Abstract

Green energy management is a key research focus to support de-carbonization goals by reducing harmful emissions. DC microgrid specifically helps to reach these goals as it provides numerous advantages over AC microgrid. However, challenges such as voltage regulation and power sharing mismatch must be addressed. This paper applies a novel optimization algorithm to determine the optimal droop coefficient and regulate DC bus voltage using an adaptive PID controller. The PID parameters are tuned using three techniques: Fuzzy Logic Controller (FLC), Continuous Mixed P-Norm Controller (CMPN), and Fractional Order Controller (FO). These tuning techniques essentially aim to preserve DC bus voltage at the reference value under any perturbation. Each tuning technique is integrated with the optimized droop coefficient to improve the voltage regulation and power sharing. Comprehensive simulations validate and compare the effectiveness of these controllers in achieving robust and reliable DC microgrid operation.

基于CMPN算法的带存储单元直流微电网混合优化下垂控制

绿色能源管理是通过减少有害排放来支持脱碳目标的关键研究热点。直流微电网特别有助于实现这些目标，因为它比交流微电网具有许多优势。然而，必须解决电压调节和功率共享不匹配等挑战。本文提出了一种新的优化算法，利用自适应PID控制器来确定最优下垂系数和调节直流母线电压。PID参数使用三种技术进行调整：模糊逻辑控制器（FLC），连续混合p -范数控制器（CMPN）和分数阶控制器（FO）。这些调谐技术的主要目的是在任何扰动下保持直流母线电压在参考值。每一种调谐技术都与优化后的下垂系数相结合，以提高电压调节和功率共享。全面的仿真验证和比较了这些控制器在实现鲁棒可靠的直流微电网运行方面的有效性。
