The fundamental issue with using direct AC voltage control is its inability to protect inverters against overcurrent. Thus, this paper combines AC voltage control with threshold virtual impedance. The choice of this solution is motivated by the ease of its implementation.
The improper regulation of the response time of the inverter is responsible for system instability that fluctuates the voltage, current and frequency profile of the grid may trip off DER units or shut down the power grid [, , , ].
Because the majority of renewable energy sources provide DC power, power electronic inverters are necessary for their conversion from DC to AC power. To fulfill this demand, the next generation power inverter employs innovative technologies while simultaneously assuring stability and resilience.
To operate autonomously, the control law should be changed. Power inverters need to change from following the grid to leading the grid behavior [ 1, 2, 3, 4 ]. This capability is known as the “grid-forming” concept, where power inverters are able to generate an AC voltage with a given amplitude and frequency at the PCC.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
