The Influence Of Different Load On Control Voltage Of The Battery In Control System Of Wind/Solar Hybrid Generation

The compound utilization of renewable energy resources is an effective way to practice sustainable development strategy in our country. Solar and wind are two kinds of widely used renewable resources. There are complementary characteristics between these two renewable resources. In regions far away from power transmission network, wind/solar generation makes affective effect.In order to promote applications of wind/solar hybrid generation, two problems must be well resolved. One is optimal unit sizing, another is operational control. The destination of the former is to achieve the least investment collocation, while the later destination is to assure the hybrid generation system running normally itself. The control voltage of the battery is the core of operational control. All the investment collocations are based on the control voltage which also guides the optimal unit sizing. So the research of control voltage has an important significance to these problems.This paper, using the Electronics Workbench software, found the same math models of the real equipments and use different investment collocation to get the useful data and confirm the best control voltage and investment collocation. We compare the data which is got from the software to the data which is got from the real project and achieve the aim of taking full advantage of the equipment, saving energy, saving operating expenses. If there is a same project using different equipments. We can change the corresponding math models and confirm the investment collocation and Control Voltage rapidly. The analysis also guides the chosen of equipments.
