Intelligent Microgrid Phase Ⅰ Distributed Photovoltaic Project

Focus on "Double Carbon"--"Intelligent Microgrid Phase Ⅰ Distributed Photovoltaic Project" developed by Shiyou Electric is successfully connected to the grid!

In response to the national "double carbon" development strategy, with the attention and support at all levels from the provincial, municipal and county governments, Shiyou Electric's "Intelligent Microgrid Phase I (39.96kWp) Distributed Photovoltaic Project", which was recently built in cooperation with Lenovo and Huawei, passes the approval of the power authority and is successfully connected to the grid.

This project mainly includes three parts: one is the photovoltaic power generation system, the second is the photovoltaic power station environment monitoring system, and the third is the digital energy management platform.

1. Photovoltaic power generation system

This project uses PV modules with advanced PERC cell + cell half technology, equipped with intelligent string PV controller and optimiser, which can enhance power generation up to 30%; at the same time, it eliminates the possible risk of series high voltage and arcing inside the modules,supports rapid safety shutdown at the module level, which actively protects the safety of people and property.

2. Photovoltaic power station environment monitoring system

This system is designed independently by Shiyou Electric, which can monitor the temperature, humidity, wind speed, wind direction, total solar radiation and other environmental factors of the PV power station in real time. It features stable performance, high detection accuracy and unattended operation; it is equipped with blackout protection function, and can automatically switch to the power supply of the optical storage system in case of temporary external power failure. In addition, it also has 5G wireless data transmission and video monitoring function.

3. Digital Energy Management Platform

Based on the advanced IoT platform and Lenovo data collection terminal, the company has developed a digital energy management platform, which will meet a series of functional requirements, such as visualisation screen display, multi-station status control and analysis, inverter status analysis, energy storage status analysis, weather station data monitoring, video monitoring, data report analysis, operation and maintenance control, etc.

Visualisation Display Platform

The Phase Ⅰ features high power generation efficiency, high security, high reliability, intelligent monitoring, and complete visualisation support. The successful grid connection of the project is the result of Shiyou Electric's active exploration in the field of new energy, and also contributes to the empowerment of digitalisation and low-carbon strategy.

Phase Ⅱ will be optimised and upgraded on the basis of Phase Ⅰ, and Huawei will work with us together to develop a more advanced and secure intelligent microgrid system. In the future, Shiyou Electric will continue to practice on the road to achieving the "3060" dual-carbon goal, and look forward to cooperating with various companies and organisations in the field of new energy, providing efficient and clean PV green energy for small and medium-sized enterprises, industrial parks, residential communities and other owners.
