摘要

超导磁储能（SMES）系统拥有高功率密度和零电阻特性

其作为一种新型储能装置应用于电力系统是未来的必然趋势。为了更有效地平抑风电场的功率波动

以SMES和蓄电池储能系统（BESS）组成的混合储能系统（HESS）为研究对象

设计了一种分层控制策略。首先

在装置层中设计了SMES的PI加功率前馈控制器

使SMES具有稳定的直流运行电压;其次

在系统层提出了基于经验模态分解、模糊控制以及优化控制的策略

使HESS在功率分配的同时维持储能装置的荷电状态（SOC）于良好的水平

从而最大程度地补偿风电场出口的功率波动

实现风电场可靠的并网。仿真结果验证了所提出的HESS分层控制策略的有效性

为实现SMES和BESS之间不同功率、能量特性间的互补提供了新的思路。

Abstract

Superconducting magnetic energy storage（SMES） system has the characteristics of high power density and zero impedance;therefore

there is an inevitable trend for SMES to be applied in power system. In order to suppress the fluctuation of wind power more effectively

a hybrid energy storage system（HESS） based on SMES and battery energy storage system（BESS） is selected as the research object

and a hierarchical control strategy consisting of device level and system level is designed. At the device level

a PI with power feed-forward controller for SMES is proposed to maintain the stability of DC-side voltage; At the system level

a multilevel power allocation strategy for HESS based on empirical mode decomposition

fuzzy control and optimized control is proposed to achieve efficient grid connections for the wind farm

which can smooth the power fluctuation of the wind farm maximally when the state of charge of HESS is within a limit.The simulation results verify the effectiveness of the proposed hierarchical control strategies

which provide a new method to take advantage of the complementary nature of the different power and energy characteristics of the SMES system and BESS.
