FAQS about Ivvo photovoltaic inverter quality

How to optimize PV smart inverters with Volt-VAR control?

A stochastic decision process is proposed to optimally place the PV smart inverters with Volt-VAr control con-sidering the uncertainties of PV generation and load demand. A set of analytical constraints are formulated in the second stage to model the impact of the Volt-VAr control with VAr priority on the voltage profile.

Should PV inverters be upgraded to a smart inverter?

For a distribution system with a high penetration level of residential PVs, selectively upgrading existing PV inverters to the smart inverters with local voltage management capability is one of the most cost-effective voltage regulation methods for system planning.

What is a smart PV inverter & control method?

In [ 26 ], researchers present a smart PV inverter and control method. A smart PV inverter can help voltage regulation by absorbing and injecting reactive power to/from the grid and can be a solution to the slow response time and cost of traditional volt–var methods such as static synchronous compensator (STATCOM), SVC, and VR.

What is a dynamic model of a PV inverter with Voltage-VAR control?

A detailed dynamic model of the PV inverter with Volt-VAr control is developed as a DLL in OpenDSS to verify the optimization results and ensure system voltage stability. The optimization has been applied on an actual distribu-tion feeder with instantaneous penetration levels as high as 200% with significant overvoltage issues.

Can a PV inverter regulate voltage effectively?

In Case 2, the PV inverter’s reactive power capacity is insufficient to regulate voltage effectively. Unfortunately, only 0.1 pu voltage regulation is accomplished.

What does ivvo stand for?

Many commercial and industrial customers are sensitive to low-voltage problems, particularly where processes are controlled by digital devices. An integrated Volt–Var control and optimization (IVVO) with supervisory control schemes are introduced .
