| 摘要: |
| 微电网经济运行涉及对大量场景和方案的分析评价，区域内风电/光伏出力和负荷变化的时序性、周期性和不确定性给微电网运行带来影响。提出一种典型场景分析方法，对计算周期内的大量风电/光伏出力和负荷原始数据进行同步聚类划分，形成能够反映计算周期内历史数据特征的典型场景集；建立包含多种分布式电源和储能单元的微电网系统经济运行优化模型；针对某微电网区域，比较典型时序场景、全周期时序场景、周期内缩减场景3类场景数据的经济运行优化结果，验证所提方法的有效性。 |

| Abstract: |
| The economic operation of microgrid involves the analysis and evaluation of different scenarios and schemes. The sequential, periodic and uncertain variation of regional loads and wind/solar power outputs affects the operation of microgrid. Typical scenario analysis method is proposed, which partitions and clusters synchronously the massive original data of wind/solar power outputs and loads for the computation period to form the typical scenarios for reflecting the characteristics of historical data. An economic operation optimization model is established for the microgrid with different distributed generations and energy storages. The results of economic operation optimization based on the scenario data obtained by the typical sequential scenario method, the complete-period sequential scenario method and the simplified scenario method for a microgrid are compared to verify the effectiveness of the proposed method. |
