Distributed frequency emergency control with coordinated edge intelligence

• A local power loss ∆ P estimation approach for frequency emergency control is proposed, and the coordination of distributed loads achieved by edge intelligence IoT technologies. The proposed LFC method can achieve accurate coordinated load shedding while reducing communication burden. cyber-physical architecture implementation an industrial system are elaborated, discussing practical issues. Base on IEEE 24-bus east China System, numerical simulations, hardware experiments, comparative studies conducted. Developing effective strategies to arrest grid drop in case severe contingencies important requirement. While responsive primary have been studied literature, relies high-speed or centralized threshold setting. They might be cost-prohibitive not sufficiently fast contingencies, like fault ultrahigh voltage direct current (UHVDC) lines China. In this paper, a Internet-of-Things (IoT) enable provide support grids. parameter-setting center decision-making at level described detail. Based typical test real bulk China, simulations experiments conducted verify performance approach. Further, named Grid Sense implemented explicitly described, real-world issues implementing analyzed.
