Research and design of off-grid solar PV power generation LED display system

Off-grid solar PV power generation system is an important application form of solar PV power generation. The purpose of analyzing the research and design of the off-grid solar PV power generation system is absorbing distributed load with the high flexibility of the system. According to the case of off-grid solar PV power generation LED display system, this article is mainly to discuss the principle and calculation of these main modules in the process of the system design, such as PV array, solar charge and discharge controller, storage battery, DC/DC converter, direct-current load and transmission module and so on.

The research on the integration of energy storage and generating wind turbine system model

In order to improve the wind power penetration, control the volatility of the wind, this paper has carried out the research on the integration of energy storage and generating wind turbine system model. The idea has been gained based on the analysis of the current wind turbine system, wind turbine system with low wind speed starting and running and the integration of energy storage and generating wind turbine system. Local energy storage, distributed energy storage and centralized energy storage has been discussed in this paper. Two kinds of wind turbine system model based on local energy storage which are energy storage in the front of generator and in the back of generator also have been studied.
