多区域电力系统负荷频率控制的解耦计算

多区域互联电力负荷频率控制的解耦判定,用目前常用的方法计算量大,甚至难于计算。本文将这样的高阶系统解耦问题,变换为求网流技术中最小费用流问题,并采用运算简便快速、收敛可靠的OKA法求解。文中以两区域互联电力系统负荷频率控制为例进行了讨论和计算,其结果表明本文方法是可行和有效的。

THE DECOUPLJNG CALCULATION OF MULTI-AREA POWER SYSTEM LOAD FREQUENCY CONTROL

The calculating burden of the decoupling judgement of multi-area power system load frequeney centrel is very large by tranditional methods. This paper changcs the decoupling judgement problem into a minimum cost network flow problem. The solution algorithm is out-of-kilter . algorithm which is characterized by simple manipaultion, fast and reliable convergence. In the paper, we discuss and calculate the decoupling problem of two arca power system load frequency control. The results show that the proposed approach is feasible and effective.
