文摘The variable nature of solar power has hitherto been regarded as a major barrier preventing large-scale high-penetration solar energy into the power grid.Based on decades of research,particularly those advances made over the recent few years,it is now believed that dispatchable solar power is no longer a conception but will soon become techno-economically feasible.The policy-driven information exchange among the weather centers,grid operators,and photovoltaic plant owners is the key to realizing dispatchable solar power.In this paper,a five-step forecasting framework for enabling dispatchable solar power is introduced.Among the five steps,the first three,namely numerical weather prediction(NWP),forecast post-processing,and irradiance-to-power conversion,have long been familiar to most.The last two steps,namely hierarchical reconciliation and firm forecasting,are quite recent conceptions,which have yet to raise widespread awareness.The proposed framework is demonstrated through a case study on achieving effectively dispatchable solar power generation at plant and substation levels.
