高压配电网网格化规划优化模型和方法
|
摘要
新电改背景下,精细化规划成为提高电网企业效益的关键。以工程应用为目标,结合相关规划导则,提出了基于供电分区优化的高压配电网目标网架规划优化模型和方法。首先明确规划区域高压候选通道布局;然后,基于供电变电站和高压线路通道N-1供电安全性最大化,同时考虑到高压联络线路费用的最小化,在全局范围内进行供电分区的优化划分;最后针对电气上相对独立的各供电分区,采用技术经济比较方法从有限的典型接线模式中进行优选。中间年网架采用了由简到繁的典型接线模式的过渡。所提方法在保证规划方案全局最优或次优的基础上,实现了配电网分区规模的由大变小和相应规划方法的由繁变简。算例表明了该模型和方法直观、简单和实用。
Under the background of the new power system reform, fine planning has become necessary to improve the efficiency of power grid enterprises. For the purpose of engineering application, the models and methods based on power supply partition optimization are presented with relevant planning guidelines being combined for the planning of high-voltage distribution network in a target year. Firstly, the layout of candidate routes is made clear for the high-voltage lines of a planning area. Secondly, the power supply partition optimization is performed from a global perspective through maximizing the "N-1" safety of substations and line routes and also minimizing the cost of high-voltage tie lines. Finally, for each of the relatively independent power supply subareas, a wiring mode is selected from a limited number of typical wiring modes by using a technology-economy comparison method. In middle years, the transition from a simple wiring mode to a complex one is adopted. On the basis of guaranteeing a global optimal planning scheme, the distribution network scale in a subarea is changed from large to small and the corresponding planning method is transformed from complicated to simple. Results of numerical examples show that the proposed models and methods are intuitive, simple and practical.
