分布式风光互补发电系统协调控制的研究

介绍一种分布式风光互补发电系统协调控制方法,对风能发电和太阳能发电的输出功率进行了分析,从风光输出功率特性和电量的角度对两种能量产生的电能进行协调控制,从而达到更加高效利用两种能量的目的。该控制方法在双BUCK电路的基础上使用两级可控开关管,处理器根据实时的风能太阳能以及负荷情况,控制这两级开关管的导通和关断,实时调节风能和太阳能的充电时间比例,从而更有效地利用两种能量。利用Matlab分别搭建了风力发电机、光伏阵列和蓄电池的模型并对该控制方法进行仿真,仿真结果验证了该控制方法的可行性和有效性,为风光互补发电更有效地应用提供了一种新的方案。

Coordination Control of Distributed Wind-solar Hybrid System

From the view of wind and solar power output,a coordinated distributed wind-solar hybrid generation system control method is established.The complementary nature of time in wind-solar hybrid generation system is studied based on the wind-solar hybrid generation system output characteristics and the perspective of state of charge,so as to achieve more efficient use of both energies.With the two controlled switch based on the two-BUCK circuit,the processor controls the two switch on and off to regulate wind and solar charging time scale,and thus more efficient use of energy.At last,the models of wind turbine,solar arrays and battery are built respectively with Matlab and the results prove the feasibility and validity of this model which is an new solution for wind-solar hybrid generation system.
