Secondary analysis of case-control data

Statistics in Medicine, 2006
We extend the discussion of Lee et al. and others on methods for performing secondary analyses of case-control sampled data and carry out an extensive investigation of efficiency and robustness. We find that, with the exception of the 'analyse-the-controls-only' strategy for populations in which cases are rare, ad hoc methods in common usage often lead

Distributed Secondary Control of DC Microgrid via the Averaging of Virtual Current Derivatives

IEEE transactions on industrial electronics (1982. Print)
This article presents a novel distributed secondary control method for dc microgrids. The method improves existing results by considering the effects of transmission line impedances and constant power loads (CPLs) on system stability. Specifically, a new

Distributed Resilient Secondary Control for Islanded DC Microgrids Considering Unbounded FDI Attacks

IEEE Transactions on Smart Grid
The false data injection (FDI) attack is one of the most common types of cyber attacks in Microgrids (MGs), which threatens the systems’ security by destroying the integrity of the data.

Distributed Event-Triggered Fixed-Time Fault-Tolerant Secondary Control of Islanded AC Microgrid

IEEE Transactions on Power Systems, 2022
Recently, many distributed fault-tolerant (Di-FT) secondary controls have been designed to improve the robustness of the islanded AC microgrids (MGs) to actuator faults/attacks.

Coordinated Predictive Secondary Control for DC Microgrids Based on High-Order Fully Actuated System Approaches

IEEE Transactions on Smart Grid
The problem of voltage recovery and current balancing has been a hot research topic in the field of DC microgrids. How to build a model that reflects the circuit and component-level control (e.g., inner control loops) characteristics and design a ...

Distributed Round-Robin Protocol-Based Secondary Control for ESSs Under FDI Attacks

IEEE transactions on industrial electronics (1982. Print)
This article focuses on the distributed secondary control problem for energy storage systems (ESSs) under false data injection (FDI) attacks. To solve the problem, a $\boldsymbol{k}$-step attack estimation method is first proposed to estimate the unknown

Distributed Fixed-Time Secondary Control for DC Microgrid Via Dynamic Average Consensus

IEEE Transactions on Sustainable Energy, 2021
In this paper, a dynamic average consensus-based distributed fixed-time secondary control scheme is proposed for an islanded DC microgrid, to achieve both current sharing among the converters and voltage regulation of the DC bus within a fixed settling ...
