Problems solved by technology

[0004] When considering the uncertainty factors in the system, if only the uncertainty of one side of the source and load is considered or only the same method is used to deal with its multiple uncertainties, the uncertainties such as renewable energy generation and load forecasting errors in the system will be ignored. Their respective characteristics will make the results somewhat one-sided
