摘　　要：提出了一种考虑输电裕度的电源建设方案优化算法。在该算法中模型中,以最大支路负载比的最小值为目标函数,以节点功率平衡作为等式约束,以支路载流能力、主变潮流方向、新并网电源的电源边界等作为不等式约束。为了得到电源建设模型的优化结果,采用了基于稀疏技术的原-对偶内点法进行求解。实际运行算例表明,与传统电源建设优化方法相比,提出的规划方案不仅可满足能源政策更新带来的输电裕度问题,也可使得该地区的支路负载比均匀分布。The uncertainty of power transmission margin is aggravated by the increase and updating of energy policy, which brought certain difficulty to power supply construction. In this paper, an optimization algorithm for power construction scheme that considers the transmission margin is proposed. In this algorithm, the minimizing of the maximum branch load ratio is taken as the optimization objective function, and the node power balance is taken as the equality constraint, and the branch current carrying capacity, the main transformer power flow direction and the power boundary of the new grid-connected power supply as the inequality constraints. In order to obtain the optimal results of power supply construction model, a primal-dual interior point method based on sparse technology is used in this paper to solve the problem. Actual operation results show that, compared with the traditional power supply construction optimization method, the proposed planning scheme not only satisfies the transmission margin problem caused by the energy policy updating, but also makes the branch load ratio uniformly distributed in this area, which has more accurate economic and technical guidance.
