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 …

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 …

Integrating automatic generation control and demand response via a dynamic regulation market mechanism
In this thesis, a transactive control strategy is proposed to integrate flexible consumers of electricity with automatic generation control in a large AC power system with multiple interconnected areas. The proposed Dynamic Regulation Market Mechanism enables aggregated Demand Response units to bid …

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 …

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 …

AN ADAPTIVE AND SELF-COGNITIVE ACE FILTER
In Automatic Generation Control systems, the Area Control Error, (ACE) is a parameter which is used as a measure of the generation requirement of an area in a multiarea inter-connected power system. Due to normal load changes, ACE signals are random, in nature and, contain wide band noise. …

A power sharing based approach for optimizing photovoltaic generation in autonomous microgrids
… of optimizing their use. This work presents a control strategy for the optimization of available photovoltaic generation in an autonomous microgrid. The deepening penetration of rooftop solar panels motivates our case study of a microgrid with photovoltaic (PV) generators and microturbines. …

Toward distributed control for autonomous electrical energy systems
… energy systems (AEESs) by means of distributed control. We first propose a modular modeling approach that represents a general electrical energy system (EES) as a negative feedback configuration comprising a planar electrical network subsystem and a subsystem of single-port components. The …

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 …

Optimization and control of wind energy systems for grid integration
… achieved by means of some form of active power control (APC) of power generation plants. Active power control of plant power output aims to maintain the power balance between generation and consumption. Wind turbines have historically not participated in the active power control and are …

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 …
