基于云计算的电压管理策略研究与分析

Research and Analysis of Voltage Management Strategy Based on Cloud Computing

针对分布式电源管理时复杂性高、数据量大、无功分配精度低等问题,提出基于云计算的电压管理策略。首先,根据功率分配模型对系统中有功功率和无功功率进行解耦,通过调节逆变器的输出电压,合理分配逆变器的总无功功率;其次,基于分布式云计算模型对海量电力数据进行并行处理,实现无功功率的精确分配;最后,以火电机组电压管理为例进行仿真分析,结果表明在高负荷率下每个DG均更接近其最大无功输出点。

Aiming at the problems of high complexity,large amount of data and low accuracy of reactive power distribution in distributed power management,a voltage management strategy based on cloud computing is proposed.Firstly,according to the power distribution model,the active power and reactive power in the system are decoupled,and the total reactive power of the inverter is reasonably distributed by adjusting the output voltage of the inverter.Secondly,the massive power data are processed in parallel based on the distributed cloud computing model,so as to realize the accurate allocation of reactive power.Finally,taking the voltage management of thermal power unit as an example for simulation analysis,the results show that under high load rate,each DG is closer to its maximum reactive power output point.
