Abstract:

The operating mode of thermal power generation units has certain limitations in peak shaving capacity. Interruptible load (IL), as a power resource to be tapped, can be applied to the park integrated energy management and microgrid systems to guide users to reduce peak electricity consumption. The IL function is introduced into the park integrated energy system with combined heat and power units to improve the system's peak shaving ability, and the corresponding model is established with the optimization goal of economy. Taking an ecological park of northern region as the example, the adaptive chaotic particle swarm algorithm is used in the simulation. The results show that the park microgrid after the introduction IL project can perform peak-shaving operation, and the operating economy and energy supply flexibility are greatly improved. Compared with the traditional algorithms, the adaptive chaotic particle swarm optimization algorithm is better in the optimization result accuracy and optimization efficiency.
