Abstract

The invention relates to the technical field of micro-grids, and provides an energy storage online pricing system and method. The pricing system comprises a micro-grid parameter acquisition device, apower grid dispatching parameter acquisition device, a reliability acquisition device, a cost acquisition device, and a controller connected with the microgrid parameter acquisition device, the powergrid dispatching parameter acquisition device, the reliability acquisition device and the cost acquisition device. The controller is configured to generate a pricing target model, and the pricing target model performs traversal optimization by using a genetic algorithm to obtain a pricing strategy. The energy storage scheduling economy of a power grid and the self-built energy storage economy of auser side are maximized, so that self-built energy storage equipment of the user side is excited, the construction investment of the power grid is delayed, the power shortage loss and the load fluctuation are reduced, and the economy and reliability of power grid operation are improved.

Description

technical field [0001] This application relates to the technical field of microgrids, and provides an energy storage grid pricing system and method. Background technique [0002] In recent years, the continuous increase of electricity load has made the transmission capacity of long-distance transmission lines continue to increase, and the stability and safety of power grid operation have declined. As a new energy network supply and management technology, the microgrid can coordinate the originally dispersed distributed power sources, ensure the reliability and security of the distribution network, and realize user demand side management and existing energy and resources. maximum utilization. [0003] As a kind of distributed power supply, distributed power supply can meet the needs of power supply in remote areas and improve the flexibility of urban power grids, save the investment in large power grids, and improve the reliability of power supply. A huge waste of energy. ...
