摘要

提出了一种求解动态直流最优潮流的二次规划方法。DDCOPF解决了多负荷水平的OPF,其中承诺单元的斜坡速率在两个串联负荷水平之间成为耦合。为了克服这个问题,可能需要一个非常大的矩阵。考虑的负载级别越多,使用的矩阵就越大。因此,求解可能需要较长的计算时间。因此,直流潮流优于交流潮流。为了验证该方法的有效性,采用了ieee14总线测试系统。此外,还介绍了该方法在实际系统中的应用。

Dynamic DC optimal power flow using quadratic programming
This paper proposes a quadratic programming for solving the dynamic direct current optimal power flow (DDCOPF). The DDCOPF solves OPF with multi load levels in which ramp rate of committed units become coupling between two series load levels. To overcome this problem, a very large matrix may be required. The more number of load levels are considered, the larger matrix will be used. Consequently, it may take long computation time to solve. Therefore, the DC load flow is preferable than AC load flow. To show the effectiveness of the proposed approach, IEEE 14 bus test system is used. In addition, application of the proposed approach to real system Jawa Bali 500 kV 25-bus is presented.
