Optimal planning of solar-diesel generation system with energy storage

For power supply to isolated consumers, an autonomous power complex is used, consisting of photovoltaic converters, diesel generators and storage batteries. When planning the power complex, the fundamental task is to select the optimal structure of the elements of the generation system, which maximizes the use of the solar energy input to ensure the given consumer load. The article proposes a technique for optimizing a swarm of particles in relation to the problem of determining the composition and power of the elements of a solar-diesel generation system. On the example of the power supply system of the settlement of the Republic of Khakassia, the optimal structure of generating and storage facilities using solar energy has been determined. To assess the reliability indicators of the power complex, a probabilistic method has been proposed and implemented, which makes it possible to take into account the daily cyclicity and seasonal variability of the intensity of solar radiation.
