Given the ever-increased penetration of wind power generation in today's power systems, wind farms tend to operate in a dispatchable way to a certain extent by actively fulfilling dispatch orders from system operators. This paper is focused on the challenging issue of coordinating the interactive wind turbines in a wind farm, which are influenced by non-negligible wake effect, to efficiently respond to external dispatch orderx. To achieve this, a novel control strategy is proposed by: 1) effectively allocating power regulation task to individual wind turbines; and 2) utilizing the existing resources (i.e., rotational kinetic energy and pitching capability) of wind turbine to satisfy the dispatch order efficiently and reliably. Extensive case studies on both constant and variable wind speed conditions are carried out to demonstrate the effectiveness of the proposed control strategy. As a comparison, simulations results based on uniform load sharing strategy are also presented. It is exhibited that our proposed strategy has better control performance in terms of total energy harvesting and pitching activation frequency.
