1. A power plant for outputting power to a point of common connection with a power grid, the power plant comprising:
- a wind farm including a plurality of wind turbines configured to generate and output a first portion of the power to the point of common connection;
an energy storage system including an energy storage device configured to be charged by the wind turbines, the energy storage device configured to output a second portion of the power to the point of common connection; and
a supervisory controller coupled in communication with the energy storage system and in communication with the wind farm, the supervisory controller configured to implement a control algorithm to dynamically compute a first power reference for the first portion of the power output by the wind farm and a second power reference for the second portion of the power output by the energy storage system.

Abstract
Method, power plant, and computer program product for use in optimizing power plant power and operation. The power plant includes a wind farm, an energy storage system, and a supervisory controller implementing a control algorithm that receives information on the wind farm and on the energy storage and, based on that information, computes a power reference for the wind farm and a power reference for the energy storage. These power references optimize a given power plant objective subject to a given set of constraints on the power plant.

12. A computer-implemented method for controlling power output by a power plant to point of common connection with a power grid, the method comprising:
-
using a control algorithm to dynamically compute a first power reference for a first portion of the power output from a wind farm of the power plant and a second power reference for a second portion of the power output by an energy storage system of the power plant; controlling the energy storage system to output the first portion of the power to the point of common connection based upon the first power reference; and controlling the wind farm to output the second portion of the power to the point of common connection based upon the second power reference. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
