Distributed multiport converters for integration of renewables, storage systems and loads while enhancing performance and resiliency of modern distributed networks (iPLUG)

现代配电网正面临着重要的挑战，例如需要在低压和中压配电网中整合大量的可再生能源和存储，加强配电网的使用以避免建设新的线路，连接不同电压水平的交流或直流（交流或直流）供电的几个负载。为了应对上述挑战，iPLUG提出了基于多端口转换器的新型电力电子解决方案的开发，以增强多种可再生能源、储能系统和负载的集成。拟议中的转换器安装在几个最佳位置，可以促进可再生能源的大规模整合，避免电网拥堵，并允许为最终用户和配电网提供功能。该项目研究了系统级方面和详细的电力电子创新解决方案，用于低压和中压应用。iPLUG分为六个工作包。阐述了系统的设计，包括概念定义、规格、尺寸和位置优化。设计了多端口电源变换器及其内部控制，并在实验室进行了实验验证。考虑到多个多端口转换器在几个用例中的使用，并在实验室中验证了这些概念，还提出了整体系统控制。进行了技术、经济、社会和环境影响分析。该项目财团由五个核心研究机构组成，由提供关键需求和案例研究并分析项目结果的相关公司提供支持

Modern distribution grids are facing important challenges such that the need to integrate massive amounts of renewables and storage in the low and medium voltage distribution grid, enhance the usage of distribution networks to avoid construction of new lines, connect several loads at different voltage levels supplied with alternating or direct current (AC or DC). In order to address the challenges described, iPLUG proposes the development of novel power electronics solutions based on multiport converters in order to enhance the integration of multiple renewable sources, energy storage systems and loads. The proposed converters, installed in several optimal locations, can facilitate a massive integration of renewable avoiding grid congestion and allowing the provision of functionalities to both the endusers and the distribution grid. The project studies both system-level aspects and detailed power electronics innovative solutions for low and medium-voltage applications. iPLUG is organized in six work packages. The system design is addressed, including concept definition, specification, sizing and location optimization. Multiport power converters and their inner control are designed and validated experimentally in the laboratory. The overall system control is also proposed, considering the usage of multiple multiport converters in several use cases and validation the concepts in the lab. Technical, economic, social and environmental impact analysis is conducted. The project consortium is formed by a core of five research institutions, supported by relevant companies which provide key requirements and case studies and analyse the project results
