摘要(Abstract)：
山区配电网存在网架结构薄弱、调节能力差等问题,降低了电网运行可靠性,不利于可再生能源的接入。为此,提出一种面向山区应用的HADN(蜂巢状有源配电网)架构,并设计涵盖多种工况的分层控制策略,主要包括微电网不平衡功率估算策略、 HADN关键设备——智能能量/信息交换基站的控制策略、多微电网多基站的控制策略。应用MATLAB/Simulink建立仿真模型,对所提出的控制策略进行仿真验证。结果表明,HADN在所提出的控制策略下能够实现多个微电网之间功率灵活调度,提升山区配电网的灵活性和可靠性。
Weak grid structures and poor regulation ability of distribution networks in mountainous areas debilitate operation reliability of power grid and are disadvantageous to the integration of renewable energies.This paper proposes a HADN(honeycomb active distribution network) structure to be applied to mountainous areas and designs a multi-layer control method under different conditions including the evaluation of the unbalance power in microgrids, the control method of the key HADN equipment, namely smart power/information exchange station and the control method of multiple microgrids and multiple base stations. A simulation model is built based on MATLAB/Simulink to verify and simulate the proposed control method. The results show that the HADN, under the proposed control method, can flexibly adjust power among different microgrids, which improves the flexibility and reliability of distribution networks in mountainous areas.
