System Technologies

Many tools, technologies, and resources are being developed to enable the electric grid to handle high penetrations of solar electricity generated from photovoltaic and concentrating solar power technologies. Learn more about System Technologies.

Codes and Standards

Codes and standards have been cited as major impediments to widespread use of photovoltaics within electric power systems. Effectively interconnecting high penetration solar requires careful technical attention to ensuring compatibility with the electric grid. Learn more about Codes and Standards.

Modeling and Analysis

Accurate modeling and analysis of electric power systems is key to helping utilities and other stakeholders understand the impacts of solar electricity and enable high penetrations on the grid. Learn more about Modeling and Analysis.

Distribution

New technologies and evolving customer demands are changing the way distribution systems are planned and operated. Distributed solar photovoltaic systems that interact intelligently with the utility system and nearby resources enable high penetrations of solar electricity on the grid. Learn more about Distribution. Read Distribution Case Studies.

Transmission

Continued growth in electric loads results in the need to plan for and install new generation and transmission lines. Effective transmission planning, utilization, and operation helps to enable high penetrations of solar electricity on the grid. Learn more about Transmission.

Solar Resource

The solar resource undergoes seasonal, daily, and short-term fluctuations. Accurate characterization and forecasting of the solar resource helps to enable high penetrations of solar electricity on the grid. Learn more about Solar Resource.

What is High Penetration Solar?

High penetration solar research helps DOE understand, anticipate, and minimize grid operation impacts as more solar resources are added to the electric power system.
