Research on Application of Wind-photovoltaic-energy Storage Micro-grid in 500kv Substation Station Power System

摘要

The station microgrid technology provides a flexible and efficient platform for the integration of distributed generation and renewable energy power generation technology and its application in substations. With the further upgrading of renewable energy power generation products and technologies and the further development of new energy technologies in substations, new energy and micro-grid technology will be popularized and applied in substation station power system. In this paper, the power supply system of 500kv substation in Leezhou is taken as an example, and the system of wind storage system is used as the supplementary power supply of UHV station. The distributed power capacity and energy storage in microgrid planning are designed respectively. System capacity for joint solution, while optimizing the configuration.
