Abstract
This paper presents a method for the scheduling and operation of energy storage for wind power plants in electricity markets. A dynamic
programming algorithm is employed to determine the optimal energy exchange with the market for a specified scheduling period, taking into
account transmission constraints. During operation, the energy storage is used to smooth variations in wind power production in order to
follow the scheduling plan. The method is suitable for any type of energy storage and is also useful for other intermittent energy resources
than wind. An application of the method to a case study is also presented, where the impact of energy storage sizing and wind forecasting
accuracy on system operation and economics are emphasized. Simulation results show that energy storage makes it possible for owners of
wind power plants to take advantage of variations in the spot price, by thus increasing the value of wind power in electricity markets. With
present price estimates, energy stor
