Abstract

The invention discloses an energy management system and method for a smart micro-grid comprising a plurality of renewable energy sources. The system comprises a man-machine communication module, a data analysis module, a prediction module, a decision optimization module and a display module. The data analysis module carries out analysis on output characteristic of a micro power source and operation condition of a current micro-grid system according to information obtained by the man-machine communication module and the prediction module to obtain an optimal control scheme; and the optimal control scheme is executed by the decision optimization module. The optimal control scheme is obtained through the analysis of the data analysis module to maintain power balance of internal power of the micro-grid and the load and stabilization of voltage and frequency, so that a distributed power supply is allowed to be made fullest use of, the advantages of low carbon and economy of the micro-grid is given full play to, and system safety and power supply reliability of the micro-grid are improved.

Description

technical field [0001] The invention relates to the technical field of new energy power generation in power systems, in particular to a smart microgrid energy management system and method containing multiple renewable energy sources. Background technique [0002] Smart microgrid refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, related loads and monitoring and protection devices. Power supply reliability and end-use energy utilization. [0003] The output power of the micro power sources included in the micro grid, such as photovoltaic power generation units and wind power generation units, has the characteristics of intermittent and randomness, and the power consumption of the load is also changing all the time, which seriously affects the stable operation of the smart micro grid. At the same time, the clean and renewable power generation units included in the microgrid are s...
