Abstract In this paper, a frequency-reactive power channel (FRCh) is proposed for improving the performance of conventional frequency control system in an islanded MicroGrid (MG). Using this channel, it will be possible to take advantage of reactive power management for frequency control, in addition to the conventional methods of using active power. In order to create the mentioned channel, a frequency-reactive power controller (FRC) is proposed for controlling the inverter-interfaced energy storage devices. The proposed controller reduces the MG frequency decline during contingencies. Moreover, it reduces the power of battery employed for the frequency control, while maintaining the customer voltage within permissible limits. Furthermore, this paper defines a new frequency-reactive power factor (FRF) capable of determining the best place for installation of FRC. This factor indicates the dependence of microgrid frequency on reactive power variations in each bus and identifies the buses which are more effective on the MG frequency. To demonstrate the effectiveness of proposed method and the accuracy of new factor, it is implemented on a test network in MATLAB/Simulink environment.

微电网频率控制的无功功率管理

摘要 在本文中，提出了一种频率-无功功率通道（FRCh）来提高孤岛微电网（MG）中传统频率控制系统的性能。除了使用有功功率的传统方法外，使用该通道还可以利用无功功率管理进行频率控制。为了创建上述通道，建议使用频率无功功率控制器 (FRC) 来控制逆变器接口的储能设备。建议的控制器减少了突发事件期间的 MG 频率下降。此外，它降低了用于频率控制的电池的功率，同时将客户电压保持在允许的范围内。此外，本文定义了一种新的频率-无功功率因数 (FRF)，能够确定安装 FRC 的最佳位置。该因素表明微电网频率对每条母线中无功功率变化的依赖性，并确定对 MG 频率更有效的母线。为了证明所提出方法的有效性和新因子的准确性，它在 MATLAB/Simulink 环境中的测试网络上实现。
