| 摘要: |
| 因负荷和新能源出力的波动性，微电网运行状态随时间变化，在进行微电网可靠性评估时应计及运行状态的时变性。推导了不同运行状态下微电网可靠性参数的解析表达式，建立一种微电网可靠性评估模型，准确计及了运行状态间的转移特性。应用RBTS-BUS6算例验证了模型的有效性和实用性。算例分析表明：柴油发电机持续出力的策略能更好地改善微电网可靠性，对外网负荷点的影响更大；但柴油发电机作为备用的策略具有更好的环境和经济效益；增加微电网内储能电池的最大放电功率能有效提高微电网可靠性。 |

| Abstract: |
| Reliability evaluation of microgrid must consider the time-varying operation modes due to the fluctuation of load and renewable energy sources. This paper presents a reliability evaluation model of microgrid by deducing an analytical formulation of reliability parameters in different operational modes, which can be used to accurately consider the transfer characteristics between different operational modes. The RBTS-BUS6 test system is used as an example to demonstrate the feasibility and practicability of the proposed model. The results of the test system indicate that the strategy “diesel generating unit continuous output” improves the reliability of microgrid and has a bigger effect on the load points of external network, whereas the strategy “diesel generating unit in standby” has a better environment and economic benefits. A larger maximum discharging power of a battery is a useful and effective measure to improve the reliability of a microgrid. |
