Solar power distribution system in the communication room

Are communication and control systems needed for distributed solar PV systems?

The existing communication technologies, protocols and current practice for solar PV integration are also introduced in the report. The survey results show that deployment of communication and control systems for distributed PV systems is increasing.

Can distributed solar PV be integrated into the future smart grid?

In the report, the communication and control system architecture models to enable distributed solar PV to be integrated into the future smart grid environment were reviewed. The existing communication technologies, protocols and current practice for solar PV integration are also introduced in the report.

What communication technologies are used for distributed solar PV system integration?

Distributed solar PV systems generally are connected to HAN and NAN/FAN network, which is the so-called “last-mile” communication network. The following sections give an overview of existing and widespread communication technologies used for distributed solar PV system integration.

How do distributed solar PV systems work?

This section focus on the existing concepts for integrating and coordinating the operations of the distributed solar PV systems. Currently, most PV systems are connected to the grid usually with a “fit and forget” principle. PV systems operate autonomously through the advanced solar inverter functions.

What are the communication & control functions used in solar projects?

The PV communication & control functions applied in the present solar projects in USA include: Active power of PV system: Required in some island systems, not yet in mainland. Voltage at grid coupling point of PV system: Required in some specific feeder conditions with relative high penetration. Curtailment/feed in management: Not yet required.

Do energy storage subsystems integrate with distributed PV?

Energy storage subsystems need to be identified that can integrate with distributed PV to enable intentional islanding or other ancillary services. Intentional islanding is used for backup power in the event of a grid power outage, and may be applied to customer-sited UPS applications or to larger microgrid applications.
