Yanghao Yu, Qingchun Hou, Yi Ge, Guojing Liu, Ning Zhang

摘要:

随着可再生能源并网对无功平衡和电压控制的挑战越来越大,无功定价比以往任何时候都更加必要。然而,由于最优交流潮流方程的非线性特性,无功电价难以有效计算。本文提出了一种同时考虑网损的有功和无功功率LMP的线性计算模型。首先,提出了一种基于增广发电转移分布因子矩阵的线性化交流潮流方程。其次,线性LMP模型推导出使用GSDF和损耗因子。LMP的制定进一步分解为四个组成部分:能量,阻塞,电压限制和功率损耗。最后,提出了一种基于该模型的LMP计算算法。IEEE-118节点系统验证了所提模型的性能。

英文摘要:

Pricing the reactive power is more necessary than ever before because of the increasing challenge of renewable energy integration on reactive power balance and voltage control. However, reactive power price is hard to be efficiently calculated because of the non-linear nature of optimal AC power flow equation. This paper proposes a linear model to calculate active and reactive power LMP simultaneously considering power loss. Firstly, a linearized AC power flow equation is proposed based on an augmented Generation Shift Distribution Factors (GSDF) matrix. Secondly, a linearized LMP model is derived using GSDF and loss factors. The formulation of LMP is further decomposed into four components: energy, congestion, voltage limitation and power loss. Finally, an iterate algorithm is proposed for calculating LMP with the proposed model. The performance of the proposed model is validated by the IEEE-118 bus system.
