Abstract

The paper analyzes the state of renewable energy monitoring systems, including systems for small-scale and micro-generation plant in Russian regions. The study revealed a lack of open and structured data on micro- and mini- renewable energy plants. Existing state registries primarily cover large facilities supported under capacity supply agreements. The content of international open databases, such as the Global Solar Atlas and Global Wind Atlas, was analyzed. They contain regionally averaged values of solar insolation and average wind speed. These sources primarily contain climatological long-term averages norms, but do not provide the operational data necessary to assess the current efficiency of a specific micro-plant. The developed system consists of application programming interface and IoT solutions based on ESP32 microcontrollers for collecting climate and energy parameters in real time. The system architecture includes local data collection, data transfer via application programming interface, and provides both local and centralized data storage. A prototype system has been developed, including a microcontroller node, a server component, and a web interface for time series analysis. Implementation of this system will improve the transparency and manageability of distributed renewable energy generation at the regional level.
