新能源功率预测综合评价与预测-决策一体化OA

In the context of new power systems with an increasing proportion of renewable energy,the renewable energy power forecasting has become one of the key technologies supporting high-proportion accommodation of renewable energy,which is widely used in such aspects as security analysis,optimal dispatching,stability control,and electricity market trading.Firstly,the renewable energy power forecasting technologies and evaluation indicators are outlined,and the characteristics and applicability of the existing evaluation indicators are analyzed.Secondly,the consistency problem between power forecasting and decision-making in the existing system is discussed,and the closed-loop forecasting-decision making-evaluation framework is constructed.Then,the application scenarios of renewable energy power forecasting are summarized;the quantitative evaluation system of forecasting values is discussed;and the value-oriented renewable energy power forecasting is constructed.Finally,future research directions are explored concerning forecasting value quantification,comprehensive evaluation indicators,value-oriented forecasting technologies,and forecasting-decision making integration,in order to provide practical ideas for the development of renewable energy power forecasting technologies in the context of new power systems.
