Communication system for solar power plants

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.

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

The survey results show that deployment of communication and control systems for distributed PV systems is increasing. The public awareness on the communication and control of grid-connected solar PV systems are raising. However the actual development of communication and control system for distributed solar PV systems are still in the early stage.

What role do communication infrastructures play in PV power plants?

As more and more PV power plants are integrated into the power grid, communication infrastructures will play an important role in the monitoring, protection and control of both PV power plants and the power grid.

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 PV power plants communicate with the CCC?

All PV power plants communicate with the CCC through the public communication network. Figure 8 shows the developed OPNET model for the grid integration of 11 PV power plants. The communication networks inside all subnetwork are configured as local area networks. Each subnetwork contains an Ethernet Switch, a workstation and a router.

What is a communication network architecture for remote monitoring of PV power plants?

This work aims to design a communication network architecture for the remote monitoring of large-scale PV power plants based on the IEC 61850 Standard. The proposed architecture consists of three layers: the PV power system layer, the communication network layer, and the application layer.
