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.

Why is communication important for a solar energy grid integration system?

Communication is a critical function for the Solar Energy Grid Integration System. As PV systems increase in number and penetration, communication with the distribution system operator will be essential to ensuring safe, reliable operation. Other communication functions will be critical to optimizing system value.

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.

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.

What is integrated energy storage control & optimization?

Integrated energy storage control and optimization to maximize the benefits of the renewable energy resource. Smart, integrated system controls with algorithms and secure communication capabilities to optimize system value and energy efficiency.

What is a solar energy grid integration system?

Solar Energy Grid Integration Systems may be configured to address any combination of these market application segments and may be modular in nature. The scale of these markets is described in Table 1. PV systems generate energy with minimal environmental impact. However, a simple PV system without storage provides power only when the sun shines.
