Abstract—The IEEE 1547 Standard for the interconnection of distributed energy resources (DERs) to distribution grids provisions that smart inverters could be implementing Volt/VAR control rules among other options. Such rules enable DERs to respond autonomously in response to time-varying grid loading conditions.
The grid is connected to the current regulated voltage source inverter. The grid current and voltage are monitored here and sent to the control circuit, which in turn generates the pulse width modulated (PWM) signals required for the current controlled inverter.
Convergence in terms of the cost function (21) for the 13:30–15:30 control interval under ε = 0.01 after placing 5 upgraded inverters at different depths. Placing smart inverters further away from the substation seems to be offering better voltage regulation performance (lower VDM).
Our home solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment in Polish conditions. All systems include comprehensive monitoring and control with remote management capabilities.
