Energy distribution management system and method for off-grid micro-grid

Abstract

The invention discloses an energy distribution management system and method for an off-grid micro-grid. The system comprises: a data information comparison processing module, wherein a cloud computing data center for comparing and processing natural energy data and weather predication data; and a data receiving and storing module, wherein the input end of a far-end client receives external natural energy data and cloud climate prediction data and stores the data in a database. According to the invention, climate prediction data is received while electric quantity energy storage data of a generator is transmitted, and in cooperation with real-time monitoring and management of the micro-grid system,and effective control of energy is realized while the utilization rate of the energy is improved; and in addition, through a set system control scheme, and combining parameters such as fluctuation frequency of output power, power provided by a battery, power fluctuation frequency of load equipment and the like and utilizing the advantages of the micro-grid distributed power supply, the voltage of a direct-current bus can be maintained, and the problem of power fluctuation caused by renewable energy sources can be stabilized.

Description

Technical field [0001] The present invention relates to the technical field of micro-grid applications, and more particularly to an energy distribution management system of a network type microgrid and a method thereof. Background technique [0002] Due to the island and land isolation, its development and research have long been restricted by electricity, transportation, etc. And it is restricted, in addition, the use of diesel power generation is high in the island, and there will be a large amount of water pollution and noise pollution, which seriously affects the island ecological environment, and island wind energy, solar energy and other renewable energy resources. It is of great significance to sustainably the sustainable development of islands, and can be independently operated independently, can self-sufficient, meet system energy requirements, and have broad development prospects. [0003] However, in the real-time monitoring and data acquisition process of the previous...

Problems solved by technology

[0002] Due to the isolation of the island from the land, its development and research have long been restricted by electricity and transportation, and it is very difficult to guarantee electricity for remote islands. However, it is restricted. In addition, the use of diesel power generation on islands has high production costs, and at the same time it will generate a lot of water pollution and noise pollution, seriously affecting and destroying the ecological environment of the islands. However, the islands are rich in renewable energy resources such as wind energy and solar energy. It is of great significance to the sustainable development of the island to make full and reasonable use of it, and the off-grid micro-grid can operate independently, be self-sufficient, meet the energy demand of the system, and have broad development prospects

[0003] However, in the process of real-time monitoring of operating equipment and data collection in the past, it is easy to be affected by factors such as the network, weather conditions, and geographical environment, which may cause delays in the data feedback to the terminal, making it impossible to adjust the operating equipment in time, reducing In addition, electronic components such as sensors and displays involved in the operation of the microgrid are vulnerable to damage, which may affect the normal operation of the entire system. However, in this scheme, due to the output power of photovoltaic cells, there is intermittent and randomness. , the output power of wind power intermittent power supply also fluctuates
