摘要
风速的随机性和相关性影响微电网潮流的分布,随机潮流模拟技术是研究这类问题的一种有效方法.在对风速、风电功率相关性进行分析的基础上,采用copula函数对相关性风速进行建模,并将抽样风速通过功率曲线转换为风电功率,将风电机组模型与潮流计算模型交替迭代,模拟微电网随机潮流.最后通过算例对微电网随机潮流进行仿真,揭示出风速随机性和相关性对微电网随机潮流的影响,为制定调度策略提供依据.
Abstract
The randomness and correlation of wind speed affect the distribution of power flow in microgrid.Stochastic power flow simulation technology is an effective method to study such problems.Based on the analysis of the correlation of wind speed and wind power,copula function is used to model the correlative wind speed,and the sampling wind speed are transformed into wind power through power curve.The wind turbine model and the power flow calculation model are iterated alternately to simulate the microgrid stochastic power flow.Finally,the stochastic power flow of microgrid is simulated by an example,and the influences of wind speed randomness and correlation on the stochastic power flow are revealed.The simulation results can provide the basis for developing dispatching strategy.
