摘要: 随着社会的发展,具有随机性、间歇性的风电等新能源大规模接入电网。同时,负荷侧结构变动、用电主观性以及预测技术的限制使得调度中的负荷需求难以准确获取。这些因素导致电力系统中的不确定性愈发呈现“奈特氏不确定性”的特性,使得电力系统调度成为一项十分具有挑战性的工作。为此,该文采用一种新的非概率性方法——信息间隙决策理论(information gap decision theory,IGDT)对风电输出功率和系统负荷需求的不确定性进行建模,建立了风险规避和机会寻求2种策略下的IGDT调度模型,解决了电力系统调度中风电和负荷的奈特氏不确定性。最后在改进的IEEE-39节点系统上对所提模型进行算例分析,结果分析以及蒙特卡洛模拟证明了所提IGDT模型的有效性。

Abstract: With the development of society, new energy sources, such as wind power, which have randomness and intermittency, have begun to connect to the power grid. At the same time, the change of load side structure, the subjectivity of user and the limitation of prediction technology make the actual load demand difficult to be obtained accurately. These new factors have led to increased "Knightian Uncertainty " in the power system, which makes power system scheduling become a very challenging job. The paper makes use of a new non-probabilistic approach-information gap decision theory (IGDT) to model the uncertainty of wind power output and the system load demand. And two models are deduced in risk averse and opportunity seeker strategies for dispatcher, which solves the Knightian Uncertainty of wind power and load in power system. Finally, the analysis is examined on Modified IEEE 39-bus system, and the validity of IGDT model is proved by result analysis and Monte Carlo method.

Key words: power system dispatching, information gap decision theory(IGDT), wind power, uncertainty
