Communication interruptions can disrupt the observability and controllability of distribution systems (DSs) after extreme events, which brings enormous challenges to the load restoration. In this paper, a measurement-correlated resilience enhancement framework for DSs is devised with emergency communication established by drone small cells (DSCs) and the innovative reconfigurable converter-based soft open point (R-SOP), while ensuring real-time voltage security. To begin with, the measurement-correlated observability and controllability of the faulted DSs are clarified. rgb0.00,0.00,0.00The power scheduling and mode control models of R-SOP are formulated to promote the cost-effective resilience enhancement. Subsequently, a power flow model of the cyber-physical distribution system integrating R-SOP under faults is further developed. Furthermore, an emergency communication & R-SOP-assisted cyber-physical coordinated DSs restoration method is put forward, rgb0.00,0.00,0.00in which, DSCs play a vital role in quickly establishing emergency communication links to accurately assess the situation and make timely decisions, effectively accelerating distribution system restoration. rgb0.00,0.00,0.00Concurrently, to solve the voltage issues caused by frequent topology changes and unpredictable renewable power, a refined Volt/VAR control method is proposed to guarantee real-time voltage security. Eventually, numerical simulations on rgb0.00,0.00,0.00two modified IEEE test systems and a ...
