电压调节、频率恢复和无功/有功功率共享是微电网二次控制的关键任务，特别是在孤岛运行模式下。由于微电网中的传感器和通信链路易受噪声影响，因此设计抗噪声的二次电压和频率控制具有重要价值。本文提出了一种用于交流微网二次控制的最小方差控制方法，可以有效地实现噪声衰减、电压/频率恢复以及无功/有功功率共享。为此，将非线性广义最小方差（NGMV）控制方法引入孤岛微网二次控制系统。在MATLAB环境下对两个微网试验系统进行仿真，验证了所提控制方法的有效性。
Voltage regulation, frequency restoration, and reactive/active power sharing are the crucial tasks of the microgrid's secondary control, especially in the islanding operating mode. Because sensors and communication links in a microgrid are subject to noise, it is of paramount value to design a noise-resilient secondary voltage and frequency control. This paper proposes a minimum variance control approach for the secondary control of AC microgrids that can effectively perform noise attenuation, voltage/frequency restoration, and reactive/active power sharing. To this end, the nonlinear generalized minimum variance (NGMV) control approach is introduced to the islanded microgrid's secondary control system. The effectiveness of the proposed control approach is verified by simulating two microgrid test systems in MATLAB.
