Wind power is inherently variable and intermittent, and thus it brings great challenges to the operation of power systems. Noting that there have been considerable dispatchable sources in power systems, the coordination of wind power generation with the dispatchable sources provides the possibility to overcome the drawbacks of wind power. In this paper, the choice of coordination objective is discussed, or the output of wind power or the combine system should satisfy the requirements of the whole power systems. Based on the above principle, two examples are given. Firstly, the coordinated optimal control of wind-storage system is proposed. The objective of the coordinated control is to meet the ramp rate limit of grid code. Secondly, the coordinated optimal dispatch of wind-thermal-pumped hydro system is proposed. The objective of the coordinated dispatch is to make the output of the combined system more correlated with the system load. The optimal model and algorithm of the two examples are designed. The simulation results also validate the effectiveness of the proposed methods.
