中文摘要:

主动配电网的核心在于主动管理,在规划阶段综合考虑运行管理策略的影响有利于提高主动配电网规划结果的适用性。为此,考虑到主动配电网具有分层分布管理的特性,本文采用故障下游静态分区划分孤岛运行以实现故障供电恢复。同时提出了基于蒙特卡洛模拟计算停电损失费用的方法,以衡量主动配电网是否具有故障供电恢复能力对其可靠性的影响。考虑正常与故障状态下的两种控制策略,本文提出一种计及故障供电恢复策略的主动配电网电源规划双层优化模型。上层以综合成本净现值最小为目标,其中包含了停电损失计算,下层模拟正常运行状态下全局优化控制获得最优潮流。经仿真实例验证,引入停电损失费用并且考虑供电故障恢复策略的规划模型能保证规划后主动配电网的可靠性,进而整体地提升了主动配电网规划方案的经济性,具有较强的实用性及可推广性。

英文摘要:

The core of active distribution network is active management, considering the influence of operation management strategy in the planning stage of active distribution network can improve the applicability of planning results. Therefore, in view of the active distribution network characteristics of hierarchical distribution management, a new static partition principle of downstream of the fault is put forward in this paper. A strategy of active distribution network power restoration from fault is studied on account of island operation method, and then a method based on monte carlo simulation to calculate the cost of power failure is proposed to measure the influence of the fault power supply recovery ability of active distribution network on its reliability. Taking two control strategy of normal and fault conditions into account, a bi-level optimization model of distribution generation programming of active distribution network considering power restoration from fault is proposed. The upper layer aims to minimize the net present value of the comprehensive cost, which includes the power failure, and the lower layer simulates the optimal power flow under normal operation. The optimal power flow is obtained by the global optimization control under the normal state of the lower layer simulation. The simulation example verifies that the model can guarantee the reliability of the active distribution network after the planning, and further improves the overall economy of the active distribution network programming scheme, which has strong practicability and extensibility.
