Regulation of blood platelet function by the AGC family of protein kinases
… cascades that result in the activation of the AGC family of Ser/Thr protein kinases (PKA, PKG and PKC). Once activated these kinase blunt platelet function through the phosphorylation of signalling proteins requested for activation. In this study, the role of AGC family kinases and their …

Enhanced automatic generation control with uncertainty
… this goal is automatic generation control (AGC), which is responsible for restoring the system frequency to the nominal value, and the real power interchange between balancing authority (BA) areas to the scheduled values. In this dissertation, we present the limitations of current AGC system …

Development and implementation of an enhanced design for automatic generation control
Automatic generation control (AGC) is the centralised short-term closed-loop control (regulation) of generating units in a control area. The main objectives of AGC are to maintain the system frequency at 50 Hz; to obtain correct tie-line interchange; and to operate each generating unit at its most …

Impact evaluation of cyber-physical uncertainty on power systems
… power systems with automatic generation control (AGC). A framework to model the deterministic and random measurement errors, and measure- ment delays, as well as the corresponding analysis methods, are developed. Along the process, the different time scales of the system dynamics, as well as the …

Countering Cybersecurity Vulnerabilities in the Power System
… case study in the Automatic Generation Control (AGC) system, which is a key control system to keep the power system's balance. However, malicious measurements can be injected to exploited devices to mislead AGC to make false power generation adjustment which will harm power system operations. We …
