摘　　要：提出基于双层一致性协议的波浪发电集群协同控制策略。以直驱式发电装置为研究对象,分析浮子机械模型并推导装置功率构成。下层控制系统通过单机双自由度控制,实现装置输出功率稳定分量和波动分量的精准控制,最大限度地转化能量的同时,实现波动分量的最小化。上层控制系统通过集群协同,在满足负荷需求和保证多单元多设备同时输出的前提下,考虑不同条件下的装置波浪吸收能力及储能能量状态,使其根据集群网络拓扑关系进行信息交互并调节下层信号。仿真结果表明,所提控制策略可动态分配各波浪发电单元输出,并逐步实现能量状态的一致化。A cooperative control strategy for wave power generation clusters based on a two-layer consistency protocol is proposed.Taking the direct-drive power generation device as the research object,the mechanical model of a float is analyzed and the power composition of the power generation device is deduced.The lower layer of control systems achieves precise control of the stable and fluctuating components of the output power of the device by means of a single-machine dual-degree-of-freedom control method,which maximizes the conversion of energy and minimizes the fluctuating component at the same time.The upper layer of control systems,through cluster collaboration,takes into account the wave absorption capacity of the device and the energy state of the storage under the premise of meeting the load demand and guaranteeing the simultaneous output of multiple units and devices,so that it interacts with information according to the topology of the cluster network and regulates signals at the lower layer.Simulation results show that the control strategy can dynamically allocate the output of each wave power generation unit and gradually realize the consistency of the energy state.
