization parameters for slow dynamics electromechanical devices and fast dynamics DER devices coupled to the network. The slow dynamics devices are controlled by a present state of the electric network and a voltage rise table that is adaptively updated in real-time using a command output, or a power flow-based complete optimization routine that generates optimal setpoints for the traditional controllable assets and for at least some of the fast dynamics DER devices. The fast dynamics devices are controlled locally using a control algorithm that uses a reactive power contribution based on IVVC settings, based on photo-voltaic (PV) plant active power variations, based on power factor, or based on a voltage of the local electric network.
Abstract:
The method is for operating a remotely-controlled switching device of an energy management system. The switching device is mounted in series on a local electrically powered circuit on which are also mounted in series a load and an electronic thermostat. The method includes generating a first pulsed signal for controlling the switching device, the switching device opening and closing the circuit in response to the first signal. The circuit is opened to prevent the load from operating and is closed when operation of the load is allowed. The method includes generating a second pulsed signal for controlling the switching device at least when the circuit is opened by the switching device in response to the first signal. The second signal causes the switching device to temporarily close the opened circuit at given intervals for keeping an internal circuitry of the thermostat energized while still substantially preventing the load from operating.
Abstract:
Systems, methods, and apparatus embodiments for electric power grid and network registration and management of active grid elements. Grid elements are transformed into active grid elements following initial registration of each grid element with the system, preferably through network-based communication between the grid elements and a coordinator, either in coordination with or outside of an IP-based communications network router. A multiplicity of active grid elements function in the grid for supply capacity, supply and/or load curtailment as supply or capacity. Also preferably, messaging is managed through a network by a Coordinator using IP messaging for communication with the grid elements, with the energy management system (EMS), and with the utilities, market participants, and/or grid operators.
Abstract:
Systems and methods are provided for instantly and electronically reporting generation outages and/or availability to the grid operator. More specifically, the invention relates to systems for creating outage requests on a mobile device or web interface, accepting outage requests, processing the outage request, submitting the outage request to the grid operator electronically, receiving and communicating acknowledgement of receipt, acceptance or rejection of the outage request and starting the outage when an outage request is approved. In some embodiments, workflow design for processing the outage request may occur on a mobile device or web interface.

The apparatuses and methods herein facilitate generation of energy-related revenue for an energy customer of an electricity supplier, for a system that includes an energy storage asset. The apparatuses and methods herein can be used to generate operating schedules for a controller of the energy storage asset. When implemented, the generated operating schedules facilitates derivation of the energy-related revenue, over a time period T, associated with operation of the at least one energy storage asset according to the generated operating schedule. The energy-related revenue available to the energy customer over the time period T is based at least in part on a wholesale electricity market.
Abstract:
Phase balancing techniques for power transmission systems are disclosed. In one embodiment, a phase balancing protocol (240) includes executing a first phase balancing protocol (350) in relation to a first power transmission section (400a). A second phase balancing protocol (370) may be executed if the first phase balancing protocol (350) is unable to provide a phase balanced condition. The first phase balancing protocol (350) may utilize a first ordering sequence (364) to rank the current flow on the power lines (16) of the first power transmission section (400a), while the second phase balancing protocol (370) may utilize a second ordering sequence (384) to rank the current flow on the power lines (16) of the first power transmission section (400a). The order sequences (364, 384) are opposite of each other—one ranks the current flows from high-to-low, and the other ranks the current flow from low-to-high.
Abstract:
A logic ladder is utilized for conducting Advanced Measurement and Verification (M&V) of energy utilizing devices under curtailment control as part of organized energy management and/or demand response programs. The logic ladder starts with the most accurate method of conducting M&V and steps down from there: first step is measuring energy current directly at the device itself; the second step is use of an Appliance Codes datastore, which are listed capabilities of devices under load control to be used as a proxy if direct measurement of energy consumed at the device is not available; the third step is to poll the smart meter, if it is installed, and taking the energy differential before and immediately after curtailment; and the fourth step is to resort to analytics and historical model estimates of energy curtailment. Appliance Codes consist of a set of parameters that describe the energy utilizing device or appliance under load control, most notably the wattage used when in operation. By approximating the wattage when the device is in operation, one can accurately estimate the wattage under curtailment by simply knowing when the energy utilizing device was turned off and when it was allowed to come back on again after the energy curtailment event.
