The Systems Integration (SI) subprogram seeks to enable the widespread deployment of secure, reliable, and cost effective solar energy on the nation’s electricity grid by addressing the associated technical and organizational challenges.
The installed cost of solar photovoltaics (PV) and concentrating solar power (CSP) have fallen significantly in recent years, spurring significant growth and accelerating deployment of solar energy systems.
The anticipated proliferation of solar power at the centralized and distributed scales emphasizes the need for timely and cost effective interconnection procedures, accurate prediction of solar resources, and monitoring and control of solar power. Moreover, the impact of solar energy on the performance and reliability of transmission and distribution power systems is becoming a larger challenge.
To proactively anticipate and address potential challenges under a scenario in which hundreds of gigawatts (GW) of solar energy are interconnected to the electricity grid, the SI program funds research that addresses these challenges in four broad, inter-related areas:
- Grid Performance and Reliability: Enhance the efficiency and reliability of electric transmission and distribution systems in a cost-effective, secure, and reliable manner.
- Dispatchability: Ensure that solar power is available on-demand, when and where it is needed and at the desired amounts, in a manner that is comparable to or better than conventional power plants.
- Power Electronics: Use devices to maximize the power output from solar power plants and interface with the electric grid (or end use circuits), while ensuring overall system performance, safety, reliability, and controllability at minimum cost.
- Communications: Develop innovative infrastructure to inform as well as monitor and control generation, transmission, distribution, and consumption of solar energy effectively under broad temporal and spatial scales.
