研究目的
To analyze the operational impacts of a future U.S. power system with very high annual levels of PV (>50%) with storage.
研究成果
Using a linked capacity expansion and production cost modeling approach, we examined the economic and technical feasibility of achieving very high penetrations of PV on the U.S. power system. Simulations reveal the changes to operation that may be required to allow over 90% instantaneous penetration levels of PV alone, while accounting for various operational considerations, including unit commitment, startup costs, ramp rates, minimum generation levels, and transmission constraints.
研究不足
While this study demonstrates that PV and storage can meet U.S. power system needs at very high penetrations, results only reflect select elements of operational feasibility. Future efforts should account for the impact and costs of additional physical constraints like frequency stability and system protection, as well as institutional aspects such as market design that can impact the economics and therefore the operational outcomes.
