Dispatching Optimization Decision-Making of Active Distribution Network Based on Ordinal Optimization Theory

近年来,随着可再生能源发电技术快速发展,电网中可再生能源的渗透率不断提高。主动配电网技术被认为是实现可再生能源高效消纳的一种有效解决方案。主动配电网的调度决策深刻影响着配电网的可靠性与经济性,是主动配电网实现其应用价值的核心技术,因此研究主动配电网的调度优化决策方法具有重要的现实意义。该文针对同时具有分布式光伏、风电以及储能设备的主动配电网,建立了考虑分布式电源特性与电价影响的主动配电网调度优化决策模型,并利用序优化方法进行快速高效求解,得到主动配电网在运行周期内的最优调度策略。最后,利用某实际配电网的算例验证了该文提出的主动配电网调度优化决策方法的有效性。

With the rapid development of renew able energy generation,the technique of active distribution network is taken as an effective solution to efficiently accommodate renew able energy in recent years. The dispatching strategy of active distribution network affects the reliability and economy of distribution network deeply,which is the key technique to realize the value of active distribution network. So it is of great value to conduct the research on the dispatching optimization decision-making of active distribution network. Focusing on the active distribution network with distributed photovoltaic,wind power and energy storage devices integrated,this paper proposes a dispatching optimization decision-making model considering the characteristics of distributed generation and electricity price. Based on the ordinal optimization theory,the optimal dispatching strategy of active distribution network for certain operation period can be achieved efficiently. Finally,a case study on a real distribution network is carried out to verify the effectiveness of the proposed dispatching optimization decision-making method for active distribution network.
