Control Systems And Methods For Economical Optimization Of An Electrical System Including Battery Degradation
The present disclosure is directed to systems and methods for economically optimal control of an electrical system. Some embodiments employ generalized multivariable constrained continuous optimization techniques to determine an optimal control sequence over a future time domain in the presence of any number of costs, savings opportunities (value streams), and constraints. Some embodiments also include control methods that enable infrequent recalculation of the optimal setpoints. Some embodiments may include a battery degradation model that, working in conjunction with the economic optimizer, enables the most economical use of any type of battery. Some embodiments include techniques for load and generation learning and prediction. Some embodiments include consideration of external data, such as weather.

- 1. A controller of an electrical system that includes a battery, the controller comprising:
a communication interface to receive a current state of a battery of an electrical system; and one or more processors to:
determine battery degradation of the battery for a time period, based on the current state of the battery;
determine a battery degradation cost based on the battery degradation for the time period; and
control the electrical system via the communication interface to optimize operation of the electrical system, based on one or more cost elements associated with operation of the electrical system, the one or more cost elements including the battery degradation cost.
- 18. A method of a controller of an electrical system including a battery, the method comprising:
receiving from a sensor of an electrical system a current state of a battery of an electrical system; determining a battery degradation of the battery for a time period of an upcoming time domain, based on the current state of the battery; determining a battery degradation cost based on the battery degradation of the battery for the time period; and controlling the electrical system to optimize operation of the electrical system during the upcoming time domain, based on the battery degradation cost.
