Abstract

The content introduces the CAIDE framework, a novel approach for managing and forecasting solar irradiance sensor farms. Key highlights:

CAIDE is designed to handle the complexities of deploying and operating multiple solar irradiance sensor farms, each interconnected with a centralized management system.
It incorporates both real and virtual replicas of sensors, facilitating comprehensive analysis of PV solar production possibilities and ensuring the robustness and adaptability of the predictive models.
CAIDE leverages Model Based Systems Engineering (MBSE) and an Internet of Things (IoT) infrastructure to support the deployment and analysis of solar plants in dynamic environments.
The framework can adapt and re-train the predictive models when given incorrect results, ensuring forecasts remain accurate and up-to-date.
CAIDE can be executed in sequential, parallel, and distributed architectures, assuring scalability through the use of the xDEVS simulation engine.
The effectiveness of CAIDE is demonstrated in a complex scenario composed of several solar irradiance sensor farms, showing its ability to manage and forecast solar power production while improving the accuracy of predictive models in real time.

Stats

CAIDE can process 164,910 sensor values per simulated second for the Oahu farm and 157,896 values per second for the Almerı́a farm.
The outlier detection service took 34 seconds to complete for the Oahu farm and 1 second for the Almerı́a farm.

Deeper Inquiries

How can the CAIDE framework be extended to incorporate other renewable energy sources beyond solar, such as wind or hydroelectric power?

To extend the CAIDE framework to incorporate other renewable energy sources like wind or hydroelectric power, several modifications and additions would be necessary:

Data Collection and Monitoring: The framework would need to be adapted to collect and monitor data specific to wind or hydroelectric power generation. This would involve integrating sensors that capture relevant variables such as wind speed, direction, water flow rates, and turbine performance metrics.

Modeling and Prediction: New predictive models tailored to wind or hydroelectric power generation would need to be developed. These models would consider factors unique to each energy source, such as wind patterns, water levels, and turbine efficiency. The existing inference and training services in CAIDE could be modified or expanded to accommodate these new models.

Outlier Detection: The outlier detection service would need to be adjusted to identify anomalies in the data specific to wind or hydroelectric power generation. This could involve detecting irregular wind patterns, unexpected changes in water flow, or turbine malfunctions.

Integration with Existing Systems: The framework would need to be integrated with data sources and systems relevant to wind or hydroelectric power generation. This could include connecting with weather forecasting services for wind energy or water level monitoring systems for hydroelectric power.

Scalability and Flexibility: CAIDE would need to be designed to handle the scalability and flexibility required for managing diverse renewable energy sources. This could involve modular design principles to easily incorporate new energy sources and adapt to changing environmental conditions.

By incorporating these modifications and enhancements, the CAIDE framework could effectively extend its capabilities to encompass a broader range of renewable energy sources beyond solar power.
