为了提高含风电的远海油气平台电网的调频能力,基于多智能体一致性理论,提出了一种以双馈感应电机为单元的风电场与海上油气平台燃气透平机组的协调频率辅助控制方法。将远海孤立电网视为多智能体系统,将风电场与海上油气平台燃气透平机组看作智能体,基于海上电力网络的拓扑信息构建多智能体系统通信网络,实现各智能体之间的信息交互;分别建立风电场和海上油气平台燃气透平机组的频率辅助控制多智能体模型,基于多智能体一致性算法给出控制器结构,基于多智能体通信网络实现风电场智能体与海上油气平台燃气透平机组智能体之间的频率协调控制;通过线性二次型最优控制对控制器参数进行优化。基于算例仿真验证所提控制方法的有效性,结果表明所提协调频率辅助控制方法能有效提高系统的频率调节能力,抑制频率波动。
In order to improve the frequency regulation capability of offshore oil and gas platform power grid containing wind power,a coordinated frequency auxiliary control method of wind farm and gas turbine unit on the offshore oil and gas platform is proposed based on the multi-agent consistency theory,inside the wind farm a double-fed induction generator is taking as a unit.The offshore isolated power grid is regarded as a multi-agent system,the wind farm and the gas turbine unit on the offshore oil and gas platform are regarded as agents.Based on the topological information of the offshore power network,the communication network of multi-agent system is constructed to realize the information interaction among agents.The multi-agent models of frequency auxiliary control for wind farm and gas turbine unit on offshore oil and gas platform are established respectively.The controller structure is given based on the multi-agent consistency algorithm,and the frequency coordination control between wind farm agents and gas turbine unit agents is realized based on the multi-agent communication network.The parameters of the controller are optimized by linear quadratic optimal control.The effectiveness of the proposed control method is verified by a simulation example.The results show that the proposed coordinated frequency auxiliary control method can effectively improve the frequency regulation capability of the system and suppress frequency fluctuations.
