Microgrid Project Case Study: Exploring Localized Solutions for Sustainable Energy
As the world transitions to cleaner energy, microgrid projects have emerged as an innovative energy supply model, gradually gaining prominence in various regions. This article will introduce several representative microgrid projects, highlighting how they address different energy needs and challenges.
1. “Source-Grid-Load-Storage” Microgrid Project
(1) Project Background
The project is located in a remote area that has long faced challenges with low power grid reliability. The single-source power supply model could not meet the region’s growing electricity demand, and in the face of natural disasters or other emergencies, power supply disruptions were frequent, causing significant inconvenience to the daily lives and economic development of local residents.
(2) Project Composition
– Power Generation: This project achieves joint operation of wind, solar, diesel, and energy storage systems. Wind and solar power serve as the primary renewable energy sources, fully utilizing local natural resources. In addition, a 4×1.8 MW diesel generator system was installed as a backup power source to ensure continuous supply when renewable energy generation is insufficient.
– Energy Storage System: A newly built energy storage station includes a 25 MW lithium iron phosphate battery system. The energy storage system plays a critical role in the entire microgrid, storing excess electricity and releasing it during peak demand or when renewable generation is low, thereby smoothing power output and stabilizing grid operations.
– Grid and Load: After completion, the project can operate in parallel with the 10 kV grid in dual-circuit mode, capable of both grid-connected and off-grid operation, creating a backup between grids. This operational mode effectively improves power supply reliability and meets the electricity demands of various local loads.
(3) Project Benefits
– Enhanced Power Reliability: The project ends 17 years of reliance on a single power source in Ejin Banner, resolving the issue of low grid reliability in remote areas. Whether under normal conditions or in emergencies, the project ensures stable power for local residents and businesses.
– Promotion of Renewable Energy Integration: Through the rational allocation of wind and solar power generation equipment and the synergy of the energy storage system, the project enhances the integration of renewable energy. This not only reduces dependence on traditional fossil fuels but also helps lower carbon emissions, promoting sustainable local development.
The case study of Huijue Group’s microgrid project demonstrates the potential of microgrids in various regions and scenarios. Through the efficient configuration of power generation, energy storage, and grid facilities, microgrids can improve power reliability, facilitate renewable energy integration, reduce electricity costs, and contribute to local economic growth and environmental protection. With continuous technological advancements and declining costs, microgrid projects are expected to see broader applications in the future, becoming a key force in the global energy transition.
