Control of renewable electricity networks

该研究项目旨在调查与未来可再生电网控制相关的新问题，整合EPSRC的两个研究领域：控制工程和能源网络。为了实现英国的气候目标，电力网络将需要在未来几十年进行彻底改造，这将带来一些必须提前应对的基础设施挑战。与电网相连的新技术的扩展，如集成太阳能光伏、家用电池和电动汽车，将从根本上改变电网内用于产生和储存能量的设备类型，导致电网惯性和相关稳定性的损失，而新的电网拓扑结构将随着分布式发电的增长而出现，导致当前集中式自上而下的潮流模型的下降。电网结构的这些变化将需要新的控制方案在快速的时间尺度上发挥作用，以保持稳定和一致的能源供应。该项目旨在对这些系统进行分析和建模，并将基本的控制工程和优化方法应用于设计方案，以确保系统在存在干扰的情况下保持稳定，重点是确保控制系统对电网模型中的不确定性具有鲁棒性。

The research project aims to investigate emerging issues related to the control of future renewable electricity grids, integrating two of the research areas of the EPSRC: control engineering and energy networks. In order to meet the UK's climate targets, the electricity network will require a radical transformation over the coming decades, giving rise to a number of infrastructural challenges that must be dealt with in advance. The expansion of new technologies connected to the grid, such as integrated solar PV, home batteries, and electric vehicles will fundamentally alter the types of devices used to generate and store energy within the grid, leading to a loss of grid inertia and associated stability, while new grid topologies will arise with the growth of distributed generation, leading to a decline in the current centralised top-down power flow model. These shifts in the grid structure will require novel control schemes acting at fast timescales in order to maintain stability and a consistent supply of energy. This project aims analyse and model these systems and to apply fundamental control engineering and optimisation methodologies to design schemes that ensure the systems remain stable in the presence of disturbances, with an emphasis on ensuring the control systems are robust to uncertainties in the grid model.
