Embodiment 1

[0015] The second phase of wind storage integration project of Azuoqi wind farm adopts outdoor container energy storage system, which includes energy storage battery pack container, bidirectional converter (PCS) container and step-up transformer, and is characterized in that the energy storage battery pack The battery of the container is a lithium electronic energy storage battery. After the AC and DC conversion of the lithium electronic energy storage battery is completed by the PCS container, the voltage is boosted to 35KKV, and connected to the 35KV bus of the substation. The PCS device can realize two-way flow; in the charging state, the PCS acts as a rectifier The device converts the electrical energy from AC to DC and stores it in the storage device; in the discharge state, the PCS acts as an inverter to convert the electrical energy stored in the energy storage device from DC to AC and transmits it to the grid.

[0016] The container adopts a standardized container with ...

Abstract

A container type energy storage system for a wind power generation is disclosed. The container type energy storage system comprises an energy storage battery pack container, a bidirectional power conversion system (PCS) container and a boosting transformer, wherein the battery of the energy storage battery pack container adopts a lithium ion energy storage battery; after the lithium ion energy storage battery is subjected to completion of alternating current/direct current conversion through the PCS container, the lithium ion energy storage battery is boosted to 35KKV and connected to a 35KV busbar of a substation; the PCS apparatus can realize bidirectional flow; under a charging state, the PCS is used as a rectifying apparatus for converting the alternating current into direct current to be stored in a storage apparatus; and under a discharging state, the PCS is used as an inverter for converting the direct current stored by the storage apparatus into alternating current to be transmitted to a power grid. According to the container type energy storage system, an energy storage technology with large scale, long service life, high efficiency and low cost is realized; the electric energy quality of new energies in grid connection is greatly improved, a certain energy loss caused by limited power is reduced, and the influence on the power grid caused by large-scale new energy power generation and grid connection is relieved.

Description

technical field [0001] The invention relates to the field of wind power generation equipment, in particular to a container-type energy storage system. Background technique [0002] With the increasingly serious energy crisis, the development of sustainable and environmentally friendly new energy has become a hot spot of global concern. As a clean, efficient and renewable new energy, wind power has become the focus of new energy development in various countries. The development and utilization of renewable energy such as wind energy is an important part of the national energy development strategy. However, wind energy has the characteristics of intermittent and randomness, which has a certain impact on the grid. With the continuous increase of wind power grid-connected capacity, the impact of wind power on the grid is also increasing. Due to the problem of high-power and high-efficiency energy storage, there is no The bottleneck caused by being well resolved, and the problem...
