FAQs 6
Do PV systems participate in primary frequency regulation?
From the perspective of control strategies, the participation of PV systems in primary frequency regulation can generally be categorized into two types: load reduction control and coordinated control with PV-energy storage systems.
Can photovoltaic power generation systems with different reserve capacities participate in frequency regulation?
This strategy allows PV power generation systems with different reserve capacities to participate in frequency regulation, optimizing the load reduction controller and ensuring system frequency stability. However, this strategy cannot fully utilize the frequency modulation potential of photovoltaics with different capacities.
Why is frequency stability important in photovoltaic power generation?
To ensure frequency stability across a wide range of load conditions, reduce the impacts of the intermittency and randomness inherent in photovoltaic power generation on systems, and enhance the reliability of microgrid power supplies, it is crucial to address significant load variations.
How do photovoltaics affect grid frequency regulation?
During the participation of photovoltaics in grid frequency regulation, different frequency regulation tasks are required at different time scales. The grid demands that photovoltaics (PVs) improve steady-state frequency when facing short-term load fluctuations, while also enhancing frequency response to long-term environmental and load changes.
Can a reactive power reserve control strategy be applied to photovoltaic systems?
On a long time scale, a reactive power reserve control strategy applied to the photovoltaic side has been proposed. This strategy effectively addresses the continuous fluctuations in sunlight and load, which present random fluctuation scenarios, thereby providing robust support for mitigating system frequency fluctuations.
What is frequency regulation in power system?
Frequency regulation in power system In power systems, frequency is the continuously changing variable which is influenced by the power generation and demand. A generation deficit results in frequency reduction while surplus generation causes an increase in the frequency.
