This paper studied the operation of coordinated inverter control deployed in two diferent low-voltage test networks with an existing 30% PV penetration comprised of passive inverters.
One of the main challenges in microgrids based on voltage source inverters is power sharing control, or in other words, balancing active power and reactive power [48, 49]. A large number of researchers are always looking into different kinds of controls to achieve better performance in microgrids.
The primary objective for deploying coordinated inverter control (CIC) is to exploit its efectiveness in regulating voltage.
Coordinated inverters with bidirectional communication capability can be used for tasks beyond local voltage control. In particular, they could allow the VPP aggregator to respond to energy mar- ket price signals or provide ancillary services. However, there is a problem that is seldom mentioned in this context.
