On Area Control Errors, Area Injection Errors, and Textbook Automatic Generation Control
IEEE Transactions on Power Systems, 2021We reexamine and critique the classical area control error concept used in automatic generation control, and propose a new error signal termed the area injection error. Unlike the ACE, the AIE uses direct measurement of generator power levels, yielding improved AGC performance in the presence of bias uncertainty and nonlinearity in generator turbine ...

Error control strategy in ultrasonic Body Area Networks
China Communications, 2016Recently, ultrasonic waves had been introduced as the transmission medium in Body Area Networks (BANs) to reduce the incalculable damage caused by radio waves. However, the communications based on ultrasonic waves suffer from poor propagation of signals in air and consume too much energy.

Autoregressive moving average modeling of area control error
2017 IEEE Power & Energy Society General Meeting, 2017Area control error (ACE) is a quantity used by balancing authorities to perform frequency regulation in bulk power systems. Recently, increased variations in ACE were seen in second-to-second timescale as a result of rising volatile power generation such as wind.

IEEE Transactions on Power Systems, 2020
Air conditioners (ACs) have been widely considered as one of the most important reserve resources for power systems. However, few attentions have been given to inverter ACs (IACs), which account for a larger share nowadays and show more suitable characteristics than regular ACs to provide reserve.

A new error handling algorithm for controller area network in networked control system
Computers in Industry, 2013An effective error handling mechanism plays an important role to ensure the reliability and robustness of the application of controller area network (CAN) in controlling dynamic systems. This paper addresses a new online error handling approach or named per-sample-error-counting (PSeC) technique that tends to replace native error handling protocol in ...

Message response time distribution analysis for Controller Area Network containing errors
2015 Chinese Automation Congress (CAC), 2015Controller Area Network (CAN) is a widely used fieldbus protocol in various industrial applications. In order to understand the network behaviors under errors for optimal design of the networked control systems, the messages response time (MRT) of the CAN nodes need to be analyzed.

Using EASY5 to investigate filtering of power system area control error
Proceedings of 26th Southeastern Symposium on System Theory, 2002The area control error (ACE) is an indication of the mismatch between generation and load demand of a power system. This signal is an integral part of the automatic generation control (AGC) system which seeks to match area generation and load on a moment to moment basis.
