摘要
随着分布式电源的发展,其在配电网的渗透率也在不断攀升.针对传统的配电网运行优化方法在优化时没有考虑分布式电源出力和负荷不确定性对运行优化的影响,提出一种基于二阶锥规划的模糊优化运行模型.该模型将分布式电源出力和负荷用梯形模糊参数表示,并在锥优化模型的基础上,结合模糊机会约束构建模糊优化模型,对该模型进行清晰等价,转化为确定的优化模型.通过50节点算例系统的分析,结果验证了所提模型的有效性.
Abstract
With the development of distributed power supply,its penetration rate in the distribution network is also rising.A fuzzy optimal operation model based on second-order cone programming is proposed to solve the problem that the traditional optimization methods do not consider the influence of the uncertainty of the output and load of distributed power supply on the operation optimization.In this model,the output and load of distributed power supply are represented by trapezoidal fuzzy parameters,and a fuzzy optimization model is constructed based on the cone optimization model and combined with fuzzy chance constraints.The effectiveness of the proposed model is verified by the analysis of a 50-node example system.
