Scope

Scope: This document specifies the technical requirements for basic data, prediction models, data reporting, and prediction evaluation related to photovoltaic power probability forecasting. This document is applicable to photovoltaic power stations, dispatching agencies at all levels, and prediction system development service providers conducting photovoltaic power probability forecasting work or services. Main technical content: Driven by the "double carbon goal," the large-scale integration of photovoltaic power generation has posed severe challenges to the safe and economic operation of the power system. Solving the problems of photovoltaic power integration, consumption, and power supply has placed more stringent demands on photovoltaic power forecasting. Traditional deterministic forecasting only provides single-value power forecast results, which is difficult to meet the diverse needs of dispatching operators. Photovoltaic power probability forecasting can provide a power forecast interval with a certain confidence level, effectively measure the distribution range of power forecast errors, provide dispatching operators with more valuable reference information, and strongly support the power balance and operation optimization of the power system, promoting the high-quality development of the photovoltaic industry. However, existing standards are mainly aimed at deterministic photovoltaic power forecasting. It is necessary to consider the characteristics of photovoltaic power probability forecasting when formulating this standard. This document focuses on the technical requirements for photovoltaic power probability forecasting, clarifying the technical requirements for basic data, prediction models, data reporting, and prediction evaluation that photovoltaic power stations, dispatching agencies at all levels, and prediction system development service providers need to meet when conducting photovoltaic power probability forecasting work or services.
