    Abstract: A method, system and apparatus are provided for optimized load shaping for optimizing production and consumption of energy. Information signals indicative of a first load shape signal are obtained corresponding to a total load, a renewable energy load of one or more renewable energy sources and a non-renewable energy load of one or more non-renewable energy sources. The first load shape signal corresponding to renewable energy load is removed from a non-renewable energy load to obtain a resulting load shape signal. The resulting load shape is flattened signal by apportioning the resulting load shape signal across time intervals to obtain a flattened load shape signal. At least a portion of the first component corresponding to the renewable energy load is added to the flattened load shape signal to create an optimized load shape signal.

A control information is determined in the event that the regulation information is indicative of over- or underproduction. The control information is indicative of a control of the amount of electrical energy generated by power generating plants. The control information is determined based on the obtained regulation and generation information. Based on the time at which the regulation information is obtained, the remaining time of a predetermined interval is determined. Operating points for the plants are determined such that, for the remaining time, the amount of energy generated by the plants for the predetermined interval saves or generates at least one determined difference between the amount of energy generated according to the forecast and generation information. The operating points are based on the control information. The determined control information is output.

  • Patent number: 11581733
    Abstract: The present disclosure provides techniques for estimating network states using asynchronous measurements by leveraging network inertia. For example, a device configured in accordance with the techniques of the present disclosure may receive electrical parameter values corresponding to at least one first location within a power network and determine, based on the electrical parameter values and a previous estimated state of the power network, an estimated value of unknown electrical parameters that correspond to a second location within the power network. The device may further cause at least one device within the power network to modify operation based on the estimated value of the unknown electrical parameters. The leveraging of network inertia may obviate the need for probabilistic models or pseudo-measurements.
