考虑电压稳定的分布式发电最优配置

摘要

An optimal placement approach of distributed generation considering voltage stability was proposed. In order to form the non-linear optimization model, limited by the capability of the distribution generation, and the maximum penetration power, the approach aims at minimizing the cost of distributed company. The new model also introduced the voltage stability conditions in order to ensure the safe operation of the system. The heuristic approach was used to solve the optimization model, which can determine the optimal placement and capability of distributed generation. The results illustrate that the correctness and availability of the proposed algorithm.%提出了一种考虑电压稳定的分布式发电最优配置方法.该种方法以配电公司成本最小为目标、以分布式电源出力限制、穿透功率上限等为约束、形成非线性优化模型.新模型中还引入了电压稳定条件以确保系统运行时的稳定性.运用启发式算法对优化模型进行求解,确定分布式电源的最佳配置点和配置容量.仿真计算结果验证了上述模型和算法的有效性.
