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.
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.
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.
A smart grid technology is designed to achieve a high penetration of photovoltaic (PV) systems into homes and businesses, it is an intelligent system capable of sensing system overloads and rerouting power to prevent or minimize a potential outage of power over the grid.
Grid-interactive solar PV inverters must satisfy the technical requirements of PV energy penetration posed by various country's rules and guidelines. Grid-connected PV systems enable consumers to contribute unused or excess electricity to the utility grid while using less power from the grid.
Renewable energy source integration with power systems is one of the main concepts of smart grids. Due to the variability and limited predictability of these sources, there are many challenges associated with integration. This paper reviews integration of solar systems into electricity grids.
