Reliability of power supply to facilities of a local hybrid energy complex with generation based on renewable energy sources

Ensuring guaranteed power supply to consumers in isolated and distributed energy systems is achieved either by connecting the system to the electrical grid, by introducing energy storage devices on the generation side or by creating conditions for managing the amount of consumption, also including the use of energy storage devices on the consumer side. The article discusses several ways to increase the reliability of power supply when using installations based on renewable energy sources (RES) to power consumers in a hybrid energy complex. The mathematical model and algorithm proposed for optimizing the operation of the hybrid energy complex are implemented in the form of a digital twin, taking into account the influence of numerous factors, such as weather conditions and specific consumer characteristics. The digital twin of the hybrid energy complex was tested through a series of calculations that confirmed its operability and adequacy. The proposed method and the results obtained can be used in solving design tasks to validate the parameters of power supply systems for consumers in isolated and hard-to-reach areas, as well as in nodes of distributed energy systems.
