摘要
为提高微电网运行的稳定性,即系统受到扰动时使微电网具备快速调节运行状态的能力,基于场景分析建立了风电功率及分布式电源强迫停运的不确定性模型,提出一种计及风险的微电网日前随机优化调度模型,用来柔性调度微电网中的各种能源。同时,利用风险水平系数来控制微电网日前调度策略的运行风险值。研究结果表明,所提模型的有效性通过了微电网仿真系统的验证。
In order to improve the stability of microgrid operation,that is,when the system is disturbed,the microgrid has the ability to quickly adjust the operating state,based on the scenario analysis,an uncertainty model of wind power and distributed power supply forcible shutdown is established,and a kind of consideration is proposed. The risky microgrid ’s random optimization model is used to flexibly dispatch various energy sources in the microgrid. At the same time,the risk level coefficient is used to control the operational risk value of the microgrid’s prior dispatch strategy.The validity of the proposed model is verified in the microgrid simulation system.
