| 考虑风电、光伏出力及负荷波动的随机因素，引入序列运算理论对风、光出力偏差以及负荷波动偏差的概率分布模型进行卷和及卷差运算，得到各时段净负荷概率密度函数的离散序列。在此基础上，优化满足机组爬坡等约束条件的不同可靠性水平下的微网系统正、负旋转备用。以日运行发电成本和环境成本最小为目标函数，优化可控机组出力、蓄电池的充放电以及可中断负荷。采用改进的人工蜂群算法(ABC)对模型进行求解。提出考虑微网期望停电损失、期望切风光损失费用和正、负旋转备用成本的综合经济效益CEB指标，以该指标为依据综合评估微网系统在可靠性指标为何值时旋转备用经济效益可达到最大。最后算例验证模型和算法的可行性。 |

| Abstract: |
| Considering the random factor of wind power, photovoltaic output and load fluctuation, sequence operation theory is adopted to handle the probablity density model of these fluctuate error with addition-type-convolution (ATC) and subtraction-type-convolution (STC). While the discrete sequence of pure load’s probability density function in each hour is acquired, the plus and minus spinning reserve of microgrid under different reliability levels that meeting the conditions such as unit climbing is optimized. Taking the minimum of the daily electricity generating operation cost and environment cost as the object function, this paper optimizes the output of controllable unit, the charge and discharge power of storage battery and interruptible load. Modified artificial bee colony (ABC) algorithm is used for figuring out the model. Comprehensive economic benefit (CEB) indicator, which considers expected energy interruption cost, expected wind power and photovoltaics cut cost, and plus and minus spinning reserve cost, is put forward. Based on the indicator, what value of the reliability indicator could be maximizing the economic benefit of spinning reserve in microgrid is synthetically evaluated. Finally, the praticability of the model and algorithm is proved by example.
