Abstract

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.

Claims24

Dependent claims

A site controller of an electrical system of a site, the site controller comprising:

a central interface configured to communicate with a central controller;
a control interface configured to communicate with one or more distributed energy resources (DERs) of an electrical system of a site, the one or more DERs controllable by one or more control values of one or more control variables delivered to the one or more DERs through the control interface;
and
one or more processors configured to:
process a proposed engagement rule set received from the central controller through the central interface, the proposed engagement rule set value configured to indicate a proposed site change in power by the one or more DERs, the site change in power comprising one or more of provision of electrical power and reduction of consumption of electrical power during a proposed period of time;
determine a predicted impact of implementing the proposed site change in power, as indicated by the proposed engagement rule set, over the proposed period of time;
and
generate an impact response message to be transmitted to the central controller through the central interface, the impact response message indicating the predicted impact.
