| 摘 要： | 主动配电系统中含有大量的分布式电源和柔性负荷,大幅增加了配电网的供电能力和供电灵活性,但同时也给系统运行的安全性带来了新的考验。针对主动配电系统特性提出一种基于供电能力的主动配电系统安全态势感知的方法。综合考虑主动配电系统的供电能力、系统运行的脆弱性环节、间歇性分布式电源和电动汽车充放电特性等因素,在效用风险理论的基础上,提出并建立适用于主动配电系统的安全态势感知的指标体系。采用模糊层次分析法对算例进行安全态势预警等级评估,验证了所提模型及方法的可行性。

| Abstract: | There are distributed generations and flexible loads in ADS(Active Distribution System),which greatly increases the power-supply ability and power-supply flexibility of distribution network, but also challenges the security of system operation. A method of ADS security situation awareness based on power-supply ability is proposed according to its characteristics. Different ADS factors are comprehensively considered, such as power-supply ability, operational fragility, intermittent distributed generation, electric vehicle charging /discharging characteristics, etc.,and an index system of ADS security situation awareness is established based on the utility risk theory. The fuzzy AHP(Analytic Hierarchy Process) is adopted to evaluate the security situation warning level of an example to verify the feasibility of the proposed model and method. |
