Abstract

Renewable energy systems, such as wind and solar, are intermittent, necessitating energy storage systems with efficient controllers to improve performance. This work introduces a novel control technique to a 3-level neutral point clamped (3L-NPC) converter-based brushless direct current (BLDC) machine on a variable-speed pump hydro energy storage (PHES) system, which is connected to a grid-tied hybrid solar-wind energy network. A third-order sliding mode control (TOSMC)-based field-oriented control scheme is employed on both the outer and inner loops to control the 3L-NPC-powered BLDC machine prototype, ensuring an efficient control mechanism and an integrated bidirectional power flow. Also, the TOSMC-based voltage-oriented control scheme is employed to manage the single-phase grid converter. Furthermore, maximum power is extracted from the wind energy conversion system, solar photovoltaic array, and PHES system. To evaluate the dynamic performance of the variable-speed PHES system, a rigorous study based on wind speed, solar irradiation, and load variation is performed to observe the effectiveness in motoring, generating, and stopping modes of the PHES. Moreover, the proposed controller is compared with the traditional field-oriented proportional-integral control and second-order sliding mode control on a 3L-NPC-connected BLDC machine. The performance of the BLDC-based PHES system with a 3L-NPC converter is examined in MATLAB/Simulink and validated with a laboratory prototype, demonstrating its potential as a scalable solution for hybrid renewable integration in microgrids.

单相并网混合可再生能源系统中基于smc的三阶变速PHES动态性能评价

可再生能源系统，如风能和太阳能，是间歇性的，需要具有高效控制器的能量存储系统来提高性能。本文介绍了一种新的控制技术，用于变速泵蓄能（PHES）系统上的3级中性点箝位（3L-NPC）变换器无刷直流（BLDC）电机，该系统与并网混合太阳能-风能网络相连。采用基于三阶滑模控制（TOSMC）的磁场定向控制方案对内环和外环控制3l - npc驱动的无刷直流电机样机，保证了高效的控制机制和一体化的双向功率流。同时，采用基于tosmc的电压定向控制方案对单相电网变换器进行控制。此外，从风能转换系统、太阳能光伏阵列和PHES系统中提取最大功率。为了评估变速PHES系统的动态性能，采用基于风速、太阳辐照和负荷变化的严格研究，观察了PHES在运行、发电和停止模式下的有效性。在3l - npc连接的无刷直流电机上，将该控制器与传统的面向磁场的比例积分控制和二阶滑模控制进行了比较。在MATLAB/Simulink中测试了基于bldc的带有3L-NPC转换器的PHES系统的性能，并通过实验室原型验证了其作为微电网混合可再生能源集成的可扩展解决方案的潜力。
