Release Time：2025-11-05
TKD continues to invest heavily in R&D of high-end oscillators, providing a robust clock foundation for the realization and evolution of these advanced features, and helping photovoltaic, wind, and energy storage systems transform from mere “energy storage stations” into intelligent “energy regulation hubs.”
Under the grand blueprint of the “dual-carbon” strategic goals, building a new power system dominated by new energy sources has become an imperative of our time. The integrated approach of wind, solar, and energy storage—key to smoothing out fluctuations in new energy generation and enhancing the grid’s ability to absorb renewable power—is now ushering in unprecedented development opportunities. In this transformative energy system, every precise control mechanism and highly efficient conversion process plays a critical role. As a leading player in China’s crystal industry, TKD crystal oscillator products, though tiny as grains of rice, deliver exceptional precision and stability, providing a reliable clock reference for the microcontroller units—the “brains” of integrated wind-solar-storage systems—and thus serving as the invisible cornerstone that ensures the entire system operates efficiently and reliably.
The relationship between crystal oscillators and integrated wind-solar-storage systems.
Precise Timing: The Cornerstone of High-Temperature, High-Efficiency Systems
The integrated wind-solar-storage system leverages energy storage devices to “peak-shave and valley-fill,” transforming unstable power into a high-quality, controllable power source. This process relies on the core MCU’s real-time processing of massive amounts of data and the precise execution of sophisticated control algorithms—such as Maximum Power Point Tracking (MPPT), Battery Management System (BMS), and Power Conversion System (PCS) control for energy storage inverters.
The series of crystal oscillators provided by TKD—such as 16 MHz, 24 MHz, and 32 MHz—feature extremely low frequency deviations (ranging from ±10 ppm to ±20 ppm) and outstanding phase noise performance, providing highly stable clock signals for MCUs, DSPs, and communication modules in systems. This ensures:
1. The control circuit is stable and reliable.
In rapid power electronic switching operations, a stable clock frequency significantly reduces timing errors caused by clock jitter and phase noise, ensuring the precision of IGBT/MOSFET drive signals in the PCS and thereby enhancing power conversion efficiency and system stability.
2. Accurate and error-free decision-making
Faced with complex battery management algorithms, a precise clock ensures the periodic execution of critical tasks such as SOC estimation and equalization management, thereby preventing erroneous decisions caused by timing disruptions and significantly enhancing the system’s reliability and safety under various operating conditions.
Synchronous Communication: Intelligent Grid Connection and Remote Operations & Maintenance
The wind-solar-storage system is not an information island; rather, it needs to engage in real-time data exchange with the power grid, neighboring power stations, or cloud-based monitoring centers to achieve intelligent grid connection, participate in power grid dispatch, and receive remote operations and maintenance management.
TKD temperature-compensated crystal oscillators and other high-performance active crystal oscillators can maintain outstanding frequency stability even within an industrial-grade temperature range spanning from -40℃ to +85℃—or even wider. This provides a reliable clock source for the system’s communication modules, ensuring:
1. Grid synchronization with pinpoint accuracy.
When the inverter is connected to the power grid, it must strictly maintain synchronization with the grid’s frequency and phase to ensure grid safety.
2. Real-time and accurate data transmission
Provide stable clocks for modules such as Ethernet, CAN bus, and wireless communication, ensuring the real-time performance and accuracy of data uploads and control command transmissions, and laying a solid foundation for intelligent system operation and maintenance as well as grid-based collaboration.
With the deep integration of artificial intelligence and IoT technologies, future wind-solar-storage systems will become increasingly intelligent, requiring advanced features such as load forecasting, intelligent diagnostics, and collaborative optimization. The implementation of these sophisticated algorithms all hinges on the precise timing control capabilities of the underlying hardware.
