In an islanded ac microgrid, a comprehensive algorithm of a three-phase, improved-magnitude, phase-locked-loop (3IMPL) control algorithm is developed in this paper to provide dc offset removal, steady-state error removal, and fast dynamic response. In addition, the control of the voltage-source converter (VSC) using the 3IMPL algorithm provides voltage and frequency control and elimination of harmonics of nonlinear loads. In the proposed microgrid, a solar photovoltaic (PV) array is connected to the dc link through a boost converter, and an incremental conductance technique is used for extraction of maximum power from a PV array. Due to intermittency of the PV array, a synchronous reluctance generator is used for pico-hydro generation because it is economical, ecologically sustainable, and extremely reliable and requires less maintenance. Moreover, a microgrid suffers from problems of variation in generation and continuous load fluctuations; therefore, for power balancing between the source and the load, a storage battery is connected across the dc link of the VSC through a bidirectional dc–dc converter. Test results on a prototype have verified the control strategy and are able to improve the power quality of the system at varying solar insolation and unbalance in the load.

基于 SyRG/PV/BES 的分布式孤岛微电网功率管理的鲁棒 3IMPL 控制算法
在孤岛交流微电网中,本文开发了一种三相改进幅度锁相环 (3IMPL) 控制算法的综合算法,以提供直流偏移去除、稳态误差去除和快速动态响应. 此外,使用 3IMPL 算法的电压源转换器 (VSC) 控制提供电压和频率控制以及非线性负载谐波的消除。在提议的微电网中,太阳能光伏 (PV) 阵列通过升压转换器连接到直流链路,并使用增量电导技术从光伏阵列中提取最大功率。由于光伏阵列的间歇性,同步磁阻发电机用于微微水力发电,因为它经济、生态可持续、极其可靠且需要较少的维护。而且,微电网存在发电量变化和负荷持续波动的问题;因此,为了电源和负载之间的功率平衡,蓄电池通过双向 dc-dc 转换器连接在 VSC 的直流链路上。原型机的测试结果验证了控制策略,能够改善系统在不同日照和负载不平衡下的电能质量。
