Problems solved by technology

However, when using QPSO to solve the micro-energy network scheduling model, it is found that the particles are constantly moving closer to the optimal position of the population during evolution, which reduces the diversity of the population and easily falls into a local optimal solution in the later stage of iteration.

Description

technical field [0001] The invention belongs to the technical field of electric power dispatching, and relates to an optimal dispatching method for a micro-energy network based on an improved quantum particle swarm algorithm. Background technique [0002] With the depletion of global fossil fuels and the increasingly serious environmental problems, building a low-carbon, clean, safe and efficient energy system has become the main focus of energy development in the world today. The concept of "Internet +", "Integrated Energy System" and "Energy Internet" has become a new wave of energy development, providing a new perspective for energy analysis. As the terminal energy supply system of the Energy Internet, the micro energy network is an inevitable choice to realize multi-energy mutual aid and energy cascade utilization. [0003] Relying on the background of "Energy Internet", the micro-energy grid extends the traditional micro-grid and is a multi-energy interconnection syste...
