Abstract

The Multiport Autonomous Reconfigurable Solar Power Plant (MARS) is an integrated photovoltaic (PV) power generation and energy storage system (ESS), that is designed to connect to both alternating current (AC) transmission grids and high-voltage direct current (HVDC) links. It is a three-phase plant consisting of numerous components with a complex hardware and hierarchical control architecture. This paper presents an approach to decouple the multivariable system of MARS using a recursive reduced-order and boundary layer system methodology. This approach enables efficient computation of the control parameters for the Ll, L2, and L3 controllers. To validate the effectiveness of the proposed control strategy, cyclic tests in accordance with pre-defined performance criteria using controller Hardware-in-the-Loop (cHIL) experiments are conducted. The results demonstrate that the MARS system operates consistently under steady-state conditions. Furthermore, the dynamic response of the MARS system to various grid events is analyzed, underlining the resilience of MARS in presence of faults or loss of generation within the connected WECC system.

多端口自主可重构太阳能电站(MARS)控制系统设计与稳定性分析

multi - port Autonomous Reconfigurable Solar Power Plant (MARS)是一个集成光伏(PV)发电和储能系统(ESS)，设计用于连接交流(AC)输电网和高压直流(HVDC)链路。它是一个三相装置，由许多部件组成，具有复杂的硬件和分层控制体系结构。本文提出了一种利用递归降阶边界层系统方法对多变量系统解耦的方法。这种方法可以有效地计算Ll、L2和L3控制器的控制参数。为了验证所提出的控制策略的有效性，利用控制器硬件在环(cHIL)实验，按照预先定义的性能标准进行了循环测试。结果表明，该系统在稳态条件下运行稳定。此外，还分析了MARS系统对各种电网事件的动态响应，强调了MARS在连接的WECC系统中存在故障或发电损失时的弹性。

期刊介绍： COMPEL exists for the discussion and dissemination of computational and analytical methods in electrical and electronic engineering. The main emphasis of papers should be on methods and new techniques, or the application of existing techniques in a novel way. Whilst papers with immediate application to particular engineering problems are welcome, so too are papers that form a basis for further development in the area of study. A double-blind review process ensures the content''s validity and relevance.
