6 FAQs about [Solar power generation regulates reactive power]

Should solar-PV inverters be regulated?

REGs could handle today's reactive power requirements; but, in the future, they should indeed be regulated to equal the efficiency of classic synchronous generators. Various control strategies may be used to offer reactive power assistance in solar-PV inverters. But, in comparison to synchronous generators, their reactive power capacity is reduced.

Does renewable generation contribute to power system voltage regulation?

Bulk system voltage regulation was provided almost exclusively by synchronous generators. However, the growing level of penetration of non-traditional renewable generation – especially wind and solar – has led to the need for renewable generation to contribute more significantly to power system voltage and reactive regulation.

Do solar PV inverters need Dynamic Reactive support?

Sometimes, external dynamic reactive support is required to assist with voltage ride-through compliance. During periods of low wind or solar resource, some generators in the plant may be disconnected from the grid. The DC voltage for solar PV inverters may limit the reactive power capability of the inverters.

Why is reactive power compensation important for solar PV systems?

The solar photovoltaic (PV) systems have gained more attention in renewable energy production due to their cost efficiency and reliability. Typically, reactive power compensation and harmonics elimination are challenging and demanding tasks for improving the efficacy of grid-connected solar PV systems.

How to improve reactive power capability of solar and wind plants?

If needed to meet interconnection requirements, the reactive power capability of solar and wind plants can be further enhanced by the adding of SVC, STATCOMS and other reactive support equipment at the plant level. Currently, inverter-based reactive capability is more costly compared to the same capability supplied by synchronous machines.

Can a solar-PV inverter provide reactive power assistance?

Various control strategies may be used to offer reactive power assistance in solar-PV inverters. But, in comparison to synchronous generators, their reactive power capacity is reduced. As a result, an ESS can be employed at the solar-PV inverter's DC-link to provide additional AP and RP assistance.
