Primary Governing and Frequency Control in ERCOT
2007 IEEE Power Engineering Society General Meeting, 2007In an ideal world we would have all the information we need, and that information would be completely accurate. Since we do not have an ideal world we must plan and operate the power system with the information that is available. The following describes two approaches to deal with primary governing and frequency issues where some of the data and models

Primary frequency control monitoring at grid control centers
2016Although participation of large power generation units in control area’s primary frequency control is obligatory by national grid codes, the actual practice shows that it is often disabled in power plants. Since this control causes small fluctuations of unit’s power production which influences planned hourly production and causes additional wear and ...

Optimal decentralized primary frequency control in power networks
53rd IEEE Conference on Decision and Control, 2014We augment existing generator-side primary frequency control with load-side control that are local, ubiquitous, and continuous. The mechanisms on both the generator and the load sides are decentralized in that their control decisions are functions of locally measurable frequency deviations.

Impact on Interarea Modes of Fast HVDC Primary Frequency Control
IEEE Transactions on Power Systems, 2016Primary frequency control is often added to the control system of a high-voltage DC (HVDC) transmission that interconnects two nonsynchronous ac grids. As the active-power actuation lag is typically in the range of hundreds of milliseconds, the HVDC primary frequency control can be made fast enough to permit inertia sharing among the interconnected ac ...
