以保障舰船电网稳定供应为目的，研究大扰动状态下基于多目标差分进化算法的舰船电网重构方法。该方法通过分析舰船电网在大扰动状态下的冲击规律后，计算当前舰船电网的动态势能，并以该动态势能作为基础，建立由电网负荷恢复度指标、开关操作代价、电网设备负载率等目标函数组成的舰船电网重构模型，同时设置该模型的电网负荷供电约束和电流约束条件，使用多目标差分进化算法经过种群交叉、变异和父代竞争，输出舰船电网重构模型求解新种群，实现舰船电网重构模型求解，得到舰船电网重构结果。实验表明：该方法计算大扰动冲击时，舰船电网暂态势能与其实际曲线完全重合，计算舰船电网暂态势能结果精度较高；可有效对舰船电网进行重构，重新配置舰船电网内设备开关状态，应用效果较佳。
In order to ensure the stable supply of ship power grid, the reconstruction method of ship power grid based on multi-objective differential evolution algorithm under large disturbance is studied. This method calculates the dynamic potential energy of the current ship power grid by analyzing the impact law of the ship power grid under the large disturbance state. Based on this dynamic potential energy, a ship power grid reconstruction model is established, which consists of the target functions such as the grid load recovery index, switching operation cost, electrical equipment load rate, etc. At the same time, after setting the grid load supply constraints and current constraints of the model, After population crossover, mutation and parent generation competition, the multi-objective differential evolution algorithm is used to output the ship power grid reconfiguration model to solve the new population, realize the ship power grid reconfiguration model solution, and obtain the ship power grid reconfiguration results. The experimental results show that the transient potential energy of ship power network calculated by this method coincides with its actual curve completely under the impact of large disturbance, and the calculation accuracy of the transient potential energy of ship power network is high. The utility model can effectively reconstruct the ship power grid and reconfigure the switch state of the equipment in the ship power grid, and the application effect is better.
