New Data on Energy - Wind Farms from Northeast Electric Power University

Researchers at Northeast Electric Power University have developed a new strategy for shared energy storage, which integrates wind-storage bilateral transactions and ancillary peak-shaving services to address the high investment costs, low utilization, and long payback periods of single-service energy storage. The strategy leverages multi-service synergy to improve energy storage utilization and economic benefits while optimizing wind farm bidding strategies in the day-ahead market. A revenue maximization model was developed based on the Weibull distribution of wind power, incorporating capacity degradation costs. The model was tested through case studies, which demonstrated a significant increase in benefits for shared energy storage operators and wind farms.

Key Takeaways:

• The research proposes a shared energy storage strategy that integrates wind-storage bilateral transactions and ancillary peak-shaving services to address the high investment costs, low utilization, and long payback periods of single-service energy storage.
• The strategy leverages multi-service synergy to improve energy storage utilization and economic benefits while optimizing wind farm bidding strategies in the day-ahead market.
• A revenue maximization model was developed based on the Weibull distribution of wind power, incorporating capacity degradation costs.
• Case studies demonstrated that the proposed model increases shared energy storage operator and wind farm benefits by 2.35%, 5.69%, and 6.81%, respectively, while shared energy storage revenue rises by 255.46% compared to ancillary services alone.
• The model reduces wind farm leasing costs, mitigates wind curtailment and grid deviation penalties, and enhances overall economic efficiency.
• The research provides a structured framework for wind-storage collaboration, offering theoretical insights into optimizing energy storage participation in electricity markets and supporting the advancement of smart grids and renewable energy integration.
