Solar energy grid integration systems-energy storage segis-es

What is solar energy grid integration systems (Segis)?

It is expected that these solutions will help to push the “advanced integrated system” and “smart grid” evolutionary processes forward in a faster but focused manner. Solar Energy Grid Integration Systems (SEGIS) concept will be key to achieving high penetration of photovoltaic (PV) systems into the utility grid.

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.

What is a Segis inverter/controller?

Development of the inverter/controller is a central element of the SEGIS program. The inverter transforms dc power from the PV array to grid-quality ac power. Depending upon the system architecture, the inverter may also charge and discharge energy storage, and may control smart loads, e.g. smart appliances, especially in residential systems.

How does Segis work?

All communication flows through this portal, including the ability to intentionally dispatch energy from the system or to request the system to operate independently of the grid. Two-way communication is also shown so that the SEGIS systems are able to report their status, including the availability of solar or stored energy, to the utility.

What factors determine the value of a solar energy grid integration system?

While cost of energy is a function primarily of system performance and life-cycle cost, the value of the energy depends on many factors, such as when it is available and the reliability of the energy. Some of the elements that factor into the value of a Solar Energy Grid Integration System are described in this section.

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.
