METHODS AND MEANS OF CREATING AN AUTOMATED INFORMATION SYSTEM FOR ENERGY RESOURCES ACCOUNTING

Abstract

The article discusses methods and tools for creating automated information systems (AIS) for energy resource accounting in the context of the transition to distributed generation and the Smart Grid concept. The interoperability issues of modern monitoring tools caused by the use of closed proprietary protocols by equipment manufacturers are analyzed, which leads to data fragmentation and complicates the creation of a unified information space. The paper presents the results of research and development of the accounting system architecture, which, unlike existing cloud solutions, is based on the principle of local autonomy (Local-First). The proposed approach involves the use of a unified driver for Modbus and SunSpec protocols, which ensures the possibility of integrating inverters and meters of different brands (Huawei, Fronius, SolarEdge, etc.) without financial costs for specialized proprietary software. Considerable attention is paid to data collection methods at the lower level of the architecture and solving the problem of bidirectional monitoring of energy flows for active consumers ("prosumers"). The obtained results can be used to build scalable energy monitoring systems for households and enterprises, which will help increase energy efficiency and the accuracy of commercial settlements.
