Abstract
The invention provides a two-level game-based micro grid optimal and elastic energy trading method and a system and relates to the technical field of the micro-grid technology. According to the technical scheme of the invention, a non-cooperative game model is established according to a user terminal, and then the load strategy of the non-cooperative game model, corresponding to the user terminal, is optimized and scheduled. In this way, a first load strategy is obtained. According to the first load strategy, the roles of the micro-grid are determined. The roles of the micro-grid include a micro-grid the seller and a micro-grid buyer. A multi-master and multi-slave stackelberg game model is established between the micro-grid the seller and the micro-grid buyer. According to the multi-master and multi-slave stackelberg game model, the energy trading strategy of the micro-grid seller is optimized and scheduled, so that a first energy trading volume strategy is obtained. According to the multi-master and multi-slave stackelberg game model and the first energy trading volume strategy, the buying strategy of the micro-grid buyer is optimized and scheduled, so that a first buying strategy is obtained. According to the technical scheme of the invention, the earnings of the micro-grid, the utilization rate of the energy, and the sharing rate of the energy are improved.
Description
technical field [0001] The invention relates to the technical field of micro-grids, in particular to a micro-grid optimal and elastic energy trading method and system based on a two-layer game. Background technique [0002] A microgrid is a small power system that integrates distributed energy sources, distributed energy storage devices, controllable loads, and energy management systems, which enable all power devices to work together in a coordinated manner. As an autonomous and independent system, the microgrid must ensure the effectiveness and efficiency of its internal operations, and formulate strategies for energy interaction with other microgrids. The isolated grid operation mode of the microgrid requires the configuration of an energy storage system with a certain capacity, and the investment cost of the energy storage system is relatively high. The larger the capacity configuration of the energy storage system, the better the effect, but the higher the cost, it is ...
