摘要： A control system for a distributed power grid includes a simulation module operative to directly interface with operational control of distributed energy resources (DER) to develop and when necessary dynamically modify control inputs of the distributed power grid. By conducting a decentralized and distributed simulation of DER topology (components and their surrounding infrastructure) each distributed control module can simulate control response characteristics of a plurality of DER to determine a control methodology necessary to achieve a desired target. Once developed the same control inputs can be directly applied to physical DER and thereafter monitored to validate performance. Once validated, operational control of the DER is established while ongoing modifications of the control inputs continues in parallel to maintain desired performance.

摘要： Distributed grid intelligence can enable a virtual power grid. Multiple consumer nodes can have local power sources, and be coupled to a same point of common coupling (PCC). The consumer nodes can be controlled by distributed control nodes at the consumer nodes. The control nodes control the distribution of power from the local power sources based on local power demand of each respective consumer node, and also based on distribution of power from the other respective control node. Thus, consumer nodes can share power generated locally, but operate independently without the need for central management or a central power plant.

摘要： Data aggregation enables a local control response based on forecasted actions at a consumer node of a distributed grid network. A consumer node includes a local energy meter that receives grid condition information, including an aggregation of multiple inputs indicating an electrical condition of the grid network, local operating conditions at the PCC, and local power demand. The consumer node accesses rate information for the grid network indicating a consumer power price and a market power price. Based on the rate information and the aggregation information, the consumer node calculates an output power to generate with a local power converter, which outputs the power based in accordance with the calculation.

摘要： A method is provided for efficiently managing energy consumption using stored energy. The method accepts input energy (e.g., from a power utility) and maintains a record of energy consumption. An energy consumption peak is predicted in response to analyzing the record of energy consumption, and the input energy is augmented with stored energy during the predicted energy consumption peaks. More explicitly, a peak shaving value is selected based on a fraction of the predicted energy consumption peak, and the stored energy is used when energy consumption exceeds the peak shaving value. In one aspect, after a determination is made to use stored energy, it is simply used while it is available. Otherwise, it is supplied based upon an analysis of a predicted value of the stored energy.

摘要： Described herein are apparatuses, systems and methods for configuring and managing the combination of strings of photovoltaic energy generators to improve the energy production performance of such generators. The strings of photovoltaic energy generators are connected to terminals in a combiner box having receptacles for receiving removable modular units of various types. Removable modular units with measurement capabilities are used in the combiner boxes to measure the direct current input provided by the strings; and in light of the measurements, the removable modular units can be selectively downgraded to simpler units that do not have measurement capabilities to reduce cost, and/or selectively upgraded to more sophisticated units that can adjust the output of the respective strings, such as upconverting the output voltage of the respective strings, to improve the performance of the strings.
