Abstract
The invention provides a method and device for managing source-grid-load-storage interaction energy in a micro-grid. The method comprises steps of obtaining a load demand, energy storage information and various energy supply situations; substituting the load demand, the energy storage information and the energy supply situations into a pre-established energy management model, solving the energy management model by a genetic algorithm to obtain the output power of various energy sources and the charging-discharging power of an energy storage system. The energy management model is constructed bytaking account of energy supply and demand balance to maximize the utilization of light energy based on a load demand response. The various energy supplies include distributed energy supply and gridsupply. The energy management result obtained by the method has high accuracy and improves the operating efficiency of the micro-grid. The method considers the source-grid-load-storage interaction relationship in the micro-grid, realizes the economical and efficient operation of the micro-grid, and improves the utilization level of clean energy. The method not only minimizes the operating cost ofthe micro-grid, but also has no negative impact on the user's power consumption experience, and improves user satisfaction and comfort.
Description
technical field [0001] The invention relates to the technical field of micro-grids, in particular to a method and device for managing source-network-load-storage interaction energy in a micro-grid. Background technique [0002] With the increasingly serious energy crisis and environmental crisis, renewable energy has been widely concerned and applied in the field of power generation. However, the large-scale direct grid connection of distributed power will lead to the instability of the power system. As an efficient and safe way to utilize clean energy, microgrid has begun to be developed and applied on a large scale. [0003] Microgrid is a new power supply method integrating renewable energy generation technology (wind power generation, photovoltaic power generation, biomass energy, tidal energy, etc.), energy management system and power distribution infrastructure. It can not only improve energy utilization efficiency and power supply security, but also reduce power loss...
