6 FAQs about [Wind power and photovoltaic power generation are unstable]

Can wind and solar power cause system disturbances?

Wind (and solar) power are not a likely cause of system disturbances. However, their associated variability and uncertainty can further complicate situations caused by faults. Disturbances can be mitigated through adapting operational practices, with the support of responses from wind (and solar) plants.

How do wind and solar power plants affect net variability?

Generally, the relative variability of wind and solar decreases as the generation of more wind and solar power plants is combined. Figure 1 shows how aggregating the output of a small set of wind turbines with a larger set has a smoothing effect on the net variability.

How does aggregation reduce the variability of wind and solar power?

within a few seconds when clouds pass or the wind stops blowing, but by aggregating geographically dispersed resources, the impact of variability on the whole system can be minimized. Generally, the relative variability of wind and solar decreases as the generation of more wind and solar power plants is combined.

Can wind and solar power plants dampen oscillations?

Wind and solar power plants are unlikely to initiate or contribute to such oscillations, but their presence can alter the number and location of online conventional generators, and, hence, the ability to dampen such oscillations. Wind and solar plants can support oscillation damping through appropriate control.

What are climate risks for wind and solar energy?

Climate risks for wind and solar resources, such as “scarce wind, scarce solar” events when low wind speed and low solar radiation occur simultaneously, can severely limit the stability and reliability of wind and solar power generation, thereby jeopardizing regional energy security.

How does a solar PV plant differ from a wind turbine?

Unlike wind turbines, solar PV plants have no physical energy storage available. As a result, the connected inverter must be operating at an AC transfer level below the DC power available from the solar panel. NREL has tested a 20 MW utility-scale solar PV plant in Puerto Rico and demonstrated FFR delivered with a delay of ~ 50–100 ms .
