1 Introduction

The increasing demand for renewable energy has driven great growth in wind turbine technology, and among them is the progress made in more efficient and more reliable control systems. Automation and robotic networking have also been effective solutions for enhancing wind turbine control with better performance, reduced maintenance costs, and improved operator safety. This review article aims to give a systematic survey of state-of-the-art in this field, with emphasis on the prospect and challenge involved in adopting contemporary turbine control systems through automation and robotic networking.

Applications of automation, communication, and robot networks in controlling and optimizing wind turbines have been the area of extensive research due to the increasing demand for high-efficiency and reliable wind power generation. The complexity of wind turbine machines and uncertainty in wind speeds have necessitated the use of advanced and reliable control systems and communication equipment to enhance wind power generation and reduce downtime. Non-linearities of the wind device and system complexities of the device, along with environmental uncertainty, rank among the most challenging issues to deal with in controlling wind turbines [1, 2].

The incorporation of ML and AI in wind turbine control systems has further led to autonomous robotic systems capable of executing small-scale wind turbine system repairs. These systems utilize an optimization-enabled autoencoder/decoder algorithm for predicting electrical and mechanical failures before they take place, then dispatch an autonomous repair robot to perform the small-scale repairs.

The importance and discussion about wind turbine control systems are discussed in [3]. The adaptive robust controller for turbine speed maintenance has been designed and evaluated in [4] which shows the importance of robust control system requirement for turbine systems.

This review confirms that hybridizing automation with robotic networking of wind turbine pitch control can dramatically enhance the reliability and efficiency of wind power generation. The use of advanced control systems, such as AI and ML algorithms, can optimize wind power generation, reduce downtime, and enable the prediction and correction of faults in wind turbine systems [5].

This paper has been organized into three sections i.e. Section 2 demonstrates the level of automation utilized in wind turbine systems, Section 3 demonstrates the character of communication systems and requirements in wind turbine systems, Section 4 demonstrates the designed robotic system for condition monitoring and self-service repair of the turbines minimizing the requirements of human efforts in remotely controlled wind farms.

2 Automation in Wind Turbine Control Systems

Automation in wind turbine control systems has evolved the significantly with automated control algorithms and sensor networks. The Blade angles are optimized in real time by sophisticated algorithms to enhance responsiveness as well as energy capture. At the same time, sensor networks are offering real-time monitoring of wind conditions to enable anticipatory adjustments as well as predictive maintenance approaches, ultimately increasing turbine efficiency and reliability.

2.1 Automated Control Algorithms

In this Section 2.1, the advanced control algorithms are discussed which can optimize the performance of wind turbine power plants, and instrumentation requirements are discussed.

Wake Steering: – Wake steering is a method of misaligning upstream wind turbines from the wind direction in order to steer their wake away from downstream turbines within a wind farm. This technique optimizes overall power output and reduces the fatigue loads on turbines. An experiment by [6] demonstrated that a wind steering control algorithm could increase a wind farm’s power output by 5.6%. The experiments involved additional instrumentation and made use of supervisory control and data acquisition (SCADA) systems to monitor important components at a sampling rate of 1 Hz. Testing the ability to send and receive data on wireless networks is an exciting avenue for advancing the development of these technologies in wind turbine applications.

Yaw Alignment: – Data related to wind direction and collective control of wind turbines lead to efficient control of wind turbine power plants, which has the capability to enhance electricity production by 10.5 TWh. The highlights as the necessity of automation and supervisory control algorithms for the wind turbine-based power plants.

Automatic Shadow Flicker: – Shadow flickering is a phenomenon in which rotation of wind turbines sometimes eclipses sunlight on residential houses. This results in turbines shutting down periodically, leading to loss of income. Machine learning algorithms for automation offer a potential solution. Techniques like the RES Dynamic Flicker Optimization System (DFOS) use machine learning to recognize site images, predict weather conditions, and offer optimized choices for the operation mode of the turbine.

2.2 Automation in Fault Detection and Decision Making

The Autonomous Renewable Smart Operations Software (AROS) was developed by Green Eagle Solutions. AROS automated the wind farm operation protocol through its logic engine, reducing decision-making time for remote operation centers. AROS also includes turbine maintenance tactics, optimally utilizing poorly conditioned turbines to gain the most operating hours and automatically shutting them down at higher wind velocities. The automation enhances the turbine availability, which results in higher power output and lower levelized energy costs.

So, in order to implement these advanced control algorithms for power output optimization and parameter monitoring of wind speed, humidity, and weather conditions as well as for enabling intelligent decision-making automation, the latest reliable wireless communication technologies, i.e., 5G/LTE, are being employed now for remotely located wind farms. This ensures the safety of turbines and human resources at maintenance sites. Current technology engineered by industry leaders in this field has a throughput of 150 Mbps download and 50 Mbps upload speed per customer i.e. per SIM Card with standard frequency ranging from 800 MHz to typically 3.8 GHz.

2.3 Integration of Wireless Sensor Networks

Monitoring of the turbine performance continuously is achievable through the use of high-technology sensor networks. Furthermore, sensor data are a key factor in predictive maintenance practices [7]. Possible issues could be identified from trends and patterns in sensor data prior to leading to serious failures. Downtime is reduced while the lifespan of the turbines’ components is prolonged through this method of maintenance [8]. For instance, sensors detect the unusual change in vibrations or temperature that may indicate wear and tear or pending mechanical failures, allowing for early interventions [9].

The integration of sensor networks also enables the predictive capability of turbine control systems. Advanced algorithms can use real-time data to predict the future condition of the turbines and adjust and plan the operations accordingly. Predictive control enables optimal performance in spite of varying wind conditions to provide efficient and reliable operation of the turbines [10].

The combination of wireless communication technology, sensor networks, and sophisticated control algorithms makes the efficiency and reliability of wind turbines significantly higher. Real-time optimization and predictive maintenance are possible with these technologies, reducing downtime and increasing turbine life. Ongoing innovation with these technologies ensures improved performance and safety of operation for wind power systems.

3 Communication Systems in Wind Turbine

The communication system of wind turbines is essential for ensuring the proper operation, monitoring, and management of wind farms. It facilitates the exchange of real-time data between turbines and control centers through instantaneous communication, hence enabling automation and robotic networking. Modern wind farms include advanced communication network infrastructure using high-level architectures, including wireless technologies such as LTE, 5G, and ZigBee, as well as wired technologies like Ethernet Passive Optical Networks (EPON). These technologies provide the necessary bandwidth, low latency, and reliability required for real-time monitoring and control [11]. Utilization of the Internet of Things (IoT) in wind turbines has revolutionized their management. IoT sensors collect data from various sensors fitted on the turbines, such as those that sense rotor speed, blade pitch, and nacelle orientation. This information is then sent to a central control system that analyzes it for optimizing performance and maintenance needs [12].

Figure 1 Communication for wind farm [15].

Ramos et al. [13] report on a communication system designed to enable data communication between the nacelle and control panel of wind turbines. Through the utilization of Digital Signal Controllers and an Embedded PC, the system enhances overall and local field communication. A test of the prototype in the laboratory validated its feasibility and effectiveness with regard to facilitating automation and real-time monitoring. This development is crucial for optimizing the performance and reliability of wind turbines, allowing better maintenance strategies and operational effectiveness in wind power systems. Automation in wind turbines involves the use of advanced algorithms and machine learning in managing the operations of turbines. Robotic systems can perform tasks such as blade inspection and maintenance, reducing human intervention and improving safety. Communication systems play an important role in coordinating these robot activities and ensuring that they work properly [14]. Communication systems for wind turbines face one of the important challenges in providing stable connectivity in remote locations. Cellular communication networks, i.e., 5G, are a solution that offers broad coverage and high-speed data transmission [15]. Robust cybersecurity protection is also essential to protect the communication networks from potential attacks [15]. Advanced communication systems are an integral part of the robotic networking and automation of high-tech wind turbines. By means of modern technologies and the elimination of connectivity problems, these systems enhance the efficiency, reliability, and safety of wind power generation [16–18]. Figure 1 illustrates the functionality of the communication system in a wind farm.

The sophisticated communication systems are key to optimizing the operations of wind turbines, enabling real-time monitoring and automating processes. The integration of IoT, advanced wireless technologies, and robust cybersecurity features dramatically enhances performance and reliability. Surpassing connectivity challenges, particularly in remote areas, ensures effective and secure wind energy production.

Robotic networking for wind turbine maintenance involves using autonomous robots to inspect, maintain, and repair turbines. These robots, equipped with advanced sensors and AI, can operate in harsh weather conditions, reducing human risk and downtime. The robots perform tasks such as blade inspection, cleaning, and minor repairs that enhance the efficiency and reliability of wind power systems [19, 20].

4.1 Robot-Based Inspection Systems

Robotic inspection systems are revolutionizing wind turbine maintenance by rendering it safer, more efficient, and more precise. Robotic inspection systems, such as climbing robots equipped with high-resolution cameras, have the ability to perform close-up visual inspections of turbine blades, identifying damage or wear without requiring human technicians to ascend the turbines. This not only prevents the risk of accidents but also facilitates more frequent and closer inspections. For instance, robots can detect cracks, erosion, and other types of damage that cannot be discovered through manual inspection [21]. Moreover, these robots can work under harsh environmental conditions, which implies that inspections are not delayed due to inclement environmental conditions. The data collected by these robotic systems can be analyzed in real time, enabling immediate maintenance decisions and reducing turbine downtime. Table 1 outlines the key features and benefits of robotic inspection systems for wind turbines, highlighting their advantages and various applications. Overall, the integration of robotic inspection systems into wind turbine maintenance cycles is a milestone in the field, resulting in more efficient and stable wind energy production.

4.2 Collaborative Robotics

Collaborative robots, or cobots, can work alongside human technicians, performing repetitive or dangerous procedures and allowing humans to focus on more complex procedures. This cooperation enhances safety and productivity in maintenance operations. The application of collaborative robotics in wind turbine maintenance has emerged as a revolutionary technique for enhancing safety and efficiency. Robotic machines, such as Rope Robotics’ BR-8 robot, are able to perform maintenance procedures on turbine blades automatically, eliminating much manual labor under dangerous conditions. The robot is programmed with artificial intelligence to move through the complex geometries of turbine blades and perform repair procedures such as filling, grinding, and painting, which were previously performed by human climbers ascending tall buildings [22]. Besides, wind turbine maintenance multi-robot system design has been proposed to enhance operations further. The systems allow several robots to collaborate on maintenance activities, increasing the speed and efficiency of inspection and repair [23]. Through a robotic network, operators can attain comprehensive coverage of turbine components, leading to enhanced predictive maintenance strategies with decreased downtime and operational costs. Table 2 indicates robotic versus conventional maintenance comparison and mentions the disparity of safety, efficiency, and expense.
