Abstract

The stable operation of DC microgrids requires robust secondary control strategies capable of ensuring accurate power sharing and bus voltage regulation, even under adverse conditions. Traditional approaches are generally based on proportional sharing according to the nominal capacities of the converters, which limits operational flexibility in scenarios requiring critical load prioritisation or maintenance strategies. This paper proposes a distributed secondary control strategy that enables individualised power allocation among converters without compromising system stability. The effectiveness of the proposed approach is validated through simulations and practical experiments under different operating conditions, including load variations, disturbances, and communication failures, demonstrating its accuracy, robustness, and applicability.

考虑通信链路故障和电流和电压控制变换器的直流微电网功率/电流共享的增强二次控制
直流微电网的稳定运行需要鲁棒的二次控制策略,即使在不利条件下也能确保准确的电力共享和母线电压调节。传统的方法通常是根据转换器的标称容量按比例共享,这限制了在需要关键负载优先级或维护策略的情况下的操作灵活性。本文提出了一种分布式二次控制策略,可以在不影响系统稳定性的情况下实现变流器之间的个性化功率分配。在负载变化、干扰和通信故障等不同运行条件下,通过仿真和实际实验验证了该方法的有效性,证明了其准确性、鲁棒性和适用性。

期刊介绍: IET Renewable Power Generation (RPG) brings together the topics of renewable energy technology, power generation and systems integration, with techno-economic issues. All renewable energy generation technologies are within the scope of the journal. Specific technology areas covered by the journal include: Wind power technology and systems Photovoltaics Solar thermal power generation Geothermal energy Fuel cells Wave power Marine current energy Biomass conversion and power generation What differentiates RPG from technology specific journals is a concern with power generation and how the characteristics of the different renewable sources affect electrical power conversion, including power electronic design, integration in to power systems, and techno-economic issues. Other technologies that have a direct role in sustainable power generation such as fuel cells and energy storage are also covered, as are system control approaches such as demand side management, which facilitate the integration of renewable sources into power systems, both large and small. The journal provides a forum for the presentation of new research, development and applications of renewable power generation. Demonstrations and experimentally based research are particularly valued, and modelling studies should as far as possible be validated so as to give confidence that the models are representative of real-world behavior. Research that explores issues where the characteristics of the renewable energy source and their control impact on the power conversion is welcome. Papers covering the wider areas of power system control and operation, including scheduling and protection that are central to the challenge of renewable power integration are particularly encouraged. The journal is technology focused covering design, demonstration, modelling and analysis, but papers covering techno-economic issues are also of interest. Papers presenting new modelling and theory are welcome but this must be relevant to real power systems and power generation. Most papers are expected to include significant novelty of approach or application that has general applicability, and where appropriate include experimental results. Critical reviews of relevant topics are also invited and these would be expected to be comprehensive and fully referenced. Current Special Issue.
