摘　　要：受环境和气候影响,独立式风光互补发电系统运行的工作模式复杂多样,导致系统内能量不平衡,影响供电稳定性和持续性.提出一种基于蓄电池工作模式分类的协调控制策略,根据不同气象条件下的功率输入、输出关系和蓄电池工作模式将发电系统分为28种运行模式,以此实现系统各状态的平稳转换.提出直流风光互补发电系统的结构框架,分析光伏发电、风力发电和储能系统的数学模型,总结系统运行模式,提出电压分层控制策略.利用MATLAB/SIMULINK软件,对系统在不同环境条件和负载需求下的运行特性进行仿真分析,验证了所提出协调控制策略的可行性.Due to the influence of environment and climate,the operation modes of stand-alone wind and solar hybrid power generation system are complex and diverse,which leads to energy imbalance in the system and affects the stability and continuity of power supply.A coordinated control strategy based on the classification of battery operating modes is proposed to classify the power generation system into 28 operating modes according to the power input-output relationship and battery operating modes under different meteorological conditions,so as to realize the smooth transition of each state of the system.The structural framework of DC landscape complementary power generation system is proposed,the mathematical models of photovoltaic power generation,wind power generation and energy storage system are analyzed,the system operation modes are summarized,and the voltage hierarchy control strategy is proposed.Using MATLAB/SIMULINK software,the operating characteristics of the system under different environmental conditions and load demands are simulated and analyzed to verify the feasibility of the proposed coordination strategy.
