SynSta Smart Microgrid Solution
Reliable power cannot be taken for granted in remote and challenging environments, where limited grid access, unstable supply, and growing energy demands create significant challenges. Microgrids provide a resilient and flexible energy solution by integrating renewable generation, energy storage, and intelligent control, enabling efficient operation in both grid-connected and islanded modes. Sieyuan delivers smart microgrid solutions that strengthen energy resilience, maximize renewable energy utilization, and accelerate sustainable energy transformation worldwide.
Key Challenges in Microgrid Applications
-
01
Weak-Grid and Off-Grid Reliability
Weak-grid and off-grid environments face limited power reliability, poor resilience, and difficulties in maintaining continuous energy supply.
-
02
Complex Multi-Source Coordination
Complex coordination among multiple energy sources requires advanced control strategies to achieve stable and efficient microgrid operation.
-
03
Reliance on Diesel Generators
High dependence on diesel generators increases operating costs and carbon emissions, limiting sustainable energy development in remote areas.
-
04
Renewable Energy Fluctuations
Renewable energy fluctuations cause voltage and frequency instability, challenging reliable microgrid operation under high renewable penetration scenarios.
What Sieyuan Deliver
-
Self-Developed Power Generation and Load Forecasting Algorithms
Our self-developed algorithms combine high-accuracy wind and solar generation forecasting with dynamic load prediction to drive data-based control strategies that lower energy costs and improve system economics. Using a hybrid model with ARIMA time-series analysis, we build tailored forecasts that factor in holidays, terrain, seasonal climate, and historical load curves. The system then adjusts generation schedules around the clock, smoothing renewable output, minimizing curtailment, and maximizing local renewable energy use.

Utility-Scale Grid Security and Stability Philosophy
We bring the field-proven security and stability control logic of bulk power grids into our microgrid systems, creating multi-layer protection. It handles transformer inrush currents, large motor starts, sudden source outages, and short-circuit faults while keeping frequency and voltage within permissible limits. For power-sensitive users like semiconductor fabs and precision manufacturing, our switching algorithm delivers uninterrupted, disturbance-free supply during transitions between grid-connected and islanded modes, eliminating production losses from power fluctuations.
-
Fully In-House Core Products
Sieyuan develops the entire microgrid control stack in-house, including EMS, coordinated master controllers, grid-forming units, and emergency stability control devices. Our integrated control system applies the power industry's three lines of defense to suppress frequency and voltage fluctuations under complex conditions. Backed by a full primary and secondary equipment portfolio, from grid-forming battery storage and protection devices to MV/LV switchgear, prefabricated cabins, and distribution transformers, we offer one-stop procurement that simplifies coordination, shortens delivery, and unifies after-sales support.

Integrated Planning and Simulation Solutions
From site selection and capacity optimization to system modeling, control strategy design, and stability assessment, Sieyuan provides end-to-end planning for commercial, industrial, and off-grid microgrids. Our toolset includes HOMER, PSCAD, and field-proven RTDS hardware-in-the-loop (HIL) platforms. For complex projects, we run pre-delivery HIL tests on full station models, covering grid-connected and islanded operation, mode switching, black start, protection settings, and EMS optimization. The result: fine-tuned parameters, fewer logic defects, and optimal performance across all operating conditions.
