Layered energy optimization scheduling method of active power distribution network considering environmental benefits

Abstract

The invention discloses a layered energy optimization scheduling method of an active power distribution network, belongs to the field of intelligent power distribution networks, and particularly relates to a layered energy optimization scheduling method of an active power distribution network considering environmental benefits. The method comprises the steps as follows (1) a distributed unit which directly participates in active power distribution network optimization scheduling is divided into a distributed power unit, a distributed energy storage unit, a load and a microgrid group comprising a plurality of microgrids, and optimization scheduling is carried out in three layers; (2) an active power distribution network scheduling center collects and gathers relevant output information reported by distributed power supplies, an energy storage device and a microgrid group scheduling center and interaction electrovalence of the power distribution network and a superior power grid, and first layer optimization scheduling is carried out by combining loads connected to the power distribution network; and (3) middle layer optimization is optimization of the microgrid group scheduling center on the basis of upper layer optimization; and (4) bottom layer optimization is optimization scheduling of various microgrids in the microgrid group on the basis of middle layer optimization.

Description

technical field [0001] The invention relates to an energy hierarchical optimization scheduling method of an active distribution network, which belongs to the field of intelligent distribution networks, and in particular relates to an energy hierarchical optimization scheduling method of an active distribution network considering environmental factors. Background technique [0002] At present, the world's energy consumption is dominated by fossil energy. The depletion of fossil energy and climate change have become two key issues that threaten the sustainable development of human beings. In order to change the old energy production and consumption patterns and change the energy pattern dominated by fossil energy, all countries in the world are working hard to explore new energy production and consumption patterns and seek diversified energy supply strategies. In recent years, distributed energy systems that mainly utilize clean energy or renewable energy have developed rapidl...
