2025-12-12

Key words:

Recently, a spokesperson for the National Energy Administration stated at a State Council Information Office press conference that new models such as "direct green power connection and smart microgrids" will be leveraged to promote the local consumption of new energy by computing infrastructure. This policy signal indicates that, under the new paradigm of "computing power as power," smart microgrids have evolved from a technical option into a national strategic pathway supporting the greening and reliable development of digital infrastructure.

01 System Architecture: Cloud-Edge Intelligent Control, Three-Tier Coordination

Facing high-energy-consumption, high-reliability, high-green-power-demand facilities like intelligent computing centers, data centers, and new-type load clusters, how can we achieve "access to green power, effective use of green power, and efficient use of green power"? Leveraging over two decades of expertise in power digitalization and edge intelligence, Sitech Electric officially launched its self-developed Microgrid Energy Management System. Centered on "integrated hardware and software, and coordination of source, grid, load, and storage," it builds a secure, resilient, and low-carbon new-generation regional energy infrastructure.

Sitech Electric's solution goes beyond merely "adding PV + energy storage." Through intelligent coordinated regulation, it ensures every kilowatt-hour of green power precisely matches load demand, achieving a triple leap in economy, reliability, and low-carbon performance.

02 System Highlights: Hardware-Software Synergy, Full-Scope Intelligence

Hardware Foundation | STMGCC-600 Microgrid Coordination Control Cabinet

As the local "operational brain" of the microgrid system, the STMGCC-600 Microgrid Coordination Control Cabinet is the core equipment for achieving coordinated control of "source-grid-load-storage." It receives dispatch strategies from the upper-layer Energy Management System (EMS) and coordinates the optimized output of distributed resources like PV, energy storage, and loads at the edge in real-time according to constraints, ensuring safe and stable system operation.

The cabinet ensures continuous operation under extreme conditions with multiple power supplies, UPS, and a built-in protection system. Equipped with Sitech's self-developed STEMSM-1000 platform, it features full-element monitoring, multi-timescale control, and multi-protocol communication capabilities, forming a highly reliable and intelligent edge control foundation for the microgrid.

Predictive Dispatch & Optimization: Based on ultra-short-term forecasting, enables two-level optimized dispatch for off-grid scenarios.

Edge Autonomy & Reliability: Local edge decision-making allows stable operation even during communication interruptions.

04 Benchmark Projects

Currently, Sitech Electric has successfully deployed a smart microgrid project in a large-scale petrochemical scenario in Gansu Province. Centered on a 2.5MWp PV system and a 500kW/1000kWh energy storage system, the project established a campus-level smart energy system integrating generation, storage, and consumption. By deploying the self-developed Microgrid Intelligent Dispatch Platform, coordinated optimization and panoramic monitoring of PV, energy storage, and chemical production loads were achieved, significantly improving energy utilization efficiency and power supply reliability. This provides a replicable implementation model for the green, low-carbon transformation of high-energy-consumption industrial scenarios.

Simultaneously, in a high-energy-consumption large-scale industrial scenario in East Africa, Sitech Electric's off-grid microgrid benchmark project not only successfully integrated a 1.8MWp PV system, a 1000kW/2148kWh energy storage system, and a diesel generator system but also achieved multi-energy coordination and precise load control through the intelligent dispatch platform. This project marks a key breakthrough for Chinese green energy technology in overseas high-energy-consumption scenarios, forming a replicable and scalable "PV-Storage-Diesel Synergy" off-grid power supply model. It provides a stable, efficient, and replicable energy solution for the industrial low-carbon transformation of African and Belt and Road Initiative countries.

Looking towards a green future of "Computing Power + Power," Sitech Electric will continue to focus on smart microgrids, empowering high-energy-consumption scenarios to achieve energy autonomy, reliability, and low-carbon transformation, and jointly building the new energy foundation for the digital era.
