How can regulatory changes enhance the profitability of frequency regulation with storage

Regulatory changes can significantly enhance the profitability of frequency regulation with storage. One way is by making it easier for small-scale storage operators to access wholesale electricity markets. By reducing barriers to entry and providing incentives for participation, more storage operators can engage in frequency regulation, increasing competition and potentially lowering costs. Another regulatory change that can boost profitability is establishing an intraday market for frequency regulation. This would allow for more flexibility in trading electricity based on real-time demand and supply conditions, potentially leading to higher profits for storage operators.

What are the implications of charging and discharging losses on frequency regulation profits

Charging and discharging losses have significant implications on frequency regulation profits. These losses impact the efficiency of the storage device, affecting the amount of electricity that can be stored and discharged. Higher losses result in lower overall profits from providing frequency regulation. The losses increase with the roundtrip efficiency of the storage device and the dispersion of frequency deviations. This means that storage operators need to carefully consider these factors when determining the amount of regulation power to offer to grid operators to maximize profits over the lifetime of the storage device.

How does the assumption of no battery degradation impact the analysis of frequency regulation economics

The assumption of no battery degradation simplifies the analysis of frequency regulation economics but may not reflect the real-world scenario accurately. In reality, battery degradation can have a significant impact on the profitability of frequency regulation with storage. Different storage technologies experience varying levels of degradation, which can affect the overall performance and longevity of the storage device. Ignoring battery degradation in the analysis may lead to overestimating profits and underestimating the costs associated with providing frequency regulation. It is essential for storage operators to consider battery degradation factors in their decision-making processes to ensure the economic viability of frequency regulation with storage in the long run.
