  • Publication number: 20230384743
    Abstract: Systems and methods may use a low speed controller in addition to an economic optimizer to achieve long-term objectives without significantly disrupting or destabilizing an electrical system. Specific long-term objectives include maximizing a capacity factor incentive and regulating battery degradation, but the methods and systems herein can be extended to more long-term objectives. A low speed controller can adjust one or more parameters of a cost function based on the relation between the projected state of the electrical system and the one or more parameters to effectuate a change to the electrical system to attempt to comply with the long-term objective.

  • Patent number: 11539238
    Abstract: The present disclosure is directed to systems and methods for economically optimal control of an electrical system. A two-stage controller includes an optimizer and a high speed controller to effectuate a change to one or more components of the electrical system. The high speed controller receives a set of control parameters for an upcoming extended time period. The control parameters include a plurality of bounds for an adjusted net power of the electrical system. The high speed controller sets an energy storage system command control variable (ESS command) based on a state of adjusted net power of the electrical system and the set of control parameters.

  • Publication number: 20200005201
    Abstract: Electrical system controllers, computer-readable storage media, and related methods for stochastic control of electrical systems. An electrical system controller includes one or more data storage devices and one or more processors. The one or more data storage devices are configured to store data corresponding to one or more random variables associated with operation of an electrical system. The one or more processors are configured to determine a set of control values for a set of control variables to effectuate a change to the electrical system toward meeting a controller objective for economical optimization of the electrical system. The set of control values are determined by the one or more processors utilizing an optimization algorithm to identify the set of control values as a function of the one or more random variables. The one or more processors are also configured to control the electrical system based on the control values.

  • Publication number: 20200006946
    Abstract: Electrical system controllers, computer-readable storage media, and related methods for generating random variables for stochastic control of electrical systems. An electrical power system controller includes a processor. The processor is configured to generate an uncertainty metric based on observed input data, the uncertainty metric configured to indicate an uncertainty of an input variable. The processor is configured to generate a random variable based on the uncertainty metric to forecast the input data during a future period of time. The processor is also configured to generate a cost function corresponding to a cost of operating the electrical power system during the future period of time. The cost function is a function of the one or more random variables. The processor is further configured to control operation of the electrical power system during the future period of time based on an optimization of the cost function.
