ЗА ENSURING THE FUNCTIONAL STABILITY OF HYBRID INVERTERS BASED ON THE SOFTWARE CONFIGURATION VERSIONING MECHANISM

Abstract

The article is devoted to the topical scientific and practical problem of ensuring the functional stability of monitoring and control systems for power complexes under conditions of dynamic technical failures and systemic anomalies. The relevance of the study is driven by the transformation of modern energy systems towards Smart Grid and the increasing complexity of control algorithms for hybrid inverters. The aim of the research is to develop software that implements a configuration versioning mechanism to support the functional stability of the power system. A mathematical model for assessing the system state through the functional stability index S is proposed, based on the logical conjunction of critical telemetry parameters: battery voltage, load current, and grid power. This model allows for the formalization of anomaly detection and the automation of decision-making regarding the necessity of configuration rollback.

The distinctive feature of the implemented architecture, based on the Django web framework and the SQLite relational database, is the creation of a flexible environment for capturing the current state of the system, which allows for comprehensive lifecycle management of configurations. Due to the developed table structure, the system automatically saves setting parameters as separate versions, providing the capability for their comparison and rapid activation.

Experimental verification was conducted on the basis of the Victron MultiPlus-II hybrid inverter using the Victron Remote Management (VRM) API. The results confirmed that the implemented versioning mechanism and the automatic rollback algorithm minimize the impact of human and software errors, ensuring stable system operation even under conditions of unstable generation and abrupt changes in energy consumption.
