6 FAQs about [Microgrid reactive power control device]
Which model is used to optimize microgrids?
Model 1: Only active optimization is considered, coordinating the microgrids to affect the power flow. Model 2: Uses coordinated active and reactive power optimization, coordinating microgrids and reactive devices to affect power flow. Model 3: Based on Model 2, the reactive power support of microgrid to distribution network is further considered.
Why does a microgrid need reactive power support?
In islanded operating condition, the microgrid has to maintain the reactive power balance independently due to the absence of an infinite bus. The firmly coupled generation and utilization along with the presence of non-dispatchable intermittent renewable power sources require reactive power support.
How can the reactive output of a microgrid be adjusted?
The reactive output of the microgrid can be adjusted according to the reactive load to achieve local reactive power balance and provide certain reactive support for the upper distribution network (Fig. 28).
What is a microgrid & how does it work?
Typically, microgrids are internally coupled with multiple energy sources, including renewable energy, energy storage, loads, and microturbines, to achieve integrated scheduling and complementary utilisation of energy . Each microgrid can effectively manage and coordinate the local active and reactive power.
How can Smart Grid technology help a microgrid?
They can inject or absorb reactive power, ensuring voltage stability and compensating for imbalances within microgrids. Integrating smart grid technologies and communication systems enables the real-time supervision and regulation of reactive power assets.
