摘要:
      配电网工程的落地依托于充足的电力廊道资源,而电力廊道规划方案的合理性也将影响到后期配电网建设的经济性。为科学指导廊道的选择,提出一种基于路径描述的配电网电力廊道规划方法。首先根据电力廊道与配电网网架之间的耦合关系,搭建电力廊道连通性模型;然后采用深度优先遍历算法获得满足廊道建设情况的供电路径集合。基于此,以电力廊道综合规划费用为廊道规划方案的评估依据,搭建了配电网电力廊道双层规划模型。最后采用嵌套离散粒子群优化算法进行优化求解,外层粒子群算法以电力廊道综合规划费用最小为优化目标,内层粒子群算法以配电网运行规划成本最小为优化目标。算例分析表明,所述模型可兼顾后期配电网建设的可行性与经济性,得到满足负荷需求的电力廊道最优规划方案,有利于提前对廊道站址进行保护,为配电网建设提供参考。
Abstract:
      The construction of distribution networks depends on available resources of power corridors. The reasonable planning of the power corridor will affect the economy of later construction of distribution networks. To scientifically guide the power corridor planning, a path description based method for power corridor planning is proposed. Firstly, a power corridor connectivity model is built, according to the relationship between the power corridor and the distribution network frame. The set of power-feeding paths is obtained using the depth-first traversal algorithm. The effectiveness of the power corridor planning scheme is evaluated by the comprehensive planning cost. Next, a bi-level optimization model of power corridors in distribution networks is formed based on the thought of decomposition and coordination. Finally, a nested discrete particle swarm optimization(PSO)algorithm is used to solve the problem. The outer layer of PSO algorithm takes the minimum cost of power corridor planning as the optimization objective, and the inner layer of PSO algorithm takes the minimum cost of distribution network planning as the optimization objective. The simulation studies show that the proposed model can give consideration to the feasibility and economy of the later distribution network construction and get the optimal planning of electric corridors satisfying the load demand, which will benefit the protection of the corridor site and provide a reference for the construction of the distribution network.
