【摘要】：针对当前城市中低压配电网规划降损措施的选择难题,总结了配电网降损规划方案的关键步骤,建立了配电网降损规划优化决策模型。以降损规划方案全寿命周期内的综合成本、损耗电量引起的直接费用、等效GDP值与其产生碳排放对应的罚金最少作为目标函数,并考虑可靠性和安全性等约束条件,所建立的模型能够对降损措施所涉及的各方面经济效益的目标函数,以电网可靠性及电网运行安全稳定性作为效益进行综合评价。根据降损备选方案的规模不同,提出采用不同方法进行模型求解,对于规模较小的降损备选方案可采用直接比较目标函数的方式,针对规模较大的降损备选方案,采用禁忌搜索方法进行求解以提高计算效率。算例结果表明,所提出的决策方法能够对各规划方案进行优选,具有良好的可操作性和经济性。
[Abstract]:In view of the difficult problem of selecting the loss reduction measures for the current urban medium and low voltage distribution network planning, the key steps of the distribution network loss reduction planning scheme are summarized. An optimal decision model for loss reduction planning of distribution network is established. The objective function is the comprehensive cost of the whole life cycle of the loss reduction plan, the direct cost caused by the loss of electricity, the minimum penalty corresponding to the equivalent GDP value and the carbon emissions generated. Considering the constraint conditions such as reliability and safety, the established model can be used as an objective function for the economic benefits of all aspects involved in the loss reduction measures. Taking the reliability of the power network and the safety and stability of the power network as the benefit, the comprehensive evaluation is carried out. According to the different scale of the alternative scheme of reducing the loss, different methods are proposed to solve the model. For smaller loss reduction alternatives, direct comparison of objective functions can be adopted, and Tabu search method is used to solve the larger scale loss reduction options in order to improve the computational efficiency. The proposed decision-making method is able to optimize the planning schemes and has good operability and economy.
