| 摘要: |
| 光电与建筑一体化（BIPV）将成为新能源和建筑节能的有效途径，对此提出了一种BIPV储能容量优化的频谱分析方法。在并网运行方式下，基于微电网平滑功率波动所需可控功率的频谱分析结果，确定用于补偿功率偏差的控制容量需求以及辅助设备和系统机组提供控制容量的能力。计算结果表明，所提方法配置的储能容量相对较小，且能够恰好地满足微电网联络线功率控制目标，并有效平抑BIPV系统发电输出和负荷用电功率波动。 |

| Abstract: |
| BIPV（Building Integrated with PhotoVoltaic） will become an effective way to enhance the building energy efficiency，for which，a method of energy storage capacity optimization based on spectrum analysis is presented. The controllable power required to smooth the power fluctuation of microgrid in the grid-connecting operation mode is processed by spectrum analysis，the results of which are used to determine the control capacity required for power deviation compensation and the capability of unit and auxiliary devices to supply the control capacity. Calculation indicates that，the energy storage capacity configured by the proposed method is relatively smaller，which can just meet the power control target of microgrid tie-line and effectively smooth the power fluctuations of BIPV output and load. |
