基于暂态电压严重性评估的受端电网STATCOM选址及容量优化
Location Selection and Capacity Optimization of STATCOM for Receiving-End Power Grid Based on Transient Voltage Severity Assessment
当前受端电网电压支撑能力下降,亟需针对系统暂态电压安全问题进行动态无功功率优化配置。首先给出了STATCOM配置用受端电网预想场景集和故障集的生成方法;然后,构建基于暂态电压严重性的灵敏度指标进行STATCOM的优化选址;其次,构建了以配置成本为目标函数、计及暂态电压稳定约束的容量优化模型,并使用粒子群优化算法进行求解得到配置结果。通过对广东电网应用案例开展STATCOM优化配置,结果证明了所提方法的有效性。
At present, the voltage support capability of receiving-end power grid is decreasing, so it is urgent to optimize the dynamic reactive power configuration for the security of the transient voltage of the system. Firstly, the generation method for the scene and fault set of the receiving-end power grid for STATCOM configuration is provided. Secondly, a sensitivity index based on the transient voltage severity is constructed to optimize the location of the STATCOM. Thirdly, a capacity optimization model with configuration cost as the objective function and considering transient voltage stability constraints is constructed. Then, the optimal configuration scheme is obtained by using particle swarm optimization algorithm. Finally, through the simulation calculation of STATCOM optimization configuration of Guangdong power grid, the results show that the proposed method is effective.
