Low-Voltage Distributed Renewable Energy Load Forecasting Based on the D5000 System′s Integrated Main Distribution and Dispatch Automation System

Taking the "Solar-Storage-Charging Integrated Demonstration Project" in an industrial park of Tianjin as an example, this paper explores a low-voltage distributed new energy load forecasting technology based on the master-distribution integrated architecture of the D5000 system. Verified by engineering practices, this technology can significantly improve the grid forecasting accuracy and regulation capability under high-proportion new energy integration, solve problems such as low forecasting accuracy, large voltage fluctuation and slow manual response, and has certain promotion significance for facilitating the safe, stable and economical operation of regional microgrids.
