This study develops a multi-stage Mixed-Integer Linear Programming (MILP) framework that jointly optimizes operational cost and asset longevity by embedding a cycle-aware degradation model into a scenario-based stochastic scheduling structure. Variability in demand, photovoltaic generation, and electricity market prices is represented through probabilistic scenario generation and reduction, ensuring operational robustness to market and resource fluctuations.

Subsequently, employing the identical dataset, the framework was applied to a real medium-voltage distribution feeder comprising 61 buses, wherein extensive sensitivity analyses were conducted under diverse operating conditions and parameter variations. The approach also incorporates a post-simulation technical loss assessment to validate the physical feasibility of the optimized strategies.

The cascaded control structure consists of power smoothing layer and voltage regulation layer. At the power smoothing layer, an improved complete ensemble empirical mode decomposition with adaptive noise (ICEEMDAN) is employed to decompose and reconstruct wind power, determining the initial active power command for BESS. Considering the current state of charge (SOC) of the BESS, a fuzzy control method is designed and applied to further modify the BESS power command, preventing insufficient response capability caused by excessive charging or discharging. At the voltage regulation layer, taking into account the total active power of the wind-storage system and voltage violations at the PCC, a fuzzy control method is developed and used to regulate the BESS reactive power, effectively managing voltage violations at the PCC of wind farms. To comprehensively consider wind farm control requirements and BESS dispatch capability, optimization models for control parameters are proposed and solved to tune the membership function parameters of the two fuzzy control model. Simulation results demonstrate the proposed control strategy can meet the requirements for wind power smoothing and PCC voltage regulation, and effectively reduce BESS active power regulation and improve BESS SOC state.
