文章导读

分布式电源在配电系统中的普及率逐渐提高。这给系统的规划和运行带来了新的问题和挑战。大量分布式电源输出电力的间歇性和随机性会严重危害配电系统的安全运行。因此，有必要通过考虑运行约束来评估配电系统对有间歇性的分布式电源的承载能力。为此，提出了一种考虑分布式电源输出不确定性的评估模型。该鲁棒优化模型考虑有载调压开关(OLTC)，无功补偿装置，储能系统，以及分布式电源的动态无功支撑等不同类型的调节或控制功能，并应用Bertsimas鲁棒对应项通过GUROBI求解器对其进行求解。最后，通过改进的IEEE 33节点配电系统模型验证了该方法的可行性和有效性。此外，还研究了上述调节或控制功能对提高间歇分布式发电的承载能力的影响。

Abstract

The penetration rate of distributed generation is gradually increasing in the distribution system concerned. This is creating new problems and challenges in the planning and operation of the system. The intermittency and variability of power outputs from numerous distributed renewable generators could significantly jeopardize the secure operation of the distribution system. Therefore, it is necessary to assess the hosting capability for intermittent distributed generation by a distribution system considering operational constraints. This is the subject of this study. An assessment model considering the uncertainty of generation outputs from distributed generators is presented for this purpose. It involves different types of regulation or control functions using on-load tap-changers (OLTCs), reactive power compensation devices, energy storage systems, and the reactive power support of the distributed generators employed. A robust optimization model is then attained It is solved by Bertsimas robust counterpart through GUROBI solver. Finally, the feasibility and efficiency of the proposed method are demonstrated by a modified IEEE 33-bus distribution system. In addition, the effects of the aforementioned regulation or control functions on the enhancement of the hosting capability for intermittent distributed generation are examined.
