How do photovoltaic (PV) inverters achieve active and reactive
With the development of the PV industry, the ability of inverters to accept grid dispatch has increasingly become a key feature for PV equipment manufacturers and users. String inverters
Although PV systems primarily produce real power (active power), the associated inverter systems can also provide or absorb reactive power. The inverter's ability to manage reactive power depends on the solar output and the configuration of the inverter. Data values regarding the change in reactive power throughout the day are given below.
However, in response to recent grid codes like the German BDEW, more PV inverter manufacturers have “de-rated” their inverters and now provide both a kW and KVA rating. In principle, inverters could also provide reactive power support at zero power, similar to a STATCOM.
In summary, the solar inverter's influence on reactive power in a grid-connected PV system is foundational to the modern power system's ability to accommodate high levels of renewable energy while maintaining stable, high-quality voltage profiles throughout the network.
Although PV panels themselves generate only direct current (DC) active power, the inverter plays a crucial role in controlling and injecting reactive power based on grid needs and its control strategy. Here's how the inverter influences reactive powe Inverter's role in reactive power control.
