Exact Convex Relaxation of Optimal Power Flow in Radial Networks [PDF]

, 2013
The optimal power flow (OPF) problem determines power generation/demand that minimize a certain objective such as generation cost or power loss. It is nonconvex.

Automatic Generation Control and its Implementation in Real Time [PDF]

, 2014
In power systems, the control mechanism responsible for maintaining the system frequency to the nominal value and the real power interchange between balancing authority areas to the scheduled values is referred to as automatic generation control (AGC ...

A Reinforcement Learning Approach to Undetectable Attacks Against Automatic Generation Control

IEEE Transactions on Smart Grid
Automatic generation control (AGC) is an essential functionality for ensuring the stability of power systems, and its secure operation is thus of utmost importance to power system operators. In this paper, we investigate the vulnerability of AGC to false

Effects on Load-Frequency Control of a Solar Power System with a Two-Area Interconnected Thermal Power Plant and its Control with a New BFA Algorithm

Elektronika ir Elektrotechnika, 2018
A control operation is the most important part of stabilization between load and frequency in a power system. The demand power change and the generated power change can disrupt the load-frequency balance.

Automatic Generation Controller in a Chip [PDF]

2006 International Conference on Electrical and Computer Engineering, 2006
In a power network where more than one generator is used to supply a load, power generators have to be controlled with the lowest power production cost. Network load in a power system is always varying with occasional demand surges. Even small surges create a frequency deviation in the power system and if the frequency deviation is not rapidly ...
