    Abstract:

    Deploying energy storage is an effective way to solve the problem of negative peak regulation and random fluctuation of wind power output. The impact of the actual service life of energy storage on the cost of energy storage and the integration of the day-day and day-day scheduling demands of wind power grid connection are seldom taken into account into the energy storage configuration of wind farms. This paper establishes the actual service life annual value model with the consideration of the characteristics of the service life loss of electric energy storage to. According to the scheduling demand characteristics of wind power in the day-day and day-day phases, battery and supercapacitor are preliminarily determined to meet the scheduling demand of day-day and day-day phases. In order to meet the requirements of wind power grid-connected technology, the energy storage allocation strategy was carried out with the goal of annual operating income of wind farm as the target, which take into account the integrity of wind power dispatching demand in the day-day and day-day phases. An optimal allocation model of integrated energy storage for wind farm was further established, which considers the annual service life of energy storage. An actual wind farm is taken as an example for simulation analysis, and the effectiveness of the proposed energy storage configuration method is verified. The configuration method in this paper can effectively utilize the integrality of day-day and day-day demand correlation in the process of wind power grid connection, and can provide some guidance for the application of energy storage configuration in actual wind power projects.
