Automation Is Becoming A Core Pillar Of The Future Clean Energy Ecosystem

Automation: The "Smart Link" Reshaping the Clean Energy Ecosystem

Driven by the "dual carbon" goals, the clean energy industry is ushering in unprecedented development opportunities. The deep integration of industrial automation technology is fundamentally reshaping the production, storage, and transmission of electricity. Energy systems that previously relied on manual operation are now gradually achieving autonomous operation and dynamic adaptation. While improving efficiency and ensuring safety, they are injecting strong momentum into energy transformation, becoming a core pillar supporting the future clean energy ecosystem. Automation is no longer a simple auxiliary tool, but a "smart link" spanning all scenarios including photovoltaics, wind power, energy storage, and carbon capture, driving clean energy from "feasible" to "efficient," and from "decentralized" to "collaborative."

Sensors: The "Sensing Nerves" and Monitoring Foundation of Automation

Sensors, as the "sensing nerves" of automation, provide real-time visible monitoring and control capabilities for clean energy systems, building a smart monitoring network supported by the Industrial Internet of Things (IIoT). Unlike the lag of traditional manual inspections, sensors can continuously collect real-time data on energy flow and equipment operation, allowing operators to accurately grasp the system status and achieve millisecond-level response. This sensing capability is the foundation for the efficient operation of clean energy.

Sensor-Enabled: Demand Forecasting and Multi-Scenario Safety Optimization

In the field of electricity demand forecasting, sensors in smart meters can monitor electricity consumption, voltage, and power quality in real time and feed the data back to power companies. When Advanced Metering Infrastructure (AMI) replaces traditional meters, this refined data, through machine learning models, enables accurate demand forecasting and dynamic pricing. A multi-year study in Colombia has shown that relying solely on hourly data from AMI sensors, without relying on weather input, accurate electricity demand forecasts for a week in advance can be achieved, providing reliable support for grid planning and safe operation. Simultaneously, sub-hourly load and voltage data captured by sensors can help power companies better integrate intermittent renewable energy sources such as photovoltaics and wind power, balance supply and demand through control systems, optimize the charging and discharging rhythm of energy storage devices, and solve the problem of unstable renewable energy output.

In industries such as cement and steel, where emissions reduction is difficult, carbon capture and storage (CCS) technology is a key carbon reduction pathway, and automation enables end-to-end optimization of this process. Sensors embedded in the capture plant and pipelines continuously monitor carbon dioxide concentration, pressure, temperature, and flow rate. Based on this data, the automated system adjusts the amount of carbon dioxide captured from the flue gas in real time, maintains stable compressor pressure, and provides timely warnings before leaks occur, ensuring process safety and improving carbon capture efficiency. Similarly, distribution transformer monitors (DTMs) can track transformer current, voltage, and temperature in real time, detecting potential hazards such as overload, imbalance, or overheating in advance. They send warnings through the SCADA system and respond automatically, minimizing equipment damage and unplanned power outages, while protecting renewable energy feedback power and ensuring the safety of maintenance personnel.

Smart Upgrade: Data Analysis Drives Automation Implementation
If sensors are the "sensory nerves," then advanced analytics is the "intelligent brain" of the automation system, transforming industrial operation (OT) data into actionable optimization solutions. In clean energy infrastructure, IoT technology frees sensor data from the delays and limitations of manual interpretation, directly converting it into instructions that equipment can execute autonomously. For example, when sensors detect inefficient equipment operation, the control system can adjust machine speed and optimize operating procedures in real time, achieving energy savings and consumption reduction without manual intervention. Related research shows that the combination of sensors with automated control and advanced analytics can reduce electricity consumption in industrial scenarios by 18%, reduce equipment downtime by 25%, and improve resource utilization by 15%. This achievement has been fully validated in the low-carbon smart factory built by ENN Energy for Jinko Electronics, where the energy efficiency of its refrigeration system has improved by over 50%, resulting in an annual carbon emission reduction of 2,400 tons.

In the microgrid field, digital twin analytics technology has enabled a qualitative leap in automation levels. As the "power lifeline" in remote areas or disaster scenarios, the reliability of microgrids depends on the effective management of variable energy sources. Digital twin technology, by constructing virtual copies of physical equipment and combining machine learning with real-time sensor data, enables fully automated operation of microgrids. This not only allows for predictive maintenance but also enhances autonomous decision-making capabilities, improving energy security and system resilience. This aligns perfectly with my country's development direction of promoting smart microgrid construction and contributing to carbon peaking.

Application Scenario: Automation Empowers Quality and Efficiency Improvement Across Various Fields
Modern control architectures, through automation technology, tightly connect dispersed clean energy assets to achieve collaborative operation. To address the intermittent nature of photovoltaic and wind power, deep reinforcement learning (DRL) technology is becoming the core optimization tool for hybrid energy storage systems (HESS). This algorithm combines data from sensors, such as energy output and storage status, with information from electricity prices, weather forecasts, and electricity demand, to optimize the charging, discharging, and power distribution strategies of energy storage devices like batteries, supercapacitors, and green hydrogen in real time. Its balancing effect surpasses traditional optimization methods, effectively solving the problem of wind and solar curtailment. For example, my country's pilot "flywheel + lithium battery" hybrid energy storage project achieves a complementary advantage between high-frequency frequency regulation and long-term energy storage.

In the photovoltaic field, automated adaptive tracking systems have completely broken through the efficiency limitations of fixed photovoltaic panels. Single-axis tracking systems can increase power generation by 35%, while dual-axis tracking systems can increase it by 45%. They are particularly suitable for high-latitude and equatorial regions, allowing real-time adjustment of the panel's azimuth and elevation angles to maximize the utilization of solar resources. More notably, advanced automation technology, combined with real-time meteorological data, can adjust photovoltaic panels to storage mode before extreme weather events such as hail and strong winds, reducing the risk of equipment damage and enhancing the energy system's disaster resilience. For example, the Hailutong 512KW dual-axis tracking system, through precise solar tracking and intelligent operation and maintenance, maintains a stable power generation efficiency of over 95%.

Predictive maintenance, leveraging automation technology, proactively avoids fault risks and reduces operation and maintenance costs. Taking the US wind power industry as an example, among more than 74,000 wind turbines, the gearbox is the most critical and most prone to failure. Due to load changes caused by start-up, shutdown, and strong winds, many gearboxes cannot reach their 20-year design life. By analyzing vibration and temperature data collected by sensors through machine learning models, predictive maintenance can anticipate faults and schedule maintenance during planned downtime, avoiding huge losses caused by unplanned power outages. This model is also widely used in the operation and maintenance of various clean energy equipment.

In summary: Automation leads the future development of clean energy.
Today, automation technology has permeated every aspect of the clean energy ecosystem, making energy systems smarter, more reliable, and greener. With continuous technological iteration, mastering automated system integration capabilities has become crucial for clean energy companies to enhance their core competitiveness. Automation acts as an invisible link, connecting various clean energy assets and driving the development of future power infrastructure towards greater efficiency, resilience, and economy, thus contributing to the achievement of global energy transition goals.
