Abstract

The invention provides a master-slave type micro-grid power load prediction system based on load balancing. The master-slave type micro-grid power load prediction system comprises a main server; the main server is used for carrying out high-complexity mathematical calculation and large-scale data storage; information interaction can be carried out through an Ethernet switch and distributed secondary stations of the prediction system; the distributed secondary stations of the prediction system can transmit tasks which are required to be subjected to large-scale calculation to the main server; the main server performs calculation of the tasks; and each distributed secondary station of the prediction system is used for acquiring real-time data of fans in a micro-grid or a secondary micro-grid, real-time data of photovoltaic generated power and load data of a region. The power and the load of the micro-grid can be predicted precisely, a prediction result provides precise data support for an energy management system and a micro-grid controller, the prediction cost is reduced, and the using efficiency of a server of the prediction system and the using efficiency of a device of the prediction system are improved. Data-level load balancing can be realized on the system, and network element internal threading-level load balancing is realized in each network element.

Description

technical field [0001] The invention relates to the field of microgrid power forecasting and microgrid load forecasting, in particular to a master-slave microgrid power load forecasting system based on load balancing and a method thereof. Background technique [0002] Microgrid is a new type of power grid structure, including wind power, photovoltaic, diesel power generation, energy storage, load, control and protection modules, etc. Microgrids can realize autonomous systems of self-control, protection, and management, and can operate either in conjunction with external grids or in isolation. Microgrid can fully promote the efficient use of distributed power and renewable energy. [0003] In recent years, the photovoltaic and wind power industries have developed rapidly, and more and more small photovoltaic power generation and wind power are applied in the microgrid field. If the load data in the microgrid at a specific time in the future can be determined, it is also of ...
