摘要

在采用常规线性控制器的微电网中，恒功率负载的负阻抗特性和故障隔离后的瞬态恢复应力会导致系统暂态失稳、负载脱落和负载损害的可能性。随着电力分配和可再生能源集成的复杂性，需要一种具有传统控制器属性的有效控制技术;暂态缓解能力。本文提出了孤岛直流微电网电力电子接口的非线性反步控制方法，并对系统发生的各种突发事件进行了暂态稳定性分析。利用MATLAB/SIMULINK对所设计控制器的性能进行了验证。

Non-linear Backstepping based Control of an Islanded DC Microgrid with Constant Power Loads

The negative impedance characteristics of constant power loads (CPLs) and transient recovery stresses after fault isolation can cause system transient instability, load shedding and the possibility of load detriment in a microgrid if the conventional linear controllers are employed. With the complexity in the power distribution and the renewable integration, there is a need for an effective controlling technique with the attributes of the conventional controller; transient mitigating capability. This paper formulates a nonlinear backstepping control for the power electronic interfaces of an islanded DC microgrid giving a transient stability analysis for different contingencies incurring the system. The designed controller performance is validated using MATLAB/SIMULINK.
