Dynamic economic dispatch of power systems by multi-pass dynamic programming
The purpose of this research is to improve area Automatic Generation Control (AGC) by using the Multi-Pass Dynamic Programming developed in this research. The AGC of power systems coordinates the Load Frequency Control problem and the Economic Dispatch problem together to form a dynamic optimal …

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 …

Decentralized frequency control of power systems with deep penetration of wind-based generation
… into the power grid is calling for more control and regulation of the power system dynamics. In particular, the automatic generation control, which is responsible for maintaining the nominal system frequency and the scheduled real power interchange, needs to be modified to include …

Impact evaluation of cyber-physical uncertainty on power systems
… on the dynamic performance of 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 …

Cyber-attack detection and resilient state estimation in power systems
… We evaluate the eectiveness of this approach on Automatic Generation Control (AGC), a vital control mechanism in today's power grid. After an attack has been detected, mitigation procedures must be put in place to allow continued reliable operation or graceful degradation of the power grid. To …

Countering Cybersecurity Vulnerabilities in the Power System
… injection attacks and give a 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 …

Effective utilization of flywheel energy storage (FES) for frequency regulation service provision
… constitute a significant portion of new power generation capacity additions. As the outputs of renewable generation resources are function of the climatic conditions at their geographic locations – and over which the resource operators have no control – and the current renewable technologies …

Optimal Management and Sizing for Battery Energy Storage Systems for Grid Applications
… market frequency and energy, BESS cost, and the Automatic Generation Control (AGC) signal. Additionally, a sensitivity analysis was applied to assess BESS efficiency. Thus, a comprehensive sizing model was considered in order to observe the effects of these uncertainty parameters on the size of …

Enhanced automatic generation control with uncertainty
… One process that helps in achieving 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 …
