考虑运行和网架风险的配电网运行方式制定及优化

Establishment and Optimization of Distribution Network Operation Mode Considering Operation and Grid Risk

传统配电网运行方式制定和优化并未充分考虑配电网运行过程中的风险因素。为了保证配电网运行方式的最优,提出了一种考虑运行和网架风险的配电网运行方式优化方法,并在此基础上实现了正常运行方式的制定。该模型将配电网运行风险和网架风险纳入到运行方式优化中,同时利用权重将多目标优化模型简化为单目标优化模型。算例的计算结果证明了提出的配电网运行方式优化方法的正确性,同时还能满足用户降低运行风险以及网架风险的要求。

Traditional establishment and optimization method of distribution network operation mode doesn＇t take into consideration risk factors. In order to make the distribution network operate in the optimal operation mode, this paper proposes an establishment and optimization method of the distribution network operation mode considering the running risks and weak link. Based on which the normal operation mode is established, and the running risks and weak link of the distribution network is taken into account in the model for optimizing the operation moed. In addition, the proposed multi-objective optimization model is simplified to a single objective optimization model using weights. The calculation result of a numerical example proves the validity of the proposed optimization method of the distribution network operation mode, meeting user demand for the operation risk and weak link.
