Abstract

Abstract : This study presents a supervisory model predictive control (MPC) scheme for coordinated active power control of a wind farm with a centralised battery energy storage system (BESS). The control target is wind turbine generator (WTG) and BESS coordination to respond to transmission system operator power dispatching, along with equipment ageing deceleration. To alleviate the WTG mechanical fatigue and extend the BESS expected lifetime, the twist angle variation and an index introduced by a weighted ampere‐hour (Ah) throughput model are considered in the cost function. The damage equivalent load and weighted Ah throughput are used for the equipment ageing evaluation. Simulations and comparisons are conducted to demonstrate the effectiveness and applicability of the proposed MPC‐based supervisory controller design.
