First, the mathematical model of wind power hybrid energy storage system is established based on exergoeconomics.
Can 'wind power + energy storage' improve reliability and stability of wind power system?
Therefore, the ' wind power + energy storage ' system can improve the reliability and stability of wind power system. At present, for the coordinated operation of ' wind power + energy storage ', domestic and foreign experts have carried out a series of exploratory work 14, 15, 16.
How can energy storage systems be compared more accurately?
In order to compare the losses of different energy storage systems more accurately, the optimization direction of maximizing exergy efficiency and minimizing exergetic cost is explored. In this study, the system is evaluated in an exergoeconomic environment. The unit cost C i of different energy storage systems is shown in Fig. 9.
How can a wind storage hybrid system improve power quality?
By simulating the wind storage hybrid system with different wind speed, speed and tip speed ratio, based on the the system exergy efficiency and the state of charge of the battery, the charge and discharge status of different energy storage devices and batteries is changed to improve the power quality of the wind power system.
Can Exergoeconomics judge production-storage-use characteristics of 'wind power + energy storage'?
