Optimization of grid-connected wind and battery energy storage system
Department of Electrical and Computer Engineering
This paper implements optimal control strategies in the scenario of a battery energy storage system connected to the electric grid together with a wind turbine. A simplified model for a battery is first developed, along with a state equation model of the system. Optimal control is used to minimize the difference between the actual battery power and the given reference power. The battery is connected to the grid through a buck converter, and the optimal control solution is used to calculate the necessary duty cycle to achieve the desired results. Inequality constraints are added to ensure that the simulation is a realistic model of the behavior of a battery. The control strategy is also demonstrated experimentally with a battery and sample grid system.
