Abstract

This study investigates coordinated control strategies and economic efficiency in wind power generation with energy storage systems. To address challenges such as significant output fluctuations and poor grid stability, we developed an integrated model encompassing wind turbines, energy storage devices, and the power grid. The proposed method combines predictive control with energy optimization allocation to enhance system stability and energy efficiency through multi-objective optimization of wind power forecasting, energy storage scheduling, and real-time load balancing. Furthermore, a full life cycle cost analysis is introduced to evaluate the economic impact of energy storage configurations. Simulation results demonstrate that the proposed strategy effectively reduces wind curtailment rates, improves grid-connected performance, and achieves optimal balance between investment costs and operational returns. These findings provide valuable insights for large-scale wind power integration and clean energy utilization.
