摘要

随着可再生能源所占份额的增加,电力供应的不确定性也在增加,一方面是由于可再生能源的波动,另一方面也是由于蓄意恶意攻击的威胁,由于分布式发电机组数量的增加,这种攻击可能会变得更加普遍。因此,必须以稳健的方式控制局部微电网,以确保稳定和供应安全,即使在发生干扰的情况下。为此,我们引入了一个数学模型,用于互联、物理耦合的微电网和可再生能源发电,这些微电网面临攻击风险。为了实现最佳的能源管理和控制,我们提出了一个弹性框架,该框架结合了基于模型的方法来识别正在发生的攻击和模型预测控制方案来计算鲁棒控制输入。通过数值实验验证了该方法对微电网控制的有效性。

Resilient Control of Interconnected Microgrids Under Attack by Robust Nonlinear MPC
: With the growing share of renewable energy sources, the uncertainty in power supply is increasing, on the one hand because of fluctuations in the renewables, but on the other hand also due to the threat of deliberate malicious attacks, which may become more prevalent due to the growing number of distributed generation units. It is thus essential that local microgrids are controlled in a robust manner in order to ensure stability and supply security even in the event of disturbances. To this end, we introduce a mathematical model for interconnected, physically coupled microgrids with renewable generation that are exposed to the risk of attacks. For optimal energy management and control, we present a resilient framework that combines a model-based method to identify occurring attacks and a model predictive control scheme to compute robust control inputs. We demonstrate the efficiency of the method for microgrid control in numerical experiments.
