Abstract

Abstract: With the rapid development of energy technology, wind/photovoltaic-hydrogen production system will play a major role in the typical energy scenario. Based on the analysis of the power exchange characteristics of heterogeneous energy in wind/photovoltaic hydrogen production system, a homogenization analysis model of wind/photovoltaic-hydrogen production system was established from the perspective of power / energy supply and demand balance. Based on the analysis of the operation domain of the model, a unified analysis framework was formulated, and three dimensional analysis was conducted to study the boundary conditions of wind/photovoltaic-hydrogen production system. Furthermore, the output scatter diagram was plotted using the historical data to figure out the pattern of operation point as well as the index range of operation point such that the system operation domain can be analyzed reasonably.

Key words: homogeneous model, wind/photovoltaic power generation, hydrogen production system, boundary condition, operation domain
