Accurate monitoring helps generators verify FCAS performance, demonstrate conformance and gain greater visibility of power-system behaviour.
How do you know whether a generator is delivering the frequency control ancillary services (FCAS) it is required to provide?
For generators participating in the National Electricity Market (NEM), providing an FCAS response is only part of the challenge. They also need reliable, accurate data to demonstrate that their generating units are responding as required and to investigate performance when it does not.
As Australia's electricity system continues to evolve, effective monitoring is becoming increasingly important for generators, network operators and other participants seeking greater visibility of frequency behaviour and power-system performance.
Frequency control ancillary services help maintain the balance between electricity supply and demand and support the secure operation of the power system.
In the NEM, FCAS are one of the key services used by the Australian Energy Market Operator (AEMO) to manage system frequency and maintain supply quality. Generators and other eligible participants can provide these services by responding to changes in system frequency.
FCAS providers participate in dedicated markets and are financially rewarded for the availability and delivery of these services. This makes accurate measurement and conformance monitoring important not only for grid security, but also for demonstrating that contracted services are being delivered as required.
Providing an FCAS service requires more than simply having generation capacity available.
Generators need to be able to measure and demonstrate their response to changes in frequency. Without accurate monitoring data, it can be difficult to verify performance, identify deviations or understand what happened during a disturbance.
Effective FCAS conformance monitoring can help operators:
For generation assets operating in an increasingly complex power system, this data can also provide valuable insight beyond FCAS compliance.
Accurate measurement of generation power flow and local frequency is fundamental to FCAS conformance monitoring.
Under the National Electricity Rules, the relevant measurements need to be captured at or close to the applicable connection point. This provides the data required to assess generator behaviour and demonstrate conformance with the relevant ancillary services requirements.
The quality and accuracy of this data are therefore critical. A monitoring system needs to capture the required measurements reliably while also providing the recording, analysis and reporting capabilities needed by generation and network operators.
Insulect provides FCAS conformance monitoring solutions that combine the Qualitrol IDM+ monitoring platform with Autopoll software.
The system is designed to capture and analyse the power-system data required for FCAS monitoring while also supporting broader disturbance and power-quality analysis.
The modular IDM+ platform can be configured for different monitoring applications and provides high-speed recording and accurate measurement capabilities. Autopoll software provides automated polling and data collection, helping operators access and analyse recorded information.
Together, these technologies provide a monitoring platform that can support FCAS conformance as well as wider power-system monitoring requirements.
The IDM+ monitoring platform provides:
Autopoll provides:
This combination allows operators to move beyond simply collecting data and use recorded information to better understand generator and network performance.
FCAS monitoring does not have to operate as a standalone application.
The Qualitrol IDM+ platform can also be used for broader generation and power-system monitoring, including:
This provides an opportunity to use the same monitoring infrastructure for multiple applications, helping organisations gain more value from their power-system data.
