| 摘要: |
| 电力系统充裕性评估对电力系统的规划建设具有重要的意义，传统的单概率性指标评估方法已经不能满足随新能源渗透率不断提升、场景复杂化、短缺事件多样化趋势下电力系统充裕性评估的需求。首先，对短缺事件以最大短缺功率等效化处理，基于改进最小二乘法进行充裕性事件分区特征点拟合，构建短缺事件集分级分类的充裕性多指标体系。然后，基于蒙特卡洛法生成多组随机短缺样本数据集，结合改进AHP-EW-TOPSIS法确定各分区指标的全局权重，并得到综合评分降落曲线。最后，根据评分降落曲线构建综合评价结果判据区间。算例以某市实际运行数据为基础进行仿真验证，结果表明，所提方法可结合主观要求和不同尺度充裕性事件的客观特性，得到更加全面、透明的充裕性评估结果。 |

| Abstract: |
| Power system adequacy assessment is of great significance to the planning and construction of a power system. The traditional single probabilistic indicator assessment method can no longer meet the needs of power system adequacy assessment with the increasing penetration rate of new energy, the complexity of scenarios, and the diversification of shortage events. First, the shortage events are equated to the maximum shortage of power, and based on an improved least squares method, the characteristic points of the shortage event partition are fitted, and a multi-indicator system for the shortage event set hierarchical classification of the adequacy is constructed. Then, multiple random shortage sample datasets are generated based on the Monte Carlo method. The global weights of the indicators in each partition are determined combined with the improved AHP-EW-TOPSIS method. Also a comprehensive score landing curve is obtained. Finally, the judgment interval of the comprehensive evaluation results is constructed according to the score landing curve. The algorithm is simulated and verified based on the actual operational data of a city, and the results show that the proposed method can combine the subjective requirements and the objective characteristics of different scales of adequacy events to obtain more comprehensive and transparent adequacy assessment results. |
