Agricultural load modeling based on crop evapotranspiration and light integration for economic operation of greenhouse power systems

Abstract

The threat of environmental degradation attracts great attention to clean energy production and transportation. However, the limited scope of energy consumption causes the large-scale of clean energy sources to be abandoned in Sichuan province. In the meantime, the development of modern greenhouse cultivation has transformed the agriculture industry to develop a brand-new type of electrical load in the grid. Consequently, the agricultural load can be used to consume the clean energy while facilitating plant growth. In this paper, an innovative agricultural load model is proposed based on crop evapotranspiration and daily light integration. Furthermore, the proposed agricultural load model is also applied to investigate the electricity consumption of five types of crop planting. The results illustrate that the power consumption is primarily driven by an artificial lighting compensation system.
