Primary Frequency Control in Isolated Microgrids Using Thermostatically Controllable Loads

IEEE Transactions on Smart Grid, 2021
Hybrid renewable energy sources (RES)-diesel systems are now being considered as an economic, attractive and clean option for remote isolated microgrids, to offset diesel consumption by displacing generation from conventional units; however, system security and stability is a challenge as the penetration of RES increases.

Primary Frequency Control Characteristic of a Grid

2008 3rd IEEE Conference on Industrial Electronics and Applications, 2008
In power system, primary frequency control (PFC) is one of the important methods to maintain frequency stability. But, setting large dead band or illogically adding PFC into power system in digital electro-hydraulic (DEH) system weaken the ability of primary frequency control, that results in grid frequency stability decrease against sudden accidents ...

Primary frequency control by wind turbines

IEEE PES General Meeting, 2010
The speed of modern converter controlled wind turbines is almost completely decoupled from the grid frequency. Accordingly, wind turbines do not possess a natural response to frequency excursions. In this paper three different control concepts that enable wind turbines to participate on grid frequency control are introduced.

A new algorithm for primary frequency control with cooling appliances

Computer Science - Research and Development, 2014
Primary frequency control, also known as primary frequency response or droop, is one of the essential ancillary services guaranteeing stable operation of any power system. Provision of primary and secondary frequency control reserves creates high costs to the system operator.

Optimal decentralized primary frequency control in power networks

53rd IEEE Conference on Decision and Control, 2014
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.

Contribution of DG units to primary frequency control

2005 International Conference on Future Power Systems, 2005
AbstractThe increasing penetration of distributed generation (DG) in the electricity grid will result in a reduction of the number of connected conventional power plants, which are nowadays responsible for control of the electricity network frequency. Currently DG units do not contribute to frequency control.

Primary Governing and Frequency Control in ERCOT

2007 IEEE Power Engineering Society General Meeting, 2007
In 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

Wind Turbine Participation in Primary Frequency Control

Journal of Dynamic Systems, Measurement, and Control, 2019
Wind energy is a clean and desirable power source, but wind turbines can potentially operate to the detriment of grid stability. As wind turbine penetration increases, concerns grow regarding power intermittency and frequency regulation. These factors motivate a need for control methodologies that enable a wind turbine to support grid frequency ...

Participation of a PGU-325 in frequency primary control

Thermal Engineering, 2013
Engineering features of the main machinery for a PGU-325 power generating unit of plant no. 2 of the Ivanovskie combined cycle plants (CCPs) are given. Based on the results of preliminary tests, the upper and lower limits of the operating load range are chosen for tests of the PGU-325 on the compliance to the general frequency primary control standard ...
