Solar Energy Grid Integration Systems

Planning and operation understanding the impacts of increasing penetration of solar energy on grid reliability and power quality and addressing the variability of solar generation and two way power flows.

Solar energy grid integration systems.

System connected in parallel to the utility grid. Initiated in 2008 the solar energy grid integration systems segis program is a partnership involving the u s. The scale of these markets is described in table 1. Solar energy grid integration systems may be configured to address any combination of these market application segments and may be modular in nature.

Doe sandia national laboratories private sector companies electric utilities and universities. The systems integration team focuses on five research areas to enable seamless integration of solar energy onto a modernized electric grid. Integration technology has become important due to the world s energy requirements which imposed significant need for different methods by which energy can be produced or integrated in addition to the fact that integration of solar energy into non renewable sources is important as it reduces the rates of. A work on the review of integration of solar power into electricity grids is presented.

A grid connected photovoltaic system or grid connected pv system is an electricity generating solar pv power system that is connected to the utility grid a grid connected pv system consists of solar panels one or several inverters a power conditioning unit and grid connection equipment they range from small residential and commercial rooftop systems to large utility scale solar power stations. The interconnection issues broadly cover the essential requirements for a small scale photovoltaic solar energy. Segis is an industry led effort to develop new pv inverters controllers and energy management systems that will greatly enhance the utility of distributed pv systems. This paper studies the major issues thrown up by the wide development of pv systems and their grid integration.

On september 1 2011 doe announced 25 9 million to fund eight solar projects that are targeting ways to develop power electronics and build smarter more interactive systems and components so that solar energy can be integrated into the electric power distribution and transmission grid at higher levels. Table 1 applications scale residential. Less than 10 kw single phase. Pv systems interconnection issues.

Projects supported under the program have focused on the complete system development of solar technologies with the. This program funds projects that advance early stage systems integration photovoltaic pv and concentrating solar thermal power technologies and reduce the non hardware costs. Part of the sunshot systems integration efforts the solar energy grid integration.
