研究目的
To analyze a CSP-TES-PV-battery hybrid system, we develop a dispatch optimization model (H) to schedule, at sub-hourly time fidelity, the different technologies for energy generation within a detailed simulation framework (SAM’s simulation core).
研究成果
The paper concludes that hybrid systems dramatically outperform their CSP-only counterparts both from a capacity factor perspective and also economically. The presence of the battery in the hybrid system offers opportunity to participate in ancillary or real-time markets. However, such participation may only be of marginal value from a revenue standpoint for CSP-only systems.
研究不足
The computational difficulty of solving each location-market combination using the hybrid dispatch model (H) without applying any of the solution techniques described and with a solve time limit of 120 s. The annual solution times, i.e., solving all 365 instances of (H), range from 4 to 8 h, which is unacceptable for a single CSP-TES-PV-battery hybrid design evaluation. Furthermore, due to the large number of instances of (H) that reach the time limit, the dispatch solution quality is poor.
