Emerging Issues and Challenges with Integrating High Levels of Solar into the Electrical Generation and Transmission Systems
Increasing the use of grid-flexibility options (improved grid management, demand response, and energy storage) could enable 25% or higher penetration of PV at low costs (see Denholm et al. 2016). Considering the large-scale integration of solar into electric-power systems complicates the calculation of the value of solar.
