摘要/Abstract

摘要： 能源利用效率低和环境污染严重等问题促使分布式微电网技术得到快速发展。从主网侧来看，微电网作为一个可控子系统，稳定的联络线功率可以使得其外部特性被视为与时间相关且具有周期特性的等效负荷。然而，微电网内可再生能源出力的不确定性致使联络线功率稳定面临很大风险。为了解决这一挑战，提出了考虑联络线功率稳定的微电网鲁棒经济调度模型，通过协调优化其他可调度分布式电源和储能系统的出力，降低可再生能源不确定性带来的风险，从而保证微电网与主网间联络线功率的稳定性。采用列生成算法对所形成的鲁棒优化模型进行求解，在修改后的IEEE 33配电系统上进行算例验证。仿真结果表明，提出的模型可以有效地稳定微电网与主网之间的功率交换，使其具有等效负荷的外部特性。

Abstract: Low energy utilization efficiency and serious environmental pollution problems have promoted dramatic development of distributed microgrids all over the world. A microgrid is a controllable entity which can be viewed as an equivalent fixed load with sequence and periodicity from the perspective of the grid when its tie line power can be periodically stable. However, the tie line power stability can be risky due to the uncertainty of renewable energy in microgrid. To address this challenge, this paper proposes a robust economic dispatch model of the interconnected microgrid considering tie line power stability, where the power delivered from/to the grid can always be maintained at a stable level by coordinating other dispatchable distributed generators and battery energy storage system. Additionally, this model can reduce the risk from the uncertainty of renewable energy. The column-and-constraint generation method is used to solve the robust model. Simulation on a modified IEEE 33-bus distribution system indicates that the proposed model is effective to give a robust equivalent load profile of the interconnected microgrid.

Key words: microgrid, uncertainty, power stability, equivalent load, robust feasibility, column-and-constraint generation (C&CG)
