摘要:  摘要:代表变电站技术发展趋势的智能变电站是智能电网的重要组成部分。智能变电站的配置对系统安全与经济运行具有重要影响,是值得研究的重要问题。在此背景下,研究了计及可靠性的配电系统中变电站智能化升级问题。首先,以变电站智能化升级成本和用户停电损失之和最小化为目标函数,考虑系统平均停电时间(system average interruption duration index,SAIDI)和电量不足平均值(average energy not supplied,AENS)这2个可靠性指标不超过给定阈值等约束条件,构建了配电系统中变电站的智能化升级优化模型。之后,发展了针对配电系统故障的故障清除模型,提出了评估用户停电时间的比较准确的方法。接着,对用户停电时间和用户停电损失函数进行线性化处理,得到变电站智能化升级问题的混合整数线性规划模型,并采用高效商业求解器求解。最后,以IEEE RBTS-Bus 4配电系统和丹麦某中压配电系统为例来说明所提方法的基本特征。

Abstract:  ABSTRACT:   A smart substation, which represents the development trend of advanced substation technology, is an important part of a smart grid. The configuration of smart substation could have significant impacts on the secure and economic operation of the distribution system concerned, and is an important problem to be addressed. Given this background, this paper studies the intelligent upgrading strategy of substations in power distribution system with reliability indices considered. First, we construct the intelligent upgrading optimization model of substations in power distribution system to minimize the upgrade costs of existing conventional substations and the interruption costs of customers, with considering the constraint conditions that two reliability indices including the system average interruption duration index (SAIDI) and average energy not supplied (AENS) dont exceed a given threshold. Secondly, we present a fault clearing model for power distribution system and propose an accurate assessment method for the users outage time. Then, we linearize the users outage time and outage cost function to obtain a mixed integer linear programming model for the intelligent upgrading strategy of substations, which is solved by efficient commercial solvers. Finally, the IEEE RBTS-Bus 4 distribution power system and an actual medium voltage distribution network in Denmark are served for demonstrating the basic characteristics of the presented method.
