Recently, rapid development of battery technology makes it feasible to integrate renewable generations with energy storage system (BESS). The consideration BESS life loss for different application scenarios is economic imperative. In this paper, a novel linear calculation model BESS-integrated wind farm in scheduled power tracking proposed. Firstly, based on the cycle times-depth discharge (DOD) relation-curve, coefficient unit throughput state charge (SOC) can be determined from times-DOD relation-curve fitting function directly. Secondly, as unidirectional variation SOC single time step, calculated through integration coefficient-SOC relation function. A established self-optimal piecewise linearization primitive Thirdly, proposed incorporated optimization. Case studies demonstrate that method, item optimization effectively, and cost optimized more comprehensively.
