Hierarchical Control of Thermostatically Controlled Loads for Primary Frequency Support [PDF]
This paper proposes a hierarchical control of thermostatically controlled loads (TCLs) to provide primary frequency control support. The control architecture is composed of three levels. At the high level, an aggregator coordinates multiple distribution substations and dispatches the primary reserve references.

Wind Turbines Emulating Inertia and Supporting Primary Frequency Control
The increasing penetration of variable-speed wind turbines in the electricity grid will result in a reduction of the number of connected conventional power plants. This will require changes in the way the grid frequency is controlled. In this letter, a method is proposed to let variable-speed wind turbines emulate inertia and support primary frequency ...

A Novel Decentralized Responsibilizing Primary Frequency Control [PDF]
There is an emerging need to prioritize remedial frequency control measures closer to the source of an imbalance event. This approach, referred to herein as responsibilization, is challenging to achieve within the conventional operating times of Primary Frequency Control (PFC) and therefore novel methods are sought.

Analysis of Responsibilization within Primary Frequency Control [PDF]
The emerging need to prioritize remedial frequency control measures closer to the source of an imbalance event, referred to as responsibilization, is being acknowledged. As responsibilization is inherent within secondary frequency control, novel primary frequency control (PFC) approaches to incorporate responsibilization are being proposed in ...

Impact of frequency estimation for VSC-based devices with primary frequency control [PDF]
This paper presents a comparison of the performance of frequency control devices considering different techniques to estimate the frequency deviation signal. We consider three estimation techniques, namely the center of inertia (COI), the frequency divider (FD) formula, and the phase-locked loop (PLL).

Challenges of Primary Frequency Control and Benefits of Primary Frequency Response Support from Electric Vehicles [PDF]
As the integration of wind generation displaces conventional plants, system inertia provided by rotating mass declines, causing concerns over system frequency stability. This paper implements an advanced stochastic scheduling model with inertia-dependent fast frequency response requirements to investigate the challenges on the primary frequency control

Decentralized Primary Frequency Control in Power Networks
We 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.

Model for Frequency Dynamics in an Islanded Microgrid and Primary Frequency Control Based on Disturbance Compensation [PDF]
Islanded microgrids have low inertia due to a large penetration of non-inertial inverter based power sources. In such systems, the primary frequency controller (PFC) faces the issue of a higher rate of change of frequency (RoCoF) and large peak frequency deviation in case of a sudden change in load or generation loss. The frequency control becomes more
