摘要：

针对当前电力资源紧缺、控制力度不佳的问题,提出新型的风/光发电系统有功自动控制方案,该方案通过时域分析和计及交叉权重校正算法等方法,大大减少了整个自动控制系统的无功损耗。利用西门子PLC对分站进行控制,能够实时掌握系统运行状态,通过时域分析解决系统稳定性问题,利用计及交叉权重校正算法完成风/光发电有功控制。最后根据得出的灵敏度数据,通过Matlab仿真对两种有功控制系统进行对比,发现所提方法比传统方法有功输出高20%以上,增加了风/光发电系统在电力市场上的竞争力,证实了本设计的可行性。

Abstract:

A new active power automatic control scheme for wind/photovoltaic power generation system is proposed to solve the problem of shortage of power resources and poor control, which is based on time domain analysis and cross weight correction algorithm, the reactive power loss of the whole automatic control system is greatly reduced. In this study, Siemens PLC is used to control the substation, which can control the running state of the system in real time, solve the stability problem of the system through time domain analysis, and complete the active power control of wind/photovoltaic power generation by taking into account the cross weight correction algorithm. Finally, based on the sensitivity data, through Matlab simulation, the two active power control systems are compared, and it is found that the active power output of this study is more than 20% higher than that of the traditional method, which increases the competitiveness of wind/photovoltaic power generation system in the electricity market, the feasibility of the design is proved.

Key words: Time domain analysis, cross weight correction algorithm, wind/photovoltaic active power control system, Matlab simulation
