    摘 要:隨著分布式資源的加速滲透,新型電力系統(tǒng)運行面臨著更大的不確定性,配電網(wǎng)電壓越限、潮流阻塞等安全問題的風(fēng)險進一步提升,據(jù)此聚合配電網(wǎng)中的海量異質(zhì)資源,充分發(fā)揮分布式資源的靈活性,有助于電力系統(tǒng)的安全穩(wěn)定運行,進一步提升電力系統(tǒng)運行經(jīng)濟性。提出了一種基于凸包辨識的主動配電網(wǎng)電壓-功率聚合方法。該方法基于配電網(wǎng)與分布式資源的運行約束,考慮了配電網(wǎng)根節(jié)點電壓對輸入功率的影響,構(gòu)建了含分布式資源的配電網(wǎng)根節(jié)點電壓-功率可行域模型,并以多面體的形式將可行域可視化,形象表征了主動配電網(wǎng)根節(jié)點電壓-功率的可行范圍。通過多規(guī)模的算例分析,驗證了所提方法的有效性和通用性。

    Abstract: With the rapid integration of distributed energy resources, the new-type power systems are experiencing heightened operational uncertainties,which led to increased risks of safety issues such as voltage over-limit and power flow blockage in distribution networks. Based on this, aggregating the massive heterogeneous resources in the distribution network and giving full play to the flexibility of distributed resources is conducive to the safe and stable operation of the power system and further improves the economic operation of the power system.This paper proposes a voltage-power aggregation method for active distribution networks based on convex hull identification. This method is based on the operational constraints of distribution networks and distributed resources. It considers the influence of the root node voltage of the distribution network on the input power, constructs a feasible region model of the root node voltage and power of the distribution network containing distributed resources, and visualizes the feasible region in the form of a polyhedron, vividly representing the feasible range of the root node voltage and power of the active distribution network. Through multi-scale case studies, the effectiveness and universality of the proposed method were verified.
    Key words: aggregation; active distribution network; convex hull identification; feasible region; distributed energy resource
