The invention provides a high-voltage alternating-current common magnetic field type optical storage and charging intelligent charging station capable of station-network interaction, and a control method thereof. The charging station mainly comprises a high-voltage wire inlet cabinet, a high-voltage metering cabinet, a high-voltage wire outlet cabinet, a charging cabinet, a plurality of state grid billing units, a plurality of charging guns, a photovoltaic power generation unit and a lithium battery energy storage unit. The charging cabinet comprises a transformer unit, a bidirectional charging pile unit and a switching unit; the transformer unit is a multi-secondary-side winding transformer of which the primary side adopts a single delta-type winding and the secondary side adopts n paths of Y-type windings; the bidirectional charging pile unit is composed of n groups of bidirectional AC/DC modules; and the switching unit is composed of a contactor switching switch matrix. Compared with a traditional optical storage charging station, the charging station provided by the invention adopts a novel AC/DC topological framework and a fling-cut switch matrix to carry out coordination control on each optical storage charging unit, so that the load peak-valley difference during operation of the fast charging station can be efficiently balanced, the effect of peak clipping and valley filling is achieved, and economic and stable operation of the fast charging station is realized.

    本发明提供了一种可站网互动的高压交流共磁场型光储充智慧充电站及控制方法,该充电站主要包括高压进线柜、高压计量柜、高压出线柜、充电柜、若干个国网计费单元、若干个充电枪、光伏发电单元、锂电储能单元;充电柜包括变压器单元、双向充电堆单元、投切单元;变压器单元为原边采用单Δ型绕组,副边采用n路Y型绕组的多副边绕组变压器;双向充电堆单元由n组双向AC/DC模块组成;投切单元由接触器投切开关矩阵组成。相比于传统的光储充电站,本发明所提出的充电站采用新型的AC/DC拓扑架构和投切开关矩阵进行光储充各个单元的协调控制,能够高效地平衡快充站运行时的负荷峰谷差,起到“削峰填谷”的作用,从而实现快充站的经济稳定运行。
