Abstract

The invention discloses a microgrid optimization operation evaluation method and system for grid-connected operation. The method includes periodically collecting microgrid operation data, and the microgrid operation data includes the number of times the energy storage battery is full and the number of times the energy storage battery is empty , energy storage charging current, energy storage charging current change rate, and main grid power; according to the collected micro-grid operation data, periodically calculate the micro-grid optimization operation index through the following formula: Periodically according to the calculated micro-grid optimization The operation index evaluates the optimal operation of the microgrid. The system includes a data acquisition module, a microgrid optimization operation index calculation module and a microgrid operation evaluation module, which are used to implement the method. The method and system can optimize and control the operation mode of the microgrid according to the evaluation results, thereby improving the economical efficiency of the microgrid operation and promoting the development of the microgrid.

Description

technical field [0001] The invention relates to micro-grid operation evaluation, in particular to a method and system for evaluating the optimal operation of a grid-connected micro-grid. Background technique [0002] Traditional power generation mainly uses thermal power generation. With the depletion of fossil energy and the requirements of low-carbon and environmental protection, new energy has gradually replaced traditional power generation. Existing clean energy includes wind energy, water energy, solar energy, etc. These clean energy uses distributed power generation, also known as distributed energy. If these distributed energy sources are directly connected to the grid, it may cause many problems such as the power quality of the power system and the safety and stability of the power grid. In order to further improve the flexibility, controllability and economy of power system operation, and to better meet the higher requirements of power users for power quality and p...
