安全约束下的AC输电网扩展规划

Security Constrained AC Transmission Network Expansion Planning

Soumya Das, Ashu Verma, P. R. Bijwe

摘要:

现代输电网扩展规划(TNEP)采用能够处理电压和电压稳定约束的交流网络模型。然而,这样的模型需要优化与迭代交流潮流模型,这是计算上如此苛刻,大多数研究人员忽略了至关重要的(N-1)安全约束。因此,本研究工作的目标是开发一个有效的,两阶段的优化策略来解决这个问题。在第一阶段中,解决了DC扩展规划问题,该问题提供了初始猜测以及一些非常好的算法,以减少用于AC传输和无功扩展规划的第二阶段的潮流解的数量。采用改进的人工蜂群算法(MABC)求解该最优化问题。Garver 6总线,IEEE 24总线和IEEE 118总线测试系统的静态AC TNEP结果已获得与建议和严格的方法,并在可能的情况下,与文献中报道的类似结果进行比较,以证明所提出的方法的好处。此外,多级动态AC TNEP的Garver 6总线系统的解决,以显示这种问题的方法的适用性。

英文摘要:

Modern transmission network expansion planning (TNEP) is carried out with AC network model, which is able to handle voltage and voltage stability constraints. However, such a model requires optimization with iterative AC power flow model, which is computationally so demanding that most of the researchers have ignored the vital (N-1) security constraints. Therefore, the objective of this research work is to develop an efficient, two stage optimization strategy for solving this problem. In the first stage, a DC expansion planning problem is solved which provides an initial guess as well as some very good heuristics to reduce the number of power flow solutions for the second stage of AC transmission and reactive expansion planning. A modified artificial bee colony (MABC) algorithm is used to solve the resulting optimization problem. Static AC TNEP results for Garver 6 bus, IEEE 24 bus and IEEE 118 bus test systems have been obtained with the proposed and rigorous approaches and wherever possible, compared with similar results reported in literature to demonstrate the benefits of the proposed method. Also, multi-stage dynamic AC TNEP for the Garver 6 bus system is solved to show the applicability of the methodology to such problems.
