    摘 要:隨著微網(wǎng)技術(shù)的迅速發(fā)展,接入配電網(wǎng)的區(qū)域多微網(wǎng)系統(tǒng)已經(jīng)越來(lái)越常見(jiàn)。提出了一種基于合作博弈策略的調(diào)度方法,建立針對(duì)多微網(wǎng)系統(tǒng)的合作聯(lián)盟,先在子微網(wǎng)之間進(jìn)行功率交換,而后子微網(wǎng)再與配電網(wǎng)進(jìn)行功率交換,以提高多微網(wǎng)系統(tǒng)的經(jīng)濟(jì)性。介紹了多微網(wǎng)系統(tǒng)并對(duì)典型電源進(jìn)行建模,引入合作博弈的基本概念,并建立起并網(wǎng)型多微網(wǎng)調(diào)度合作博弈模型,合作收益則使用 Shapley 值法進(jìn)行分配。通過(guò)算例驗(yàn)證了該策略的有效性。

    Abstract: As the microgrid technology develops rapidly, regional multi-microgrid systems integrated into the distribution network have become more and more common.The paper proposes a scheduling method based on the cooperative game strategy. It first establishes a cooperative alliance for the multi-microgrid systems to make them exchange power. Then, sub-microgrids and distribution networks exchange power to improve the economy of multi-microgrid system. In the paper, the multi-microgrid system is introduced and the typical power source is modeled. Through introducing the basic concept of cooperative game theory, the grid-connection multi-microgrid scheduling model based on cooperative game theory is established, and the cooperative income is distributed by Shapley value method. The effectiveness of this strategy is verified by examples.
    Key words: multi-microgrid; scheduling; cooperative game; economic operation; Shapley value method
